c. Logical thinking using Chargaff's rules - In a strand of DNA, if the percentage of adenine was 20%, the percentage of guanine in the same strand must be
d.
Why is DNA replication called semi-conservative?

What does it mean that the two strands of DNA are complementary?
I will have to grade this.
Reorder the following steps from beginning to end.
A complementary strand is created for each of the two strands of the original double helix.
The DNA double helix breaks or unzips down the middle between the base pairs.
The enzyme DNA polymerase moves along the exposed strands and adds complementary nucleotides to each nucleotide in each existing strand.
Two new identical DNA molecules have been produced.
Below is one-half of a DNA molecule. Create the complementary strand (USE UPPERCASE LETTERS).
