- What are the requirements for strand elongation by DNA polymerase enzymes?Describe three major differences between leading and lagging strand synthesis. What feature of DNA polymerase results in the leading and lagging strands being synthesized differentlyWhat is the difference between DNA polymerase and RNA polymerase?
- In terms of new DNA strands that are generated, what are the differences between replication and conventional polymerase chain reactions?What is the function of DNA helicase and what is the function of the DNA polymerase?What is the difference between the leading strand and the lagging strand in DNA replication? There are different DNA polymerases involved in elongation of the leading strand and the lagging strand. The leading strand is synthesized continuously in the 5' → 3' direction, while the lagging strand is synthesized discontinuously in the 5' → 3' direction. The leading strand requires an RNA primer, whereas the lagging strand does not. The leading strand is synthesized in the 3' → 5' direction in a discontinuous fashion, while the lagging strand is synthesized in the 5' → 3' direction in a continuous fashion.
- In one, simple sentence define the function of the following 1. Helicase = 2. Alpha subunit of DNA polymerase III =In terms of the new DNA strands that are generated, what are the differences between replication and conventional polymerase chain reaction?Assume a deletion occurs in a gene that encodes DNA polymerase I and no functional DNA polymerase I is produced. What will be the most likely consequence of this mutation? The DNA would not exist in a supercoiled state. There would be no RNA primers laid down. The DNA will not be able to unwind to initiate replication. The DNA strands would contain pieces of RNA. There would be no DNA replication on the leading or lagging strands.
