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.
As it seems, point mutations are of few types, but the result is always a change in a single nucleotide. The number of the nucleotides is not changed, but the structure will be different; hence, the function of the gene may be altered. What is the difference between Frameshift Mutation and Point Mutation? â¢ The frame of the DNA strand is shifted one way or the other in a frameshift mutation, whereas point mutations do not change the frame of the DNA strand. â¢ The gene structure and the number of nucleotides are changed in frameshift mutations while point mutations cause only the structure of a gene.
