By creating a flow chart below, trace the steps from DNA through to the resulting phenotype. It has been started for you
below The following words must appear in this flow chart transcription, translation, amino acid(s), protein, gene, mRNA,
TRNA, phenotype
DNA

Answers

A correct flow chart is DNA i.e., gene (transcription) >> mRNA + tRNAs (translation) >> amino acids or protein >> phenotype.  It is the flow of the genetic information.

What is the flow of genetic information?

The flow of genetic information refers to the molecular process from DNA to the final phenotype (i.e., protein product).

During gene transcription, a particular fragment of DNA called gene is used as a template to generate an mRNA.

Subsequently, the mRNA serves as a template to generate a linear chain of amino acids, i.e., a protein, by a process called translation.

The final protein can be considered as the phenotype (in this case, the albinism trait) because it is the observable feature.

True or False: All point mutations will result in a missense mutation.

Answers

Answer:

A point mutation affects a single base pair. A point mutation may cause a silent mutation if the mRNA codon codes for the same amino acid, a missense mutation if the mRNA codon codes for a different amino acid, or a nonsense mutation if the mRNA codon becomes a stop codon

A missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes. Changes in amino acid can be very important in the function of a protein.

Explanation: hope this helps;0

All point mutations will result in a missense mutation. The statement is false. This is because a point mutation can result into silent mutation, a missense mutation, or a nonsense mutation.

What are Point Mutations?

A point mutation affects a single base pair in the DNA sequence. A point mutation may result into a silent mutation if the altered mRNA codon encodes for the same amino acid, a missense mutation if the altered mRNA codon encodes for a different amino acid, or a nonsense mutation if the altered mRNA codon becomes a stop codon.

A missense mutation is a mistake in the DNA sequence which results in the synthesis of wrong amino acids which are being incorporated into a protein molecule because of the change, that a single DNA sequence change results in a different amino acid synthesis which the ribosome recognizes.

Heterotrophs are organisms that consume other organisms in order to gain energy. Compare two different categories of heterotrophs in
terms of how they obtain energy. Explain your answer in one to two sentences. (2 points)

Answers

Primary consumers and secondary consumers are both heterotrophs. These organisms cannot produce their own food.

What are consumers?

In a food web, consumers are heterotrophic organisms that need to eat other organisms to survive.

Primary consumers such as herbivores and secondary consumers such as carnivores are heterotrophic animals because they cannot produce their own food.

These animals are mutually related in a food web because the removal of primary consumers may lead to a decrease (even removal) in the population of the next trophic level.

What ethical questions exist from using CRISPR technology?

Answers

Most ethical discussions about genome editing center on human germline editing because changes are passed down to future generations.

Answer:

Even if editing human genes is ethical, it would certainly cost money to edit your children. With that said, people with more money would be able to create stronger, faster, and smarter children. Anyone without enough disposable income would have normal babies. In essence, the physical capabilities of future people would be split by class. Thus, is it ethical to allow the divide by social class to be exacerbated by gene editing?

b.Gene sections appear in different locations on homologous chromosomes

The false answer is B because to be exact, the two copies of a gene carried by an organism (such as a Y and a y allele) are located at the same spot on the two chromosomes of a homologous pair. Homologous chromosomes are similar but non-identical, and an organism gets one member of the pair from each of its two parents.

What is MRI?

MRI stands for Magnetic Resonance Imaging. It is a type of scanning that produces detailed images of the inside of the body by using a strong magnetic field and radio waves.

The spatial resolution of EEGs (electroencephalography) is comparatively low as compared to MRI and fMRI. While the temporal resolution of EEGs is as high as that of the others two. The spatial resolution of EEGs is low because it lacks the precision of scanning images.

Therefore, MRIs and fMRIs produce high-resolution, three-dimensional images.
