To determine:
The differences in the effect of the mutation produced in a gene’s promoter and protein-encoding region.
Introduction:
The mutation is a change in the sequence of the cell’s DNA, which results in the formation of an altered protein. The substances that cause mutation are collectively known as mutagens. The promoter of the gene is responsible for initiating the transcription of the gene. The protein coding region of the gene is the portion that codes for a protein.
To determine:
The difference in the effect of mutation produced in intron and exon.
Introduction:
The mRNA that is made after transcription consists of both introns and exons. The introns are the non-coding regions, which do not code any protein. Exons are the protein coding regions which codes for the protein. The introns are removed after processing, and then only coding mRNA proceeds for translation.
To determine:
Whether the type of mutation affects the answer given by an individual.
Introduction:
The mutation is an alteration in the sequence of the cell’s DNA, which results in the formation of an altered protein. The substances that are involved in causing mutation are collectively called mutagens.

- How much protein should Sarah add to her diet if she gets pregnant? Sarah's protein requirements during pregnancy would be higher. See Hint B2. During calculations, use numbers rounded to the first decimal place. In your answer, round the number of grams to the nearest whole number. _______ g ?arrow_forwardC MasteringHealth MasteringNu X session.healthandnutrition-mastering.pearson.com/myct/itemView?assignment ProblemID=17396422&attemptNo=1&offset=prevarrow_forwardMost people, even those who exercise regularly at low to average intensity (1 hour at the gym or a 2- to 3-mile walk several times per week), do not need an increased protein intake. What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place. Because protein requirement is a range, please enter two numbers: lower and upper range values, respectively. Separate the lower and upper range values, in that order, by a comma. ___, ___ g ?arrow_forward

Current treatments are focused on highlyactive antiretroviral therapy (HAART). HAART usually consists of an orally delivered drug cocktail containingtwo different reverse transcriptase inhibitors and one other drug, such as a protease inhibitor. Question: Develop a pharmacokinetic model of HAART treatment. Consider all 3 drugs. Make sure to include adiagram that illustrates your thinking, state all assumptions, and define your variables. Whatparameters would you need to know to find the concentration of drug in the plasma? In the T cells?(You do not need to write out or solve any equations.)arrow_forwardnot use ai pleseaarrow_forward

If you add heterotrophic respiration and autotrophic respiration together and then subtract that value from gross primary productivity, then you have a more refined estimate of ecosystem carbon storage than NEE.
