Web(i) single gene mutations; (4) (ii) chromosome mutations (3) (2015) 1. (single gene) mutations are random changes in DNA sequences/genes/ alleles/the genome 2. single gene mutation name AND description substitution – base/base pair/ nucleotide is replaced/substituted by another insertion – base/base pair/ nucleotide is added/inserted WebIn eukaryotic cells, the first stage of gene expression control occurs at the epigenetic level. Epigenetic mechanisms control access to the chromosomal region to allow genes to be turned on or off. These mechanisms control how DNA is packed into the nucleus by regulating how tightly the DNA is wound around histone proteins.
