Unit 1 - KA3 - Control of Gene Expression Flashcards
A chain of amino acids linked together by peptide bonds
Polypeptide
Bonds that join different parts of a polypeptide chain together to help create the three dimensional structure of the protein
Peptide
The complete genetic information contained in a cell.
Genotype
The 20 subunits that make up a polypeptide.
Amino acids
The bond that joins two amino acids together.
Peptide
The final overall shape that a protein takes based on how it is folded and how the polypeptide chains in it interact.
3 Dimensional
The physical characteristics of an organism.
Phenotype
-shaped proteins involved in the immune response which bind specifically to particular antigens.
Antibody
Oxygen transporting protein contained in red blood cells.
Haemoglobin
Protein molecules which catalyse specific chemical reactions.
Enzymes
Proteins that form the shape of all organelles and cells in the body.
Structural
Enzyme required for transcription
RNA polymerase
First RNA transcript made before processing
Primary RNA transcript
Section of RNA removed to create the mature RNA transcript.
Introns
Triplet of bases on a tRNA molecule which determine the particular amino acid joined onto the extending polypeptide chain.
Anti-codon
