Question

_ Which three statements correctly describe the roles or RNA molecules in the process of transcription and translation in animal cells?


a. Small RNA molecules in the RNA polymerase catalyze the formation of phosphodiester bonds between nucleotides in the growing messenger RNA

b. Messenger RNA molecules carry genetic information from the gene in the nucleus to the ribosome in the cytoplasm.

c. Transfer RNA molecules carry the appropriate amino acid to the growing polypeptide

d. Genomic RNA molecules store genetic information and transmit it to an individual’s offspring

e. Ribosomal RNA molecules function in the assembly of the ribosome-mRNA complex and in the formation of peptide bonds between amino acids in the growing polypeptide.

Answer 2

The three statements that correctly describes the role of RNA in transcription and translation are as follows:

1. Messenger RNA molecules carry genetic information from the gene in the nucleus to the ribosome in the cytoplasm.
2. Transfer RNA molecules carry the appropriate amino acid to the growing polypeptide.
3. Ribosomal RNA molecules function in the assembly of the ribosome-mRNA complex and in the formation of peptide bonds between amino acids in the growing polypeptide.

ROLE OF RNA:

• Transcription is the process whereby a mRNA molecule is synthesized from a DNA template while translation is the process whereby an amino acid sequence is synthesized from mRNA.

• Ribonucleic acid (RNA) is one of the two nucleic acids that performs varying functions in the processes of transcription and translation. There are three types of RNA namely: mRNA, tRNA, rRNA.

1. mRNA or messenger RNA molecules carry genetic information from the gene in the nucleus to the ribosome in the cytoplasm.
2. tRNA or transfer RNA molecules carry the appropriate amino acid to the growing polypeptide.
3. rRNA or ribosomal RNA molecules function in the assembly of the ribosome-mRNA complex and in the formation of peptide bonds between amino acids in the growing polypeptide.
