Biology Spring Final Review Guide

1)DNA Structure:What is a nucleotide? Draw a basic structure and label it’s three parts (phosphate, nitrogen base, sugar)

2)Base Pairing:Nucleotides always have a partner they match up with. Match the nucleotides in DNA and RNA.

DNA: A RNA: A

T U

G G

C C

3)DNA vs. RNA: Fill the following table out:

Nucleotides It Contains / Sugar Group it Contains / Number of Strands
Deoxyribonucleic Acid (DNA)
Ribonucleic Acid
(RNA)

4)Genetic Terms:What is the difference between DNA, genes, and chromosomes? (Draw a picture in each box to accompany your description of each)

5)Central Dogma:What is the story of the Central Dogma? Use the following words to fill in the blanks:

Locations: cytoplasm, nucleus, ribosome

Key Players: DNA, mRNA, tRNA, protein, amino acid/s

Processes:transcription, translation

The story of the Central Dogma begins with the ______which is found in the ______.

Then, the ______leaves the ______and goes to the ______where it finds a ______.

(Key Player 2) (Location 1) (Location 2) (Location 3)

In the ______, the message on the ______is read by the ______one codon at a time. Every

(Location 3) (Key Player 2) (Key Player 3)

three nucleotides on the ______is called a codon, and each codon represents an ______.

(Key Player 2) (Key Player 4)

As the ______reads the ______it brings the designated ______; this process is known as

(Key Player 3) (Key Player 2) (Key Player 4)

______. The ______link together to make a chain also known as a ______.

(Process 2) (Key Player 4) (Key Player 5)

The story of the Central Dogma in biology therefore explains how the instructions on the ______are

(Key Player 1)

used to make______, which is what most of our body is made of!

(Key Player 5)

6)Punnet Squares:Perform a cross between a heterozygous pea plant and a short pea plant. Tall is dominant. Use letters T and t as the alleles. Provide the probability of homozygous dominant, heter0zygous, and homozygous recessive offspring.
