Question

1. What kind of pattern do you notice with the structure of DNA? For example, what pattern do you see with the rails and rungs of the ladder structure?
2.Briefly describe the DNA transcription process, which involves the transfer of the DNA genetic code onto an mRNA molecule.

Answer 1

The most obvious patter is that A binds with T and C with G, as is the case with DNA. 

The beginning of DNA transcription starts with the binding of the enzyme RNA polymerase to the promoter region. Next, RNA moves begins transcribing in the 5' to 3' direction using one strand of DNA as the template strand. This strand of RNA produced is complimentary with the other strand known as the coding strand except that Thymine is replaced by Uracil. To cleave the strand Bacteria can use what is known as Rho-independent termination where the strand makes a hairpin loop that causes stress and breakage. Or Rho-dependent termination where a protein causes an interaction between the template and mRNA and they disassociate. Termination is not really understood in eukaryotic organisms.
