... Proteins are complex molecules which control most aspects of cell biology. Constructed of small subunits called amino acids. There are 20 types of amino acid. Assembeled by ‘reading’ (or translating) the DNA sequence. Every set of 3 bases (e.g. ATG) corresponds to an amino acid. So a protein is buil ...

... an organism consists of a very long sequence of four different nucleotides with bases A, C, G, T. Genomic DNA is a double-stranded helix comprised of two complementary strands, held together by A-T and C-G base pairs. The entire genome is replicated by DNA polymerases (a protein) and passed on to da ...

... The information in DNA must be decoded. The two strands of the double helix are made of bases and these are in a specific order. To make a protein that can leave the nucleus, the DNA makes a copy of itself. This copy is called messenger RNA. The mRNA shuttles the code out of the nucleus where smal ...

Point mutation



A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
