4/23/18 Student Names 1) Define the word replication 2) Write the composition of nucleotide 3) Explain the term 'bacteriophage" 4) Why was bacteriophage used in early experiments on DNA 5) Describe the structure of DNA 5) In a particular species, cytosine makes 25 %, how much will be the Guanosine 6) If cytosine content in DNA is 40%, How much will be thymine and adenine? 7) Explain semiconservative replication of DNA 8) Explain the term 'origin of replication 9) How does origin of replication differ in prokaryotes versus eukaryotes? 10) Explain replication fork

Explanation / Answer

1. The formation of identical copies of DNA is called replication.

2. Nucleotide contain

A sugar

A nitrogenous base

A phosphate group.

3. Bacteriophage is a virus that infects a bacteria and replicate inside it.

4. They were used in genetic engineering to replicate a particular segment of DNA .

5. If cytosine is 25% then guanosine will also be 25 % as they are complememtary bases.

6. If cytosine is 40% then guanosine will aslo be 40 percent and hence adenine and thimine will be 20 percent in total and as they are equal in amount so they will be 10 percent each.
