Question

dna replication
directions:

1. using the base pairing rule, fill in the missing base pairs in the parent dna molecule
2. copy the base pairs the following colors: a = green; c = purple; g = red; t = yellow
3. color the p-d-p-d backbones of the parent molecule light blue
4. the parent molecule will now split down the middle. follow the left half of the parent molecule along the arrow and copy it exactly (colors and all) into the daughter dna molecule. do the same for the right half of the parent molecule
5. fill in the base pairs for the new half of each daughter dna molecule
6. color the new bases using the color key above. then color the new p-d-p-d backbone orange
7. fill in the identification key

p = phosphate group

summary of dna replication
parent dna molecule splits down the center and separates
daughter dna molecules
new nucleotides move in and base pair with each side of the parent molecule
questions:

1. are the two daughter strands identical to the parent dna molecule?
2. how much of the parent dna molecule makes up one daughter dna molecule?
3. in the summary box above, summarize the process of dna replication in your own words. it may help to break it down into severa

Explanation:

1. DNA replication follows the semi - conservative model. Each daughter DNA molecule has one strand from the parent (conserved) and one newly synthesized strand. But due to base - pairing rules (A - T and G - C), the sequence of bases in the daughter strands is identical to the parent DNA molecule.
2. In semi - conservative replication, each daughter DNA molecule consists of one strand from the original (parent) DNA molecule. So, 50% (or one - half) of the parent DNA molecule is in each daughter molecule.

Answer:

1. Yes, the two daughter strands are identical to the parent DNA molecule.
2. 50% (or one - half) of the parent DNA molecule makes up one daughter DNA molecule.
