DNA and RNA
Compare and contrast
DNA and RNA. Discuss why humans did not evolve with one central
repository of DNA, but rather it is replicated throughout the
body?
Your assignment should
be 250-500 words in length.
IN YOUR OWN WORDS
PLEASE!!!! NO PLAGIARISM!!!!!!
6. Compare the
structure and function of a typical DNA polymerase and a typical
RNA polymerase.7. What are the
post-transcriptional modifications that the pre-mRNA is subjected
to in eukaryotes? Explain by giving the role(s) of each
modification.8. Highlight the
general characteristics of a mature mRNA in comparison with rRNA or
tRNA
compare and contrast one RNA virus (polio or influenza) and one DNA
virus ( herpes or sv-40) replication within a cell. and how each
presents mRNA to the cell and how more genomes are made for the
virus
Compare the proofreading mechanisms of DNA and RNA polymerase.
Specifically,
which active site is required for proofreading by each enzyme and
what are the products of
this activity?
Compare and contrast the accuracy of:
DNA replication
RNA synthesis
Protein synthesis
What mechanisms are used to ensure the fidelity of each of these
processes? in writing no diagrams or pictures
Transcription: From DNA to
RNA
1. Define a gene.
2. How does RNA differ from DNA?
3. Briefly describe the process of transcription.
4. Describe the process of transcription as it occurs in
prokaryotes.
5. What is the role of the promoter?
6. Describe the process of transcription as it occurs in
eukaryotes.
7. What is the role of the transcription factors? A mutation
exists in transcription factors that causes them to bind slightly
downstream of the TATA box, causing...
