Bio Practice Exam 28 Questions with Verified Answers Why did DNA evolve to be the carrier of genetic information in cells as opposed to RNA? - CORRECT ANSWER the hydrogen at the 2' position in the deoxyribose of DNA makes it more stable than RNA In the mismatch repair process, enzyme complexes replace bases that were incorrectly inserted into the newly synthesized DNA strand. To function, they must be able to distinguish between the parent DNA strand and the new strand. How is this accomp...

AC-HPAT Biology Questions With 100% Correct Answers. Pancreas and Type 1 diabetes The pancreas is the organ that produces insulin, and it plays a major role in regulating blood glucose levels. Type 1 diabetes occurs when the pancreas does not make enough or any insulin. How does insulin work in diabetes? Insulin pumps are small, computerized devices that mimic the way the human pancreas works by delivering small doses of short acting insulin continuously (basal rate). The device also is ...

Biology 1000 – Principles of Biology ( BioS 115 Core II: Genetics) Exam Study Guide Questions With Answers. Explain the concepts of penetrance and expressivity Penetrance is the percentage of cases in which a certain phenotype is expressed. There are two types: i. Complete Penetrance: when 100% is correlated to the genotype. So, all express the same thing. ii. Incomplete: this is when some are identical, and others are different. Penetrance= # with genotype showing phenotype x 100 # wit...
