DNA and Cell Genetics

The shape of DNA can be described as:

• Antiparallel, double helix

• Parallel, double helix

• Piral, single helix

The backbone of DNA is called the ___-___ backbone.

The name of the combined nitrogenous base, phosphate group, and deoxyribose sugar:

• Nucleic acid

• Nucleotide

• Nitrogen

• Nucleus

The complementary bases are held together by which bonds?

The nitrogenous bases for DNA are:

• Adenine, Thymine, Guanine, Cytosine

• Arguan, Thyroid, Guana, Cyroid

• Adenine, Thymine, Guanine, Uracil

• Adanin, Thymane, Ginani, Cytosane

The first step of DNA replication is:

• Two identical molecules of DNA are made

• Two strands of DNA are separated

• Complementary Nucleotides are matched up with the nucleotides on each strand

• DNA is thrown out through the vacuole

DNA ___ unwinds the DNA.

What is the replication fork?

• A cell that duplicates RNA

• The space outside of the DNA

• The junction between the unwound part and open part

1. The DNA being copied is called the ___ strand.

What puts in the complementary nucleotides?

• DNA Polymerase

• RNA Polymerase

• Polymerasa
