Question

Consider all the cells in your body, or that of a donkey, iguana or sparrow. Which one of these statements is the most accurate?

Select one: a. The DNA in all cells of an individual is the same, and their function and protein production is identical

b. The DNA in all cells of an individual is the same, BUT their function and protein production differs depending on location and need

c. The DNA in all cells of a specific organ in an individual is the same, but in that same individual the DNA in kidney cells will differ from the DNA in bone cells, etc.

d. The DNA in each cell differs, as does the type of protein produced.

Answer 1

B is the answer.

Explanation:

DNA is found to be same in all cells of the body of an organism. Because the dame nucelotide sequence is found in the genome of each cells of the body.

Yet the different functions are found in the different cells. Because each cell has different genes which undergoes the transcription because of presence of different transcription factors. There are different activator and repressor in different cells. These lead to produce different function in kidney, bone and stomach cells.
