Cytosines in single-stranded DNA deaminate to uracils at 140 times the rate for cytosines in double-stranded DNA. If resulting uracils are not replaced with cytosine, C to T mutations occur. These facts suggest that cellular processes such as transcription that create single-stranded DNA should promote C to T mutations. We tested this hypothesis with the Escherichia coli tac promoter and found ...

A silent mutation is a mutation that occurs within the DNA sequence, but does not alter the amino acid sequence. Silent mutations can occur in introns, which are spliced out before translation. Finally, a frameshift mutation is an insertion or deletion of a nucleotide sequence that alters the reading frame of the gene.

  24. Sep 18, 2020 · Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes. Genetic variations can arise from gene mutations or from genetic recombination (a normal process in which genetic material is rearranged as a cell is getting ready to divide).
  25. Evolution affects a population when mutations change the genetic variety of individuals. As a mutation spreads through the population by reproduction and inheritance it changes the genome of the species. As more and more mutations are acquired in the population, speciation can eventually occur.
