Question

1. what is the role of mrna in protein synthesis? * 2 points

a. to carry amino acids to the ribosome
b. to carry the genetic code from dna to the ribosome
c. to form the structure of the ribosome
d. to fold proteins into their functional shape

1. what is a codon? * 2 points

a. a three - nucleotide sequence on mrna that codes for an amino acid

Explanation:

1. mRNA (messenger RNA) is transcribed from DNA and travels to the ribosome to provide the template for protein - synthesis. tRNA (transfer RNA) carries amino acids to the ribosome, rRNA (ribosomal RNA) forms part of the ribosome structure, and chaperone proteins help in protein folding.
2. A codon is a three - nucleotide sequence on mRNA that corresponds to a specific amino acid during translation.

Answer:

1. B. To carry the genetic code from DNA to the ribosome
2. A. A three - nucleotide sequence on mRNA that codes for an amino acid
