MourningBands added 2 new photos. Honoring Those that Answered the Call. When people answer the call of public service with their lives, as far as I'm concerned, that's the gold standard. That was my thought when I brought these pieces together, and my thought each and every time one of them falls in the line of duty.
Best Answer: A mutation is a change in DNA. Genetic recombination can apply to two things: crossing-over between homologous chromosomes or recombining of traits when gametes fuse during fertilization. They all contribute to evolution because they result in a new organism with a new combination of characteristics. This new combination of characteristics is subjected to natural selection.
Homologous recombination is a type of genetic recombination in which nucleotide sequences are exchanged between two similar or identical molecules of DNA. It is most widely used by cells to accurately repair harmful breaks that occur on both strands of DNA, known as double-strand breaks.Homologous recombination also produces new combinations of DNA sequences during meiosis, the process by which eukaryotes make gamete cells, like sperm and egg cells in animals.t is most widely used by cells to accurately repair harmful breaks that occur on both strands of DNA, known as double-strand breaks.
