This document summarizes the key components and functions of ribonucleic acid (RNA). It discusses that RNA is formed through transcription using the enzyme RNA polymerase. RNA contains a ribose sugar, phosphoric acid, and one of four nitrogenous bases. The document then describes the three main types of RNA: messenger RNA (mRNA) which carries genetic information for protein synthesis, transfer RNA (tRNA) which provides attachment sites for mRNA on ribosomes, and ribosomal RNA (rRNA) which helps in translation. tRNA carries amino acids to ribosomes and attaches to mRNA codons through complementary base pairing to facilitate protein synthesis.

U, C, A , G

4. m RNA
t RNA
r RNA

5. Single-stranded RNA
IT is complementary to one of the DNA strands of a gene.
Contain genetic information in the form of codons.
Ribosome binds on m RNA during protein synthesis.
Provide site for attachment of tRNA anticodons

6.  Part of ribosome
 Provide attachment site for mRNA on ribosome
 Help in translation

7.  Carry amino acids to the ribosome
 Its anticodons attaches with codons of mRNA

8.  Attachment of amino acid with t RNA
 Formation of aminoacyl t RNA
 Aminoacyl t RNA binds with mRNA
