Worked Solution & Example Answer:The graph below shows the relative amount of mRNA for the production of histone protein at different times throughout a cell cycle - VCE - SSCE Biology - Question 21 - 2015 - Paper 1
Step 1
C. histone protein synthesis occurs simultaneously with DNA synthesis.
Answer
Histone proteins are crucial for DNA packaging and organization. During the S phase of the cell cycle, DNA is replicated, and it is essential for histone proteins to be synthesized to facilitate this process. The graph indicates that there is a peak in mRNA levels for histone proteins during the S phase, which aligns with the timing of DNA replication. Thus, option C is correct.
