Question

Special transcription factors can:

A) Interact with ribosomes
B) Influence flower development
C) Degrade RNA
D) Modify translation rate through interaction with RISC
E) Bind tightly to histone

Answer 1

Transcription factors are proteins that regulate gene expression by altering RNA polymerase activity and can influence biological processes like flower development, but they do not typically interact with ribosomes or directly modify translation processes.

Step-by-step explanation:

Special transcription factors have the capability to modulate gene expression by binding to DNA sequences and influencing the activity of RNA polymerase. These factors can regulate biological processes such as flower development or contribute to epigenetic changes by interacting with molecules that modify the structure of chromatin, such as proteins involved in histone acetylation. However, transcription factors do not generally interact directly with ribosomes or participate in translation processes, such as those involving the RNA-induced silencing complex (RISC) or translation initiation factors like eukaryotic initiation factor-2 (elF-2). Due to increased phosphorylation levels of eIF-2 in neurodegenerative diseases, protein synthesis can be impacted, potentially leading to a block in the translation of certain proteins.
