10. Would you expect all DNA, whether from a rose, a turtle, or a ballet dancer to be made from the same

phosphate groups, deoxyribose sugar, and the A,T, C, G nitrogen bases?

All living things are defined by DNA, the sequence of the code (number and order of nitrogen bases) might

be different, but all DNA is made up of an arrangement of the same 4 nitrogen bases.

11. How is DNA related to an allele?

Alleles are different version of a gene, like different versions that create dark hair and the other version

that creates light hair. Alleles are made up of DNA. The DNA is the code to create a specific version of a

trait.

the differences between

mitosis and meiosis.

mitosis and meiosis.

Replacement: Replace/repair old/dead cells

Reproduction: Create NEW organism

15. Why does DNA need to duplicate itself?

In order to get more cells, a cell divides. DNA makes a copy of itself so each cell has all the DNA it

needs.

16. Describe the process a cell uses to duplicate DNA. NOT REQUIRED ON THE QUIZ

But if you are curious ... the DNA strand unwinds, then splits between the nitrogen bases. Spare

nucleotides in the nucleus match up with each half according to A-T and C-G. When all the nitrogen
