Bio Exam 3 Questions and Answers 100% Pass What did Griffith discover in his experiment involving bacteria with capsule (S) and non-capsule (R) strains, and what molecule did Avery, MacLeod, and McCarty identify as responsible for this phenomenon? Griffith observed that DNA could transform bacteria, demonstrating for the first time that genetic material can be transferred through a process called transformation. The S-strain, with a polysaccharide capsule, is protected from the immune...

AC-HPAT Biology Prep Questions and Answers Already Passed Most of the cell membrane's specific functions are controlled by: Proteins Alcoholic Fermentation is a form of: Anaerobic Respiration Phagocytosis is a form of: Endocytosis What is a pyruvate? Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. One molecule of glucose breaks down into two molecules of pyruvate, which are then used to provide furth...

Honors Biology Semester 2 Final Exam with Complete Solutions What is the role of helicase in DNA replication? Helicase unwinds the DNA double helix by breaking hydrogen bonds between base pairs, allowing replication to begin. How does complementary base pairing ensure accuracy during DNA replication? Complementary base pairing (A with T, C with G) ensures that each new strand is an exact copy of the original template. What is a codon, and how is it related to DNA? A codon is ...
