What would be the effects of a substitution in one of the nucleotides? Unit 7 Evolution, Population Genetics, Speciation The different results you would expect if a mutation occurred at the recognition site for enzyme Y. Begin with the separation of the messenger RNA from the DNA template and end with the release of the protein at the plasma membrane.
The mechanism of action of restriction enzymes. Explain how the principles of gel electrophoresis allow for the separation of DNA fragments.
Explain how each of the following deviates from these conclusions. Convergent evolution of organisms and Australia.
Include in your discussion the factors that may contribute to the maintenance of genetic isolation. The arrows indicate reaction sites for two restriction enzymes enzyme X and enzyme Y. Describe how scientists use each of the following as evidence for evolution.
Include in your discussion a sample cross es sufficient to verify your proposed pattern. Describe a procedure by which this can be done.
Discuss how recombinant DNA techniques may be used to correct a point mutation. A portion of specific DNA molecule consists of the following sequence of nucleotide triplets. Calculate, showing all work, the frequencies of the alleles and the frequencies of the genotypes in a population ofrabbits, of which 25, are white and 75, are agouti.
A new population was created by crossing 51 pure breeding homozygous dominant individuals with 49 pure breeding homozygous individuals. In rabbits the white color is due to a recessive allele, w, and the agouti is due to a dominant all, W.
