1. Explain BRIEFLY whether each of the following conditions will increase or decrease the chance of cancer: a. a mutation in the promoter region of a tumor suppressor gene that results in that gene being overexpressed (assume that the cell is heterozygous for the mutation) b. a mutation in the promoter region of a protooncogene that results in that gene being overexpressed (assume that the cell is heterozygous for the mutation) c. a homozygous mutation that completely eliminates the coding region of a protooncogene

Transcribed Image Text:1. Explain BRIEFLY whether each of the following conditions will increase or decrease the
chance of cancer:
a. a mutation in the promoter region of a tumor suppressor gene that results in that gene
being overexpressed (assume that the cell is heterozygous for the mutation)
b. a mutation in the promoter region of a protooncogene that results in that gene being
overexpressed (assume that the cell is heterozygous for the mutation)
c. a homozygous mutation that completely eliminates the coding region of a protooncogene
d. a homozygous mutation that completely eliminates the coding region of a tumor
suppressor gene
e. a heterozygote where one allele is the mutant allele described in (c), the other allele
being wild type
f.
a heterozygote where one allele is the mutant allele described in (d), the other allele
being wild type
