2. What is the major difference between DNA and RNA?
- All of the above
- Most cellular RNAs re single stranded
- RNA is made up of a ribonucleotide monomer
- RNA contains uridine NOT thymidine
3. How is the 3' to 5' strand get synthesised?
- The lagging strand is copied as short fragments which are joined using DNA ligase
- The lagging strand is copied as RNA using a DNA primase
- The leading strand is copied continuously using RNA polymerase
- The leading strand is copied as short fragments started by RNA primers
4. How does the ribosome help form peptide bonds between amino acids?
- C. by catalyzing the reaction using the 28S rRNA as a ribozyme
- A. changes conformation to facilitate bond using the hydrolysis of GTP
- A and C
- B. by asking nicely for the AAs to hold hands
5. Peptide bonds do NOT exhibit which quality?
- The chemical properties are determined by the nature of the side chain (polar, acidic etc)
- Peptide bonds are panar but rotation exists around the alpha carbon
- Are very weak and easily broken with low energy reactions
- Are formed between the NH3 and COO- groups of 2 amino acids
