Protein synthesis:
1. Develop a representation of how traits in organisms are the result of DNA structure. Be sure to include:
A. Describe Transcription: process? purpose? What is the relationship between RNA sequence and DNA
sequence?
B. Describe Translation – be sure to define AND include the role/names of the 3 types of RNA. What is the
relationship between protein structure and the sequence of bases in RNA?
2. Where is mRNA made in the cell? _____________________________________
3. Where are proteins made in the cell? ____________________________________
4. What are the building blocks of proteins? ________________________________
5. What is the relationship between DNA, traits and proteins?
6. What is the purpose of the protein collagen? ______________________________
7. Enzymes are what type of macromolecule? _____________________________
Asexual reproduction:
1. What cellular process does the picture show?
2. What is the purpose of the cellular process in the picture?
3. If a bacteria cell had 4 chromosomes and went through binary fission, how many chromosomes will the
identical offspring have?

Sexual reproduction:
1. What is the purpose of meiosis? Are the new cells identical to the parent cell?
2. How many chromosomes are in cells at the end of mitosis vs. end of meiosis?
3.
If a sperm cell has 6 chromosomes how many chromosomes will a fertilized zygote have?
4. True or False: Sexual reproduction increase genetic variation.
5. Explain your answer to the true/false question above. (Describe how and why)
6. The picture below shows a chromosome. What do each of the bands
on the chromosome represent? ____________________________
7. What is each “band” used to code for?
8. Describe cancer:
 What is the definition of cancer?

Do cancer cells divide in less or more time? Explain why.
9. Draw a label the male plant part that preforms meiosis.

Punnett squares (SHOW YOUR WORK)
1. Hemophilia is a X-linked recessive trait. A female who is a carrier has children with a male who does not
have hemophilia. Complete the punnett square for the couple’s offspring. What percentage of the female
offspring will have hemophilia? What percentage of the male offspring will have hemophilia?
2. The length of a dog’s tail is an inherited trait. The allele for short tails is dominant (T) over the allele for
long tails (t). A dog breeder mates two short-tailed dogs (parents). One parent is homozygous and the other
is heterozygous for this trait. A litter of twelve puppies, all with short tails, is produced (first generation).
The breeder mates one of the first generation dogs with a short-tailed dog from another litter. A litter of ten
puppies is produced (second generation). The breeder is surprised when one of the second generation
puppies has a long tail. Describe the genetic make-up of the parents and puppies that produced this
inheritance pattern.
Pedigrees:
1. What are the possible genotypes of person 1? What is the phenotype?
2. What are the possible genotypes of person 2? What is the phenotype?
3. In the pedigree chart above, is the inherited trait sex-linked? ___________ How can you tell?
