Total questions: 10
Worksheet time: 3hrs 30mins
Students are modeling mRNA during the process of protein synthesis. Which answer choice correctly describes the model of the mRNA strand being transcribed?
The mRNA strand is complementary to the DNA template strand; however, uracil instead of adenine is paired with thymine.
The mRNA strand is complementary to the DNA template strand; however, uracil instead of thymine is paired with adenine.
The mRNA strand is an exact copy of the DNA template strand; however, uracil instead of adenine is paired with thymine.

A model of transcription and a codon chart are shown. Which amino acid would be coded first from the DNA strand being transcribed?
Cys
Phe
Ile
Met
A model of the genetic control of coat color in rabbits is shown. Which Punnett square represents a cross that would produce albino offspring?
A genetic cross involving two unlinked genes is represented.
AaGG x aaGg
Which genotype is NOT possible in the offspring produced by the cross?
AaGG
Aagg
aaGg
aaGG
Mice have two unlinked allele pairs that affect fur color. The table shows how allele pairs affect fur color. The term “agouti” describes fur with pigmentation that changes in each hair from the shaft to the tip, giving the fur a banded appearance. Mice with the aa allele pair are albino, regardless of the second allele-pair combination. What is the probability of albinism in the offspring of a cross between two mice with AaBb alleles?
1/16
3/16
4/16
9/16
What belongs in the last box?
RR
Rr
rr
ff
