BIOL 112 Final Exam Learning Goals (Starts at mutations) 100% Pass Identify the different types of point (base substitution) mutations; missense, nonsense and silent mutations. POINT MUTATION: = A change in a single nucleotide Types: 1) Silent Mutation = When the redundancy of the genetic code kicks in and the change in that single nucleotide results in the same amino acid produced as the original code. 2) Missence Mutation = When the change in a single amino acid changes the am...

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...

Identify the different types of point (base substitution) mutations; missense, nonsense and silent mutations. POINT MUTATION: = A change in a single nucleotide Types: 1) Silent Mutation = When the redundancy of the genetic code kicks in and the change in that single nucleotide results in the same amino acid produced as the original code. 2) Missence Mutation = When the change in a single amino acid changes the amino acid produced 3) Nonsense Mutation = When the change in a single nucl...

GENETICS FINAL EXAMS| GENETICS TEST BANK|415 QUESTIONS WITH 100% CORRECT ANSWERS| LATEST UPDATE 2024|2025 - Crossover or DNA recombination occurs in eukaryotes between non-sister chromatids during prophase of meiosis Recombination also occurs between prokaryotes (via conjugation) and as a means of viral integration into a host cell The molecular mechanisms of crossover differ by species, but always in- volves the exchange of DNA between adjacent chromosomes These mechanisms are still the...

BIOLOGY AQA AS 74011 PAPER 1 [WELL VERIFIED] • The human cell then makes a complementary strand to the HIV DNA. The complementary strand is made in the same way as a new complementary strand is made during semi-conservative replication of human DNA. Describe how the complementary strand of HIV DNA is made. - ANS---- there are complementary nucleotides/bases pair - DNA polymerase used - Nucleotides join together (to form new strand)/phosphodiester bonds form; Contrast the structures of ...

CBE 555"Which of the following statements are correct? Explain your answers. A. A DNA strand has a polarity because its two ends contain different bases. B. G-C base pairs are more stable than A-T base pairs." - correct answer "A. False. The polarity of a DNA strand usually refers to the orientation of its sugar-phosphate backbone: one end contains a phosphate group, the other end contains a hydroxyl group. B. True. G-C: 3 H-bonds vs A-T: only 2 H-bonds " "Histone proteins are among t...

In a prokaryote, translation of an mRNA can start before transcription ends. This is not possible in eukaryotes. Why? a. nuclear ribosomes allow prokaryotes to do this work faster b. eukaryotes transcribe mRNA in the cytoplasm first, and then it is sent to the nucleus for transcription c. eukaryotes transcribe mRNA in the nucleus first, and then it is sent to the ER/cytoplasm for translation - ANSWER ☑☑c. eukaryotes transcribe mRNA in the nucleus first, and then it is sent to the ER/cy...
