I can do all things through christ who strengthens me!

(rRNAs) ribosomal RNA’s

form the structural and catalyatic core of the ribosomes - translate mRNAs into protien

(tRNAs) Transfer RNA’s

act as adaptors that select specefic amino acids and hold them in place on a ribosome for their incorporation into proteins

(miRNAs) microRNAs

serve as key regulators of eukaryotic gene expression

(siRNAs) Small interfering RNAs

Provide protection from viruses and proliferating transposable elements

(mRNAs) messenger RNAs

code for proteins

transcription

the process by which cells read out the instructions in their genes/ written in the language of nucleotides

DNA is transcribed into RNA via
