Question

which two statements correctly relate dna, rna, and amino acids? a. rna is used to build an amino acid sequence during translation. b. dna is used as a template to form rna during transcription. c. rna is used as a template to form dna during translation. d. dna is used to build an amino acid sequence during transcription.

Explanation:

• For option A: During translation, mRNA (a type of RNA) is read by ribosomes, and tRNA brings amino - acids. The sequence of mRNA (RNA) determines the amino - acid sequence. So, RNA is used to build an amino - acid sequence during translation.
• For option B: During transcription, DNA is used as a template to form RNA. RNA polymerase reads the DNA strand and synthesizes a complementary RNA strand.
• For option C: It is DNA that is used as a template for RNA synthesis during transcription (not RNA as a template for DNA). Reverse - transcription (RNA to DNA) is a special process in some viruses (like retroviruses) but not the normal transcription process.
• For option D: DNA is not directly used to build an amino - acid sequence during transcription. Transcription is about making RNA from DNA.

Answer:

A. RNA is used to build an amino acid sequence during translation.
B. DNA is used as a template to form RNA during transcription.
