The first three amino acids coded by this new mutated sequence are Glutamine, Alanine, and Lysine.
One triplet nucleotide is coded for by one amino acid. Therefore, there are 16 nucleotides altogether following the insertion of the adenosine residue. The mRNA sequence will thus encode five amino acids. A codon is a collection of three nucleotides that are found in mRNA, and each codon designates an individual amino acid (hence, it is a triplet code). Thus, the chain of amino acids that makes up a protein is assembled in accordance with the template provided by the mRNA sequence and this is how Glutamine, Alanine, and Lycine form.
A gene encodes the amino acid composition of a polypeptide. The polypeptide's amino acid composition is determined by the bases in the gene's DNA. Proteins can either have a single polypeptide or many polypeptides linked together. All of a cell's or an organism's generated proteins are found in the proteome. A codon is a group of three DNA or RNA nucleotides that specify an amino acid or serve as a signal to cease protein production.

Describe the climate changes that are happening in the world in our time, and name some of the causes of climate change. Tell which of these causes come from human activity and which of them are from natural sources. From your personal perspective, describe one positive and one negative aspect of climate change. (10 points)
climate change is the a shift in an area's typical weather patterns. Climate change is a result of a variety of natural and anthropogenic (caused by humans) processes. Although climate change has always occurred on Earth, as is shown from the geological record, it is the current rate and severity that are causing so much anxiety on a global scale. The atmosphere's greenhouse gases trap heat radiation.
Causes of climate change
Human activity can be seen a major cause of climate change because of the greenhouse gas emissions we produce, humans are mostly to blame for climate change. As heat from the sun travels through Earth's atmosphere, greenhouse gases capture it.
Naturally a volcanic eruption is commonly known to alters the climate due to volcanic activity leading to climate change
From my perspective major benefit of climate change include lower energy demand for heating and crop fertilization with carbon dioxide, while the negative effect can be seen as increased temperature because of an increase in atmospheric gases caused by industrial activities
Conclusively Climate change can affect our health, ability to grow food, housing, safety and work.

Write a description (100-200 words) of a scenario to explain the changes in biodiversity between your two samples.
Answer:
Biodiversity is the variability of living organisms from all sources, including terrestrial, marine and other aquatic habitats, and the ecological complexes to which they belong ; this involves the variety of species, species and ecosystems.The significance of this concept is that the many aspects of biodiversity are drawn to attention. It explicitly acknowledges that each bio ta can be described by its taxonomic, ecological, and genetic diversity and that a main characteristic of biodiversity is how these dimensions of diversity differ over moment and space. Therefore, only a multidimensional biodiversity evaluation can provide insights into the connection between changes in biodiversity and changes in the functioning of ecosystems and ecosystem services.

Histamine binds to the h1 g-protein-linked receptor to initiate the itchiness and airway constriction associated with an allergic response. If a mutation in the associated g-protein’s alpha subunit prevented the hydrolysis of gtp how would the allergic response change?.
Additionally, G protein mutations can result in either a loss or gain of function by inhibiting or stimulating signal transduction, which, in turn, results in the clinical phenotypes of an excess or a deficiency of hormones.
What renders the G protein's alpha subunit inactive?The alpha subunit switches its GDP for a GTP when the neurotransmitter dopamine activates the receptor. The G protein subsequently breaks down. The beta and gamma subunits are left behind when the alpha subunit, which is carrying GTP, moves away.
The state of the receptor is altered when a ligand known as an agonist stimulates it. In order to activate G alpha, GTP must be exchanged for the bound GDP after G alpha separates from the receptor and G beta-gamma. The next step for G alpha is to activate more cell molecules.
GPCR mutations can result in hereditary and acquired conditions such retinitis pigmentosa (RP), hypo- and hyperthyroidism.

Gregor Mendel was a poor youngster from Austria at the time. Due to the importance, they placed on math and science, his professors advised him to become an Augustinian monk in 1843. He continued his education at the University of Vienna, he continued his education. Mendel spent eight years researching heredity through the use of the simple-to-breed pea plant (Pisum sativum). He crossed the plants and performed hybridization studies on approximately 29,000 plants, which allowed him to change 7 of the plants' obvious traits: plant height, pod shape and color, seed shape and color, and bloom position and color.
He did this by applying pollen with a paintbrush. He is now regarded as the founder of modern genetics, despite the fact that it was decades after his death that his discoveries were confirmed. He wrote about the invisible "factors"—what we now refer to as "genes") that determine apparent features in his 1866 publication.

What is PCOS?
PCOS with full meaning "Polycystic Ovarian Syndrome" is a common disorder of the endocrine system that is diagnosed based on inclusion criteria of an ovulation or oligo–ovulation, presence of polycystic ovaries on ultrasound. From research, it has shown that many women with PCOS also have hyperinsulinemia, leading to over production of ovarian androgens. This has led to several studies on the use of the insulin–sensitizing agent metformin in inducing ovulation in women with PCOS. Metformin combined with the fertility drug clomiphene citrate (clomid) has shown to be more effective than the placebo in stimulating ovulation. While metformin has not yet gained the title of a first–line pharmacological agent for ovulation induction, research shows it has many benefits in PCOS treatment.

20 pts!!! For the following questions, create a Punnett square. Be sure to show the genotypes, phenotypes, and percentages for each cross.
In peas, side flowers are dominant over end flowers. Cross a homozygous recessive plant with a heterozygous plant. (4 pts)
Genotype: Phenotype
The genotype of the cross is 50% Aa and 50% aa.
The phenotype of the cross is 50% side flower and 50% end flower.
Monohybrid crossingThe problem here has to do with a crossing involving a single gene. That is a monohybrid cross. Crosses involving two traits are known as dihybrid crosses.
Let us assume that the side flower allele is represented by A (since it is the dominant allele) and the end flower allele by a (the recessive allele). The dominant allele masks the expression of the recessive allele when they are together. Hence:
The genotype of a homzygous recessive plant = aa
The genotype of a heterozygous plant = Aa
Crossing Aa and aa:
Aa x aa
Aa Aa aa aa
The genotype of the offspring from the cross:
= 50%(1/2) Aa and 50% (1/2) aa
The phenotype of the offspring from the cross:
= 50% Aa (side flowered) and 50% aa (end flowered)
Thus:
Genotypes = 50% Aa and 50% aaPhenotype = 50% side flower and 50% end flowerSee the attached image for Punnet's square.

Which respiratory function describes the exchange of oxygen and carbon dioxide in the cells?.
Answer:Cellular Respiration
Explanation:
Cellular respiration is the process by which cells produce energy, and is broken down into three more steps: glycolysis, Kreb’s cycle, and electron transport chain. Glycolysis requires glucose, two ATP, and NAD+, and two ADP, and produces two pyruvate, four ATPs, two NADH, and two H2O. The Kreb’s Chcle and thus the downstream electron transport chain require acetyl-CoA, one ADP, three NAD+, and one FAD, but pyruvate oxidation needs to happen prior to the Kreb’s Cycle, thus this is where the Oxygen is used and produced into two CO2.
