Question

DNA is considered the blueprint of life, yet in eukaryotic organisms, such as humans, DNA never leaves the nucleus. Which of the following is the best explanation for how DNA codes into physical traits and characteristics, even though it never enters the cytoplasm?

Answer 1

Answer:

The first one

Explanation:

This is just Central Dogma. DNA (deoxyribonucleic acid) is transcripted into mRNA which goes to the Ribosomes where it is turned into polypeptides/protiens which code the body.

Answer 2

DNA is a molecule made up of  Deoxyribonucleic acid that is composed of two chains that coils are around themselves and form the double helix.

• Within eukaryotic cells, DNA is organized into a strong structure called as chromosomes. These are duplicated in the cell formation process. Most organisms store their DNA in the cell nucleus.

• DNA is a long polymer made of repeating units. DNA is capable of coiling into tight loops and other shapes. As the genetic information is held within genes the genome encodes protein.

• Thus the DNA is a nucleus and can be transcribed in the mRNA which later eaves the nucleus and forms proteins. Hence the option A is correct.
