Unit 8 DNA Teacher-Led Review

Question: Describe the structure of DNA in detail. Be sure to include all parts of the DNA molecule.

Weak Answer: Double helix, adenine and guanine bond together.

Strong Answer: DNA is in the shape of a double helix. The monomer of a DNA molecule is a nucleotide that always consists of a ribose (sugar), phosphate group, and nitrogen base. The different nitrogen bases are Adenine, Thymine, Guanine, and Cytosine.

DNA replication is Mitosis on an even more microscopic level.

Both take place in the nucleus.

DNA replication and Mitosis produce two identical sister chromatids.

The sister chromatids make up a chromosome.
