Q1. Each allele of single gene in a diploid cell during the G1 phase is present as part of a single (double-stranded) molecule. The Drosophila genome is approximately 150 Mb. which means that single haploid genome (one allele of each gene) would be 150,000,000 base pairs. Recalling that Avogadro’s number […]

1. In Grave’s Disease, hyperthyroidism is produced by an IgG that causes prolonged activation of the TSH receptors and results in excessive secretion of T3 and T4.  Explain why the negative feedback mechanism does not work in this disease. Reference an internet source (URL) or book. 2. Chromatographic assay reveals […]

Q1. Using the knowledge of DNA replication, describe the mechanisms in place for preventing mistakes during the process. Also discuss how potential mistakes can happen? What would be the consequences of such mistakes during the process? Q2. The research team used setup to learn the incorporation of labelled nucleotides into […]
