Topic Three Protein Synthesis Flashcards
(13 cards)
Proteins
The work horse of the cell
Amino acid
The polymer of a protein
Gene
A section of nucleotide chains
Polypeptide
Unfolded protein
mRNA
Messenger RNA
tRNA
Transfer RNA which takes amino acids to the ribosome where they are joined into a chain to form polypeptide bond
rRNA
Makes up the ribosomes
Protein synthesis
The process of making proteins occurs in two steps
Transcription
mRNA picks up the code from the dna template strand and takes it from the nucleus to the ribosome in the cytoplasm
Translation
The instructions (mRNA) are read by tRNA joins the amino acid in the right order in the ribosome
Codon
3 bases on mRNA strand
Anticodon
3 bases at the bottom of each tRNA
Central dogma
The main part
