1- The two strands of the DNA double helix are held together by bonds between base pairs. I 2- DNA replication, each strand of DNA serves as a for a newly synthesized strand of DNA.
3- In gene expression, DNA is used as a template to make , which is then used as a template to make a polypeptide.
4- In the process of , DNA can be rearranged, which contributes to the genetic diversity of the species.
5- What are the differences between the structures of DNA and RNA?
6- How can the central dogma help us understand the process by which DNA is turned into protein? What are the two steps involved in the process of gene expression?
7- Why are replication and recombination two important roles of DNA?
