DNA and Genes
Describe the shape of DNA.
The double helix is shaped like a twisted ladder. Sugars and phosphates form the sides, and the rungs are made of base pairs.
In RNA, what base bonds with adenine?
Uracil
In which phase of the cell cycle do cells spend most of their existence?
Interphase

Where does Transcription take place?
Nucleus
In which phase of mitosis do the sister chromatids separate into two different chromosomes?
Anaphase

Only two possible base pairings exist within a DNA molecule. What are they?
Adenine always pairs with Thymine, and Cytosine always pairs with Guanine.
During transcription, the information in a DNA molecule is copied to produce ________ molecule.
a. mRNA
b. tRNA
c. rRNA
d. another DNA
mRNA
What is the purpose of meiosis?
Produce egg or sperm cells that have only one copy of each chromosome.

False
A group of three nucleotides that codes for an amino acid is called a(n) ________.

How do asexual reproduction and sexual reproduction differ?
Asexual Reproduction: Results in only using mitosis and produces identical offspring
Sexual Reproduction: Involves two organism, each giving a copy of their genes to form a new organism and results in offspring that are different.
