Question

In relation to central dogma of molecular biology answer the following questions:

A- Give two reasons why the DNA replication is asymmetrical process (i.e. the DNA replication outcome is different between the leading and lagging strands)? 

 

 

B-The following segment of DNA is part of the transcription unit of a gene. You know already that RNA polymerase moves in a specific direction along this piece of DNA to convert one of the DNA strands into a single strand RNA transcript so that this entire region of DNA is made into RNA. 

5′-GGCATGGCAATATTGTAGTA-3′

3′-CCGTACCGTTATAACATCAT-5′

 

Given this information, a student claims that the RNA produced from this DNA is:

3′-GGCATGGCAATATTGTAGTA-5′

Give two reasons why this answer is incorrect.

 

 

C- Imagine that the mRNA codons consisted of only two nucleotides instead of three nucleotides. Would there be a sufficient number of codons for all twenty amino acids? Explain your answer. 

 

 

 

D- The length of a particular gene in human DNA, measured from the start site for transcription to the end of the protein-coding region, is 10,000 nucleotides, whereas the length of the mRNA produced from this gene is 4000 nucleotides. What is the most likely reason for this difference?
