Question

DNA, in the nucleus carries the genetic code for making proteins in ribosomes. In the diagram, B, represents the proteins produced. DNA cannot leave the nucleus to carry the genetic information to the ribosome where proteins are produced. How does the genetic code get from the nucleus to the ribosome? What does A represent?

A) RNA
B) chromosomes
C) ribosome
D) translation

Answer 1

A) RNA

Step-by-step explanation:

The genetic code in DNA is copied by RNA which can leave the nucleus and carry the code to the ribosome. mRNA copies the DNA code. tRNA brings amino acids to the ribosome and proteins are made.

Answer 2

A. RNA

Step-by-step explanation:

The image shows the unidirectional flow of genetic information from DNA to proteins. DNA is genetic material and serves as a template for synthesis of RNA. The mature mRNA leaves the nucleus and enter cytoplasm to join with ribosomes. The mRNA serves as a template for protein synthesis. hence, mRNA serves to carry the genetic information from the nucleus to ribosomes.
