What is a diploid cell
What is a cell that has two copies of each chromosome
200
What is a chromosome made up of
What is DNA
200
Which nitrogen bases always bond together
What is a-t and c-g
200
why does DNA replication occur
What is because the new cells each need 46 chromosomes
200
how many cells does mitosis start and end with
What is one and two

these are pieces of chromosomes that are the instructinos for making protiens
What is genes
500
Name the four nitrogen bases
What is adenine thymine cytosine guanine
500
why is DNA replication semi conservative
What is because each new strand created has one old strand and one new strand
500
If a human cell is created thorough meiosis how many chromosomes will it have
What is 23
500
explain how meiosis lets you pass your traits to your children
What is the chromosomes from your cells which hold your traits are passed to your sperm and egg cells and this makes your children
