DNA Replication

Question 1

what is DNA synthesis

Answer 1

DNA synthesis is when one strand of DNA “unzips” down the middle through the hydrogen bonds to create 2 half stands of DNA

Question 2

Describe the process of DNA synthesis

Answer 2

• The enzyme, helicase will unzip the DNA by splitting the double helix’s.
• Nucleotides in the cytosol will move together to join at the corresponding nitrogenous base pairs at the half stand of DNA
• These nucleotides in the cytosol are made from the food we eat.

Question 3

what is DNA

Answer 3

deoxyribonucleic acid

Question 4

what is RNA

Answer 4

ribonucleic acid

Question 5

what are the two main differences between DNA and RNA

Answer 5

1. DNA is a double helix while RNA is a single strand
2. In RNA there is no thymine, it has been replaced by a slightly different nitrogenous base called uracil.
