DNA is considered the blueprint of life, yet in eukaryotic organisms, such as humans, it never leaves the nucleus. Which of the following is the best explanation for how DNA provides the code for physical traits and characteristics, even though it never enters the cytoplasm? * what's the answer?? D:

A. The DNA in the nucleus is transcribed into mRNA, which can then leave the nucleus and be translated at the ribosome into proteins, which make up physical traits and characteristics.

B. Under the right conditions, DNA turns into RNA so it can leave the nucleus, then it is translated into proteins which make up physical traits and characteristics.

C. The DNA in the nucleus is translated into proteins, which are able to leave the nucleus and enter the cytoplasm, where transcription of mRNA can occur. The mRNA then makes up the physical traits and characteristics.

D. Inside the nucleus, DNA is transcribed into mRNA, which is then translated into proteins. These proteins can then leave the nucleus and make up physical traits and characteristics.
