Answer #1

the region in the nucleoplasm where rna is used to produce the subunit of ribosomes is called
NUCLEOLUS.
It is the darkly stained region in the nucleus.
This is the region where ribosome biogenesis occurs.
rRNA genes are transcribed as a single unit by RNA polymerase I and several associated factors.

  • Attenuation works through the action of ribosomes binding to an mRNA and signaling to RNA polymerase...

    Attenuation works through the action of ribosomes binding to an mRNA and signaling to RNA polymerase whether it should terminate transcription or not. However, once that decision is made (one way or the other), it would seem wasteful for the leader peptide to continue to be made; after all, the decision has been made, and thus there is no more need for ribosomes to act. Invent a model that would allow the attenuation region to no longer be involved in...

    Part A The sigma (?) subunit binds to the core RNA polymerase enzyme. The function of this sigma factor is to recognize and bind to the promoter of a gene so that transcription can be initiated. The closeup shows the secondary structure of the sigma (?) subunit, which consists of four domains. Identify the domains labeled 1-3. The sigma (?) subunit binds to the core RNA polymerase enzyme. The function of this sigma factor is to recognize and bind to...

    Please help explain why they are false? thanks 1. Ribosomes are large RNA structures composed solely of rRNA. 2. Ribosomes are synthesized entirely in the cytoplasm. 3. A ribosome binds one tRNA at a time. 4. Ribosomes must bind to the 5′ cap before initiating translation 5. Misfolded proteins are delivered to the proteasome, where they are sequestered from the cytoplasm and can attempt to refold.

    1. The virus hijacks the cell, and RNA polymerases produce the complement to the positive stranded RNA genome. We can call these strands negative strands, and they then serve as templates for RNA polymerases to produce their complement. How does the sequence of these strands, the complement to the negative strands, compare with the original viral genome? 2-1. RNA polymerases lack proofreading ability. Define proofreading ability and describe its importance in replication of DNA genomes. a. Why is this a...
