Gene mutations vs. Chromosomal mutations. Review the process of Recombination . Think of mistakes that can happen, especially with the Holliday structure, and with supposedly homologous base pairing. Review DNA replication. Note that many different kinds of mutation can prevent mRNA transcription, resulting in the same phenotype.
Successive mutations play a major role in the appearance and progression of malignant tumors.
Chromosomal abnormalities in number and structure are often seen in tumor cells. The magnitude of the mutation may have no correlation with the magnitude of the phenotype. Example, Sickle-cell anemia. G 5' You should find two ways to do it. Write the protein, using the genetic code in your text.
