Biochem Help: Cell Cycle Protein Synthesis Q&A

Click For Summary
SUMMARY

The discussion centers on the synthesis of proteins during the cell cycle, specifically identifying which proteins are predominantly synthesized in the S phase. The correct answer to the posed question is Histones, as they play a crucial role in DNA stability and are essential during DNA replication. Other options like Cyclins, DNases, RNA polymerases, snRNPs, and Tubulins do not primarily relate to the S phase events. The participant references a PubMed article for further clarification on this topic.

PREREQUISITES
  • Understanding of the cell cycle phases, particularly S phase
  • Knowledge of protein synthesis mechanisms
  • Familiarity with histone function in DNA stability
  • Basic concepts of molecular biology and biochemistry
NEXT STEPS
  • Research the role of Histones in DNA replication
  • Study the function of Cyclins in cell cycle regulation
  • Explore the mechanisms of RNA polymerases during transcription
  • Investigate the significance of snRNPs in RNA processing
USEFUL FOR

Students and professionals in biochemistry, molecular biology, and genetics, particularly those studying the cell cycle and protein synthesis mechanisms.

Biochem help :(??

Hi :smile:
I have seen great people on this forum, can anybody please help me with this question?

Q- The majority of cellular proteins and RNA are synthesized throughout the cell cycle and are only interrupted briefly during M phase. Synthesis of which of the following proteins occurs predominantly in S phase of the cell cycle?

A) Cyclins

B) DNases

C) Histones

D) RNA polymerases

E) snRNPs (small nuclear ribonucleoproteins)

F) Tubulins

thanks in advance :shy:

Do you know what is the major evenet during the S-phase? This should eliminated four of the choice that do not have any related role with to this event. One choice has a direct role in contolling the S-phase events whereas the last remaining protein is an absolute require for DNA stability.

this paper gives the answer

Thanks Ian

I read about it. Histones is the answer. Sorry I am studying Biochemistry at med school, but was trying to solve questions before doing a good review. Sorry.
Thanks again.
