1. The use of RNA primer in DNA replication increases the
fidelity of DNA replication. Explain this statement.
2. Some errors in DNA replication can escape repair and this
is to some extent is beneficial for the evolution. Explain
why?
Most RNA viruses are single stranded and replicate in the
cytoplasm while most DNA viruses are double stranded and replicate
in the nucleus. Briefly explain why this makes sense for each of
these 4 characteritics (4 points). Each of the following viruses
breaks one of these (e.g. might be double stranded RNA virus). For
each of these viruses say which of these it breaks (4points). Bonus
points. Describe the major pathology for Molluscipox virus and B19
Parvovirus (2points). Rotavirus, Molluscipox...
Is RNA directly used in DNA replication?
1.RNA is not involved during the process of genome
replication
2.RNA is needed to provide the 3' -OH groups at the start of
construction of new DNA
3.tRNA is matched to the codons on the genome during DNA
replication
4.All of the monomers used to construct the new DNA molecule are
first constructed as RNA and then a -CH3 group is added
9.) During the process of DNA replication, both DNA polymerase
and RNA polymerase are involved in eventually creating the new
daughter strand of DNA. T or F
10.) Replication begins at the origin of replication or ORI and
transcription begins at the first codon for methionine. T or F
11.) The process of mapping, sequencing and analysis of proteins
is called genomics. T or F
12.) The heavy chain constant domains of a given immunoglobulin
molecule define its class. T...
