Cellular Control

Cellular Control . You should be able to: ( a) state that genes code for polypeptides, including enzymes; (b) explain the meaning of the term genetic code ; (c) describe, with the aid of diagrams, the way in which a nucleotide sequence codes for the amino acid sequence in a polypeptide;

Mutation and DNA

Mutation and DNA. Mutation = change(s) in the nucleotide/base sequence of DNA; may occur due to errors in DNA replication or due to the impacts of chemicals or radiation to the DNA molecule Mutation may result in coding sequences for new amino acids in proteins or not!.

MUTATIONS: - A source of variation

MUTATIONS: - A source of variation. A change in the nucleotide base sequence of the DNA or a change in the structure or number of chromosomes. Mutagens. Mutagens cause mutations which are mistakes in the base sequence of the DNA. (If you change the recipe, you change the cake).

Genetic code:

Genetic code: Def . Genetic code is the nucleotide base sequence on DNA ( and subsequently on mRNA by transcription) which will be translated into a sequence of amino acids of the protein to be synthesized. The code is composed of codons
