A. Adds nucleotides to the growing strand DNA B. Stabilizes single-stranded DNA until it can be used as a template C. Enzymes that untwist the double helix at the replication forks D. Corrects over winding of the uncoiling DNA strand Question 8 What is the purpose of helicase? A. Corrects over winding of the uncoiling DNA strand B. Enzymes that untwist the double helix at the replication forks C. Stabilizes single-stranded DNA until it can be used as a template D. Adds nucleotides to the growing strand DNA Question 9 What is a gemetic mutation? A. A disease B. A mistake in the replication of a DNA molecule C. X-Men are mutations D. A faulty ribosome that makes proteins incorrectly Question 10 3 / 4 pts Tell me what the Law of Segregation means in gamete formation. Do not just restate the law, tell me what it means. Your Answer: The law of segregation means that during the formation of sperm and egg cells the two alleles for a trait separate from each other. This makes sure that oSspring inherit one allele from each parent. Question 11 3 / 4 pts Tell me what the Law of Independent Assortment means in gamete formation. Do not just restate the law, tell me what it means. Your Answer: The law of independent assortment means that diSerent traits are passed on to gametes independently. The inheritance of one trait doesn't aSect the inheritance of another trait.
