Chapter 21, Problem 21.128AQAP

Interpretation Introduction

Interpretation:

Rib nucleic acid (RNA) is a type of molecules is the mode of a long chain of nucleotide units.

A nucleotide consists of a nitrogenous base, ribose sugar, and phosphate.

There are main types of RNA each enclosed by its own types of gens.

(1) mRNA (Messenger RNA)

(2) t RNA (transfer RNA)

(3) r RNA (Ribosomal RNA)

Concept introduction:

mRNA (messenger RNA): it is the most heterogeneous among RNA. It carries genetic code copy during transcription from the DNA. It acts as a template during protein synthesis.

tRNA (transfer RNA): it is the smallest of the $3-$ types of RNA. Its main function is the transfer of amino acid during protein synthesis.

r-RNA (Ribosomal RNA): this RNA is found in ribosomes. It makes up the very large percentage of RNA in a cell. About $80\%$. This act as the site of protein synthesis and has the enzymes needed during this process. Ribosomal RNA then links amino acids together to form proteins.
