Name the four nitrogenous bases of DNA.
Adenine (A), Thymine (T), Guanine (G), & Cytosine (C)
5.
What does the double helix do in the first stage of replication of DNA?
It unwinds
6.
What is the role of Messenger RNA (mRNA)
the
It helps complete the building of the protein
Physically sequences the amino acids that are carried to the building site by
tRNA and chemically connected by the rRNA
7.
If replication of DNA were to be compared to the building of a house, what
would the DNA be compared to?
It would be the original blueprint that is kept in the main office (nucleus)
that directed the plan.
8.
Since segregation is random, predictable ratios of traits are found in the
offspring.
9.
Where are chromosomes located?
In the nucleus
10.

Deoxyribose sugar, phosphate & four nitrogenous bases
12.
Define diploid.
Number of chromosomes found in the somatic, or body cells
13.
Define haploid
Number of chromosomes found in the non-sex cells, or gametes.
14.
What is the role of RNA in general
A group of molecules in charge of reading and translating the genetic code
for the formation of new proteins.
