RNA is\u00a0a type of\u00a0nucleic acid similar to DNA<\/a>.\u00a0 However there are three key differences between RNA and DNA<\/a>:<\/p>\n

1.\u00a0 \u00a0The sugar in RNA is ribose, not the deoxyribose in DNA<\/a> (as we previously learned).
\n2.\u00a0 \u00a0The base uracil is present in RNA instead of thymine.
\n3.\u00a0 RNA is a single stranded molecule, DNA<\/a> is double stranded.<\/p>\n

Three main\u00a0types of RNA exist all involved in protein synthesis<\/a>.<\/p>\n

Ribosomal RNA or rRNA <\/strong>is found in the ribosomes,\u00a0where protein synthesis <\/a>takes place. Each ribosome is a complex consisting of about 60% ribosomal RNA (rRNA) and 40% protein.<\/p>\n

Messenger RNA or mRNA <\/strong>carries a copy of the\u00a0information (or transcript)\u00a0from DNA in\u00a0the nucleus to the ribosomes.\u00a0 It is this transcript that is used in protein synthesis<\/a>.<\/p>\n

Transfer RNA or tRNA <\/strong>delivers amino acids\u00a0to the ribosome, where they are inorporated into the growing protein chain.\u00a0 There is a different tRNA for each type of amino acide used in protein synthesis<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
