Name Class Date RNA (pages 146-148) | SECTION REVIEW In this section you were introduced to the molecule that helps put the information in DNA to use: ribonucleic acid, or RNA. ANA Iis a nucleic acid that carries information from DNA to the ribosomes, the organelles in which proteins are made. RNA also carries out the process by which proteins are assem- bled from amino acids. RNA is quite similar to DNA in structure. However, there are some important differ- ences. RNA is single-stranded; DNA is dou- ble-stranded. RNA contains the sugar ribose; DNA contains deoxyribose. And RNA has the nitrogenous base uracil; DNA has thymine. In this section you also learned about the process of transcription. Transcription is t process in which part of a DNA molecule is used as a template for the synthesis of a com- plementary strand of RNA. This process is mediated by an enzyme called RNA poly- merase. The strand of…arrow_forwardIn a clinical context, a scientist is working with a viral DNA which is about 24000bps long. There are two known variants of the virus that share almost the same DNA but for a final fragment; with reference to Figure Q2b, the regions A and B are conserved in both variants, while the region C differs and is either 320bps (variant 1) or 380bps (variant 2).

- This is a three part question: Figure B in Box 4.1 illustrates the results of the Meselson-Stahl experiment after a single cycle of replication in 14N. (a) Explain the results they observed after two rounds of replication in 14N medium. (b) Draw out the expected results if a third round of replication were allowed in 14N medium. (c) Two other models for template-directed replication were considered as alternatives to semi-conservative replication. One of these was conservative replication, in which the parental strands were unpaired, replicated, then reannealed such that the parental strands stayed together and the newly synthesized strands were together. The second model was dispersive replication, in which one strand was used as the template for polymerization, then the polymerase switched to using the other strand as the template, and subsequently switched back and forth between the two strands until bother were fully replicated. Each of these models is ruled out by one of your…arrow_forwardDescribe the “end-replication problem” in eukaryotes.

(a) For example, one mutation in a viral gene changed a GAU codon to a GGU codon. How does this change affect the sequence of the polypeptide encoded by that gene? (b) In another variant form of the virus, a gene is missing six consecutive nucleotides. How would this change affect the sequence of the polypeptide encoded by that gene? (c) In another coronavirus variant, the spike protein (the prominent protein on the surface of the virus) contains a histidine residue where an aspartate (aspartic acid) residue should be. Describe a point mutation in the coronavirus genome that could have caused this change in the spike protein.arrow_forward
