Question

What activity is accomplished using the genetic code?

cells make proteins.
RNA molecules are copied before mitosis begins.
mRNA molecules are transcribed to form tRNA.
polypeptides are made into mRNA.

Answer 1

Proteins are synthesized using the genetic code through the process of translation. mRNA molecules are transcribed from DNA and then interact with the cellular machinery to synthesize proteins. Each codon in the mRNA sequence codes for a specific amino acid.

Step-by-step explanation:

Proteins are synthesized using the genetic code through the process of translation. The genetic code is a correspondence between mRNA codons and amino acids. mRNA molecules are transcribed from DNA and then interact with the cellular machinery to synthesize proteins. The mRNA sequence is read in sets of three bases known as codons, and each codon codes for a specific amino acid.

Answer 2

(A) Cells make proteins
Proteins are composed of amino acids. Proteins are made in a process called translation, in which the cell commands.
(B) RNA molecules copied before mitosis begins
DNA molecules are copied before mitosis, not RNA.
(C) mRNA molecules are transcribed to form tRNA
DNA is used as template to form both mRNA and tRNA in a process called transcription.
(D) polypeptides are made into mRNA
mRNA is the template used to make polypeptides in a process called translation.

Therefore, A is the right answer.
