Answer #1

A gene is a section of DNA that controls a certain trait. Genes can mutate and take on different forms one of these forms is an allele.

Alleles are alternate versions of a gene and they can be found at a fixed spot on a chromosome.

For example, if a gene coding for a particular enzyme is mutated, then there would be two alleles of the gene: the 'normal' form and the mutated form. The proteins encoded would probably also be slightly different, for instance the mutated allele might code for the same enzyme but in a slightly different shape.

4.A child is born with a single functional allele of a tumor suppressor gene. At the age of five the remaining normal allele is lost through a point mutation. As a result, the ability to inhibit cell cycle progression until the cell is ready to divide is lost. Which of the following neoplasms is most likely to arise via this mechanism? A Breast ductal carcinoma B Pulmonary small cell anaplastic carcinoma c Ocular retinoblastoma D Cerebral astrocytoma E Chronic myeloid...

Assume that for a given gene a mutation creates an allele that functions as a dominant negative. The gene codes for a protein that forms a tetramer (4) within the cell. If at least one of the subunits has the mutant structure the entire protein is inactivated. For a heterozygous individual, what percent of the tretramers present in the cell will be inactive?
