Question
28. When studying living cells in a laboratory, rescarchers sometimes use drugs as a way to make cells remain at a particular stage of the cell cycle A drug that inhibits cytokinesis would leave cells arrested at which phase in the cell cycle? A) Interphase B) Telophase C) Anaphase D) Prophase E) Metaphase 29. An epigenetics modification is where: A) The DNA sequence of a gene is changed, altering gene expression B) A chemical modification (ie methylation) of DNA occurs that alters gene expression C) Gene expression is permanently changed over the course of many generations D) Both A and C E) Both B and C 30. A very rare dominant allele that causes the little finger to be bent has a penetrance value of 80% This means that? A) 80% of the total population does not have a bent little figure B) 80% of all heterozygotes carrying the allele will have a bent little finger C) 80% of the total population carries the allede for bent little finger D) 80% of all homozygous individuals carrying the allele will have a bent little finger 31. Mendel's Law of Independent Assortment can be explained by the random alignment of bivalents during metaphase of A) Meiosis I B) Meiosis II C) Mitosis
