bicoid is a gene that produces a porphogen. what results when there is a high concentration of the bicoid protein in a devlopoing [mebryo
A high concentration of bicoid protein at the opposite ends of a developing Drosophila embryo would result in the development of a two-headed fly.
Bicoid acts as a morphogen during Drosophila development. Thus, BCD mRNA is maternally located at the anterior pole of the embryo and Bcd forms an anterior/posterior gradient that functions in a concentration-dependent manner. Both functions require a homeodomain that recognizes.
DNA motifs on target gene enhancers and specific sequence spacing of her 3 untranslated regions of the tail mRNA. Female embryos with the bicoid mutation lack the head and thorax replaced by a posterior telson. Embryos lacking both maternal and zygotic hb show reduced and anterior shifts of ems and btd expression at the blastoderm stage.

you are doing a biochemical analysis of molecules from cells from patients with a certain disease compared to cells from control patients who do not have the disease. you find that patients with the disease have unusually high levels of cytosine molecules with ch3 groups attached to their cells. which modification has taken place in the cells from the disease patients?
Plantae have the highest levels of methylation among eukaryotes, with methylation present in up to 50% of their cytosine residues.
What is methylation of cytosine?In both bacteria and eukaryotes, cytosine methylation is a frequent type of post-replicative DNA alteration. Due to the high probability of spontaneous deamination of this base to thymine, which results in a G/T mismatch, modified cytosines have long been recognized as acting as hotspots for mutations.
What takes place when a methyl group binds to a gene?The process of attaching methyl groups, which each contain one carbon atom and three hydrogen atoms, to DNA building blocks is known as DNA methylation.

In oviparity, fertilized eggs are kept inside the female, but the embryo receives nutrition from the yolk of the egg, and the offspring are fully formed when they hatch.
Which phrase best describes the growth of eggs within a female?Oogenesis is the name for this process of egg development. Once she reaches adolescence and begins to mature, her reproductive cycle will begin. One egg from this supply of eggs in her ovaries will then mature or become activated each month, allowing it to be fertilized by sperm.

The backbone of DNA consists of ______.
a) paired nucleotides
b) a repeating sugar-nucleotide-sugar-nucleotide pattern
c) nitrogenous bases
d) a repeating sugar-phosphate-sugar-phosphate pattern
The backbone of DNA is made up of a sugar-phosphate-sugar-phosphate pattern that repeats itself.
What is the structure of DNA?DNA is a nucleotide-based double helical structure. Hydrogen bonds hold the two helices together. A sugar-phosphate backbone is also present in the DNA.Nucleotides are the building blocks of DNA and are composed of three components: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base.A double helix is a twisted ladder-like structure composed of two interconnected strands winding around each other. Each strand has a sugar (deoxyribose) and phosphate backbone that alternates. Each sugar is connected to one of four bases: adenine (A), cytosine (C), guanine (G), or thymine (T).Understanding the structure and function of DNA has revolutionized disease pathway research, assessing an individual's genetic susceptibility to specific diseases, diagnosing genetic disorders, and developing new drugs.

Experiments with genetically altered mice showed that the mice would consume abnormally high amounts of bitter-tasting compounds in water after their _____.
Sweet taste cells were modified to express bitter taste receptors, suggesting that the sensation of sweetness depends solely on which taste cell is competent.
we investigated the effect of prolonged exposure to a bitter substance on recognition and aversion behavior in mice. Combined measures of rejection thresholds (RjT) and apparent recognition thresholds (aRcT) were performed using short-access two-bottle choice tests before and after taste aversion conditioning, respectively. First, RjT was higher than aRcT for the bitter amino acids L-tryptophan and L-isoleucine, which mice measure daily in their diet, indicating strong acceptance of these familiar stimuli within the concentration range between RjT and aRcT.

. why do you think four molecules of catecholamine neurotransmitters are generally bound to each molecule of atp?
In four neurotransmitter molecules the catecholamine is bound to each molecule of ATP because the synaptic vesicles and synaptic granules on the neurotransmitter contain adenosine triphosphate with a molar ratio of catecholamine to ATP of approximately 4:1.
Hormones that play a role in the nervous system are catecholamines in the form of epinephrine (adrenaline) and norepinephrine (noradrenaline). The adrenal medulla contains chromaffin granules (organelles in cells) which function for the biosynthesis, absorption, storage, and secretion of catecholamines.
Other compounds contained in these granules are ATPMg2+, Ca2+, Dopamine-β-hydroxylase (DBH), and the protein chromogranin. Catecholamines enter the granules by a transport mechanism with an ATP-dependent ratio of catecholamines : ATP = 4 : 1. Norepinephrine is stored in the granules, can leave and undergo methylation of the N-terminal end of the protein to form norepinephrine and then enter new granules.

What are the common types of mutations that occur to convert proto-oncogenes to oncogenes?.
Missense and amplifications are the common types of mutations that occur to convert proto-oncogenes to oncogenes.
Missense mutation is a mutation in a gene's DNA sequence that causes an amino acid (a protein building block) to be swapped out for one that is not normally present at that location in the gene.
Amplification mutation is a rise in the gene's copy number. Additionally, there can be an increase in the RNA and protein produced by that gene. Cancer cells frequently experience gene amplification, and some of these amplified genes may enable cancer cells to proliferate or develop therapeutic resistance.

which statement is false about the skeletal alterations caused by chronic renal failure? when the glomerular filtration rate (gfr) declines to 25% of normal
A adequate amount of parathyroid hormone can no longer be secreted by the parathyroid gland .
GFR declines when the macula densa notices an increase in the concentration of NaCl in the renal filtrate.By monitoring filtrate osmolarity, the macula densa controls the body's blood pressure. If it falls too low, it causes the kidney's afferent arterioles to constrict, increasing pressure at the glomerulus and increasing glomerular filtration rate.Increased sodium chloride supply to the macula densa causes the production of adenosine, which causes vasoconstriction when it binds to the afferent arteriole. GFR is reduced as a result of the vasoconstriction.It is thought that the distal tubule fluid's sodium content and maybe the speed at which the fluid passes through them cause the macula to react.

Individual 4 was found to have a genotype of Cc, which means individual 4’s phenotype is
A. healthy male
B. male with cystic fibrosis
C. healthy female
D. female with cystic fibrosis
The answer is B, right?
Answer:
The correct answer should be A
Explanation
Since we know the genotype of individual 4 to be Cc (heterozygous), and C indicates a healthy person. In contrast, c indicates having cystic fibrosis. We can conclude that this person is healthy. C is dominant over c; therefore, this person does not have cystic fibrosis. If this person did have cystic fibrosis, they would need to be homozygous recessive (cc). This does mean, however, that since the person has the recessive allele (c) for cystic fibrosis, they are a carrier of it. That means that if they were to have children with someone who had cystic fibrosis (cc) or was a carrier of the recessive allele (Cc), their children could possibly have cystic fibrosis.

What makes up the inside or the steps of a DNA molecule?
Answer:
The sides of the backbone of DNA are made up of alternating sugar (deoxyribose) and phosphate groups. The inside of the DNA molecule, or the "steps" as you put it, consists of the bases: adenine, guanine, cytosine, and thymine. These bases pair up with each other in specific ways: adenine always pairs with thymine, and guanine always pairs with cytosine. This is what gives DNA its unique double-helical structure and allows it to store genetic information.
Answer:
The backbone of a DNA molecule consists of the phosphate groups and the deoxyribose sugars, whereas the base of the DNA molecule consists of nitrogenous bases, therefore, the backbone of DNA is made up of phosphate groups and pentose sugars. Adenine is a part of the base of the molecule.
