Unit 10 DNA Replication

Question 1

Function of DNA Replication

Answer 1

• Crucial for CELL DIVISION and GROWTH –> copying and duplicating DNA molecule
• EXISTING STRAND is a template to build the NEW STRAND

Question 2

What are the functions of:
1. DNA Helicase
2. DNA Polymerase
3. Lagging Strand
4. DNA Ligase

Answer 2

1. UNWINDING the DNA
2. An enzyme that is responsible for CREATING and EXPANDING the NEW STRAND of DNA
3. Made of Okazaki Fragment
4. Enzyme that is important for TERMINATION (stop) DNA REPLICATION

Question 3

Difference between RNA and DNA

Answer 3

RNA:
1. One strand
2. Cytosine, Guanine, Adenine, Uracil
3. Ribonucleic acid

DNA:
1. 2 strands
2. Cytosine, Guanine, Adenine, Thymine
3. Deoxyribonucleic acid
