1Which enzyme is primarily responsible for the transcription of mRNA from a DNA template in eukaryotic cells?
2
During DNA replication, which protein helps relieve the physical tension and twisting generated by the unzipping of the DNA double helix?
3If a specific cell produces a mature mRNA that is much shorter than the original DNA gene sequence, which process likely explains the difference in length?
4In the mitochondrial electron transport chain, what is the final electron acceptor that results in the production of water?
5When human cells operate under anaerobic conditions and cannot perform oxidative phosphorylation, which product is generated during fermentation to allow glycolysis to continue?
6In photosynthesis, what molecule provides the replacement electrons for Photosystem II after it has been excited by light?
7Which type of mutation is most likely to result in a significantly shorter, non-functional protein by introducing a premature stop codon?
8If an organism has a diploid number (2n) of 48, how many chromosomes would typically be found in one of its gametes (sperm or egg)?
9A female carrier of an X-linked recessive disease (XHXh) marries an unaffected male (XHY). What is the probability that a son born to them will be affected by the disease?
10Where are the primary locations in a plant cell where ATP is produced for general cellular work (excluding the sugars built in the Calvin cycle)?
