Results from our forumRe: Theories - Origin of Life... Major evolutionary change to the genome occurs by the amplification and rearrangement of pre-existing modules. Old genomic systems are disassembled ... � Major alterations in the content and distribution of repetitive DNA elements results in a reformatting of the genome to function in novel ...

Re: Gene Rearrangement and EvolutionThe overall DNA content does not change, although with "jumping genes" (Transposons) mutations can occur and change the DNA. Whether or not changing the sequence of genes in DNA is classed as changing the DNA would depend ...

Gene Rearrangement and EvolutionClear this up for me: To say genes rearrange in a cell is to say a person's DNA changes. True or false? Also, can someone give me some info on "jumping genes"? I've been trying to decide if they really are a factor in evolution. I want to make sure I ...

Re: When do mutations occur?... during translation. Think about UV radiation which can cause lesions in DNA which block the RNA polymerase thus, no transcription which means absence ... the mutation occur when the UV photon hits the bases and causes a rearrangement of covalent bonds (e.g. thimine dimerization)? The effect on ...
