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 ...

Biology 1001 Final Exam Adam Hrincevich Questions and Answers Already Passed 1. **DNA's Hereditary Capacity**: Watson and Crick realized that DNA could encode a vast amount of hereditary information through its sequence of bases. 2. **DNA Strand Attachment**: The two polynucleotide chains in a DNA molecule are held together by hydrogen bonds formed between complementary bases. 3. **Inversions in Chromosomes**: Movements of DNA segments from one chromosome to another are not term...

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...

chapter 1 1. Viruses are a. infectious agents that infect exclusively multicellular organisms. b. noncellular particles that take over the metabolism of a cell to generate more virus particles. c. pathogens that replicate in complex growth media. d. cellular particles that belong to the archaea domain. e. microbes that consist of lipid membrane–enclosed genomes. 2. The analysis of DNA sequences reveals a. the ancient convergence of prokaryotes and eukaryotes. b. that prokaryotes and ...

Bis 2C, Pre-Lab #2 Bacteria and Archaea are often collectively referred to as prokaryotes because they lack a nucleus (pro=before, karyon=nucleus). But, as you can see from figure 2.1, they are not each other’s closest relatives. Because bacteria and archaea are so diverse, they can be difficult to characterize. However, when compared to eukaryotes, they have significant differences in their general biology including, reproduction, organization of genetic material, and a lack of membrane...

Eukaryotic Chromosomes - ️️The multiple linear chromosomes in a eukaryotic nucleus are highly condensed Degree of coiling and packing changes throughout cell cycle Interphase: relatively more relaxed = less condensed Mitotic phase: relatively more compact = fully condensed for movement of individual chromosomes during cell division Genome size - ️️The genomes of different species contain different amounts of DNA. The complexity of an organism doesn't necessarily match the amou...
