Insertions

Insertion sequence

mobile nucleotide sequences that occur naturally in the genomes of bacterial populations. When inserted into bacterial dna, they inactivate the gene concerned, when they are removed the gene regains its activity. Closely related to transposons and range in size from a few hundred to a few thousand bases, but are usually less than 1500 bases.

... of the ones you said you agreed with. The term mutation can refer to any process that changes the genetic information in the genome, including DNA insertions, deletions and rearrangements. And as already discussed ‒ rearrangements are random as well. Or to avoid giving the wrong impression, they ...

Re: Theories - Origin of Life

... Natural selection is NOT random! The term mutation can refer to any process that changes the genetic information in the genome, including DNA insertions, deletions and rearrangements. Genetic variation is generated continuously by the mutational process, but its persistence in the genome is ...

Re:

The length doesn't matter much. You can easily do deletions or insertions with homologous recombination. During recombination when: Original Segment A = T-A-T-C-T-T-T-T- A-G-G-T-A -G-C-A Engineer Segment B = T-A-T-C-T-T-T-T -C-C-C-C-C- G-C-A The sequences ...

Mutation rate

... am writing a program involving the rates of specific mutations, and I was wondering if anyone had a good source for the rates of point mutations, insertions, and deletions in humans. Thank you very much.
