Protein Synthesis

• m-RNA migrates to cytoplasm or ER
• m-RNA serves as "blueprint" for protein synthesis
• t-RNA brings individual amino acids to Ribosome

• How do you spell "stop" or "go" in m-RNA?

Proteins made in the Nucleus too?!

Ribosomes

The Ribosomes are made in the nucleus of r-RNA.
The small 30s and large 50s subunits fit together and translate the m-RNA sequence into protein primary structure.

"The regulation of gene expression (on-off!) through various cellular processes including DNA methylation, histone acetylation, and RNA interference."

• Fertilization is not the only means for the transfer of genetic information (DNA)
• 'Horizontal Gene Transfer' link 'vector'
• Bacteria insert DNA into host organisms w/ plasmid
