- The anticodon on the mRNA recognizes the codon on the tRNA.
- The consensus sequences in a prokaryotic promoter are 5'TTGACA3' and 5'TATAAT3' at -35 and -10, respectively. What sequence would be most easily recognized by σ factor?
- In yeast, which of the following is similar to the oriC region of prokaryotes?
- The fact that the two DNA strands are arranged in opposite orientations gives DNA its _____ characteristics.
- The wobble base is the second base of a codon.
- Which of the following is found at the end of a eukaryotic chromosome?
- DNA polymerase III has the ability to begin synthesis of the new daughter strands immediately following the formation of the replication fork.
- Kozak's rules for translation are similar to those for transcription in prokaryotes in that they both contain consensus sequences. In prokaryotes, the promoter consensus sequences are at −35 and −10. Where is the consensus sequence for translational initiation according to Kozak's rules?
- Which of the following would be considered an activated amino acid?
- A ribozyme is a catalytic protein that assists in the processing of tRNA.
- What enables the splicing of group I and II introns?
- Human chromosome 3 is almost 200 million base pairs in length. How many origins of replication do you predict will be found on human chromosome 3?
- A double stranded stretch of eukaryotic DNA is 250,000 bp long. If the average linker is about 54 base pairs, how many nucleosomes would be present on this piece of DNA?
- If eukaryotic cells evolved such that lagging strand DNA synthesis could occur continuously (without the use of Okazaki fragments), what enzyme would likely no longer be needed for DNA replication?
- Which enzyme fills in small regions of DNA where the RNA primers were located?
- Based on their known functions, which of the enzymes in the following pairs play a similar role in prokaryotes and eukaryotes?
- Choose the RNA molecule that would be complementary to this DNA molecule: 5'-TTAACCGG-3'.
- The problem of replicating the 3′ ends of chromosomes is solved by using the enzyme telomerase.
