The code is made from DNA and is a sequence of bases which code for amino acids and their sequence determing what proteins are made.
Genes- length of DNA that codes for one of more polypeptides in a cell.
Polypeptide- Sequence of amino acids which are joned by peptide bonds.
Genome- Entire DNA sequence of an organism.
Protein- Large polypeptide around 100 = amino acids (Collagen, haemoglobin, antigens)
Triplet code- codons for one amino acid
Degenerate so all amio acids have more than one code.
Widespread- The basic DNA is the same in all organisms its how we interpretate them. One gene that makes a fish glow can make a mouse glow.
Transciption and translation
- Takes place in nucleus
- mRNA is produced
- RNA polymerase and heliase are used in the process
- Unwinds/unzips DNA
- mRNA is complementary to the template strand
- Takes place in ribosomes
- Produces proteins
- tRNA is used to make the protein each with a corresponding anticodon
- Uses the mRNA strand
