DNA is a stranded molecule. It is connected at the nitrogen bases by bonds. The nitrogen bases are to each other.
How does DNA serve as a genetic code? What does it code for?
Which part of the DNA specifically codes for traits? (The unique portion that can be different: A, T, C, G)
DNA provides instructions for the physical characteristics of living things. This may include blood type, eye color, bone structure, skin color, etc. How does the DNA within cells determine an organism's traits?
DNA is a acid that includes a series of monomers called that makes up a genetic for making proteins . The DNA is found in the of the eukaryotic cells and the cytoplasm of prokaryotic cells. DNA's genetic code is decoded into messages that are used to produce during a process called protein synthesis. DNA is a double- molecule with sides joined by complementary nitrogen pairs: adenine pairs with and cytosine bonds with .

These two cells are fused using an electric shock.
The fused cell begins dividing normally.
A donor cell is taken from a sheep’s udder.
The embryo is placed in the uterus of the foster mother.
The nucleus of the egg cell is removed.
The embryo develops normally into a lamb- Dolly.
An egg cell is taken from an adult female sheep
The DNA gel has many little pores that the DNA can move, or migrate, through. When the power is turned on, the DNA moves through these holes. This is why the fragments take longer to move across the gel while the fragments move very quickly.
Before placing the DNA fragments into the wells at the top of the gel, the DNA must be cut up into pieces. What biotechnology is used to cut the DNA at specific sites? (Think DNA scissors)
