Protein Synthesis

Protein synthesis is here to make new proteins. Proteins must be fully formed and functional for traits to be correctly expressed.

Transcription happens in the nucleus. This is when the DNA is used to make mRNA. RNA is single stranded and uses uracil as a substitute for thymine. mRNA leaves the nucleus through the membrane to go to its next step.
Translation happens in the ribosomes. This is when the mRNA and tRNA work together to make amino acid chains, which in turn make proteins. mRNA binds to a ribosome and tRNA transports the amino acid to the mRNA. Every codon, made up of three bases on the mRNA, one amino acid is brought in. The amino acids form a polypeptide (protein).
Gene expression is when genes are expressed from the new proteins. The environment can also activate certain genes.
