Describe the steps of protein synthesis, beginning with the attachment of a messenger RNA molecule to the small subunit of a ribosome and ending generalized with the release of the polypeptide from the ribosome. Explain the evolutionary mechanisms that can change the composition of the gene pool.
Include in your discussion a sample cross es sufficient to verify your proposed pattern. In a laboratory population of diploid, sexually reproducing organisms a certain trait is studied.
This disorder occurs with equal frequency in males and females. Describe the production and processing of a protein that will be exported from a eukaryotic cell.
What would be the effects of a substitution in one of the nucleotides? The different results you would expect if a mutation occurred at the recognition site for enzyme Y.
Explain the mechanisms that lead to evolutionary change.
Describe the special relationship between the two terms in each of the following pairs. Genetic variation is the raw material for evolution. Explain why each of these features is necessary. After four generations, the following results were obtained. Describe how scientists use each of the following as evidence for evolution.
Describe the process of speciation.
Explain how these alleles are distributed by the process of meiosis to gametes. Bacterial resistance to antibodies. Select one of the criteria stated above and describe experimental evidence used to determine that DNA is the hereditary material.
This trait is determined by a single autosomal gene and is expressed as two phenotypes.
Explain the purpose of each step of your procedure. By using the techniques of genetic engineering, scientists are able to modify genetic materials so that a particular gene of interest from one cell can be incorporated into a different cell.
Include in your discussion the factors that may contribute to the maintenance of genetic isolation. In rabbits the white color is due to a recessive allele, w, and the agouti is due to a dominant all, W. A new population was created by crossing 51 pure breeding homozygous dominant individuals with 49 pure breeding homozygous individuals.
