In Gel Electrophoresis, how does the length of DNA strand determine how long it will travel along the gel?
Shorter fragments will travel further than longer fragments
Name the four DNA Nitrogenous bases (actual names)
and what pairs with what
What is Thymine bonds to Adenine. Cytosine bonds to Guanine.
What enzyme adds new nucleotides to the separated strands?

Explain Somatic Cell Nuclear Transfer
In SCNT, the egg cell's single set of chromosomes is removed. It is replaced by the nucleus from a somatic cell.
Why is ribose or deoxyribose called a pentose sugar?
Because it has 5 sides
DNA Replication is said to be semi-conservative because
What is each copy has an old strand and a new strand
in a DNA sequence, 19% of nucleotides have Adenine bases.
What % have Guanine bases?
What is 31% Guanine
What does PCR stand for? What does it do?
Polymerase chain reaction. A lab method that amplifies a sample of DNA (makes many copies).
