Genes and proteins
DNA- Deoxyribonucleic Acid- Nucleic acid that carries genetic information in cell and consists of 2 complementary chains of nucleotides wound in a double helix.
Organic bases- A- adenine, T- thymine, C- cytosine, G- guanine – AT, CG,
In RNA U-uracil replaces T
RNA- group of single strand nucleic acids including mRNA (messenger RNA) that is necessary for transcription and translation. (AU, CG)
Codon- 3 adjacent nucleotides in DNA and mRNA that code for amino acid in a protein.
Mutation- a change in DNA sequence of a gene.
Protein- large molecule consisting of one or more chains of amino acids (polypeptides)
Amino acids: building blocks of protein molecules.
Mitosis- nuclear division characterized by chromosome replication and formation of two identical daughter nuclei.
Chromosome- structures of DNA and proteins in the nucleus of cells where genes are located.
