DNA and RNA, biology assignment help

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.

———————————-

Describe the role of double helix in complimentary base pairing in DNA replication. What does it mean when we say that the two strands of DNA in the double helix are antiparallel? What would the end of the double helix look like if the strands were parallel? Remember to cite any references you use in proper APA format.

This should be 75 to 150 words, but may go longer depending on the topic.
