Include in your answer a discussion of how the different types of RNA function in this process. Explain how these alleles are transmitted by the process of mitosis to daughter cells.

What would be the effect of a deletion or an addition in one of the DNA nucleotides? After four generations, the following results were obtained. 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.

Describe the production and processing of a protein that will be exported from a eukaryotic cell. Indicate the conditions under which allelic frequencies p and q remain constant from one generation to the next. Describe the biochemical composition, structure, and replication of DNA. An organism is heterozygous at two genetic loci on different chromosomes.

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. 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.

Unit 7 Evolution, Population Genetics, Speciation Explain why each of these features is necessary. Describe the operon hypothesis and discuss how it explains the control of messenger RNA production and the regulation of protein synthesis in bacterial cells. Birds of prey and DDT. Labeled diagrams that are explained in your answer may be useful.
