Question

Describe the function of each of the following in protein synthesis: rrna,mrna,trna

Answer 1

mRNA carries genetic information, tRNA brings amino acids, rRNA forms ribosomes.

Step-by-step explanation:

The three major types of RNA molecules involved in protein synthesis are:

1. mRNA (messenger RNA): carries the genetic information from DNA to the ribosomes in the cytoplasm. It serves as a template for protein synthesis by providing the sequence of codons.
2. tRNA (transfer RNA): brings the amino acids to the ribosomes during protein synthesis. Each tRNA molecule has an anticodon that complements the codon on the mRNA, ensuring the correct association of amino acids.
3. rRNA (ribosomal RNA): combines with proteins to form ribosomes, which are the site of protein synthesis. It also has enzymatic activity and catalyzes the formation of peptide bonds between amino acids.

Answer 2

mRNA is transcribed from DNA. The nucleotide in mRNA code for amino acids. tRNA translates the mRNA sequence into an amino acid sequence so proteins can be made.
