WebThe cystic fibrosis transmembrane conductance regulator (CFTR) is defective in cystic fibrosis (CF). This protein is a channel that sits on the surface of cells and transports chloride and other molecules, such as bicarbonate. The gene that encodes the CFTR protein, which is also called CFTR, is located on chromosome 7. Mutations in this gene lead to CF. … WebCancer is the result of unchecked cell division caused by a breakdown of the mechanisms that regulate the cell cycle. The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Faulty instructions lead to a protein that does not function as it should.

WebThe one gene, one enzyme hypothesis is the idea that each gene encodes a single enzyme. Today, we know that this idea is generally (but not exactly) correct. Sir Archibald Garrod, a British medical doctor, was the first to suggest that genes were connected to enzymes. Beadle and Tatum confirmed Garrod's hypothesis using genetic and biochemical ... WebLike DNA, RNA is made up of nucleotide consisting of a 5-carbon sugar ribose, a phosphate group, and a nitrogenous base. However, there are three main differences between DNA … WebDefective p53 could allow abnormal cells to proliferate, resulting in cancer. As many as 50% of all human tumors contain p53 mutants. In normal cells, the p53 protein level is low. DNA damage and other stress signals may trigger the increase of p53 proteins, which have three major functions: growth arrest, DNA repair and apoptosis (cell maryland childcare admin

Web43. Explain why half of DNA is replicated in a discontinuous fashion. Replication of the lagging strand occurs in the direction away from the replication fork in short stretches of DNA, since access to the DNA is always from the 5’ end. This results in pieces of DNA being replicated in a discontinuous fashion.
