Natural Selection
100
Help determine the probability of offsprings genes and physical features
What are punnett squares?
100
a mutation that results in a change in the DNA strand
What is a Gene Mutation?
100
allows all cells to receive a copy of the organisms DNA in the nucleus.
What is DNA replication?
100
Adenine, Uracil, Cytosine, Guanine
What are the bases in RNA?
100
Organisms better adapted to their environment will survive and reproduce more successfully than those not better adapted.
What is Natural Selection?
200
BB, Bb, bb
What are Genotype examples?
200
a mutation that results in a change in number or parts of chromosomes
What is a chromosomal mutation?
200
Apples in the Tree, Car in the Garage
How do DNA bases pair?
200
True or False: RNA is double stranded
What is False?
200
overproduction, inherited variation, competition, successful reproduction
What are the steps to natural selection?
300
Brown eyes, red hair, freckles
What are phenotype examples?
300
this mutation may result in the same protein and no change to the organisms function
What is Substitution Gene Mutation?
300
A DNA strand has 30 cytosine bases and 15 thymine bases. How many glycine and adenine bases does it have?
What is 30 glycine and 15 adenine?
300
DNA strand: A T G G C T
mRNA: ???
mRNA strand: U A C C G A
300
True or False: Natural selection can lead to new species formed due to evolution
What is True
400
What are the genotypes of a cross between a homozygous red flower and a heterozygous red flower? R = red, r = white
50% homozygous dominant
50% heterozygous
400
these mutations cause a frameshift mutation and result in changes to the protein structure.
What are deletion and insertion gene mutations?
400
Replicate the DNA strand below:
Original Strand: A T G C A A A T
Complimentary Strand: T A C G T T T A
400
Original DNA strand: T T C G A A
Mutated DNA Strand: A A G U U
What mutation is represented above? AND will the protein change?
What is deletion? Yes the protein will differ.
400
How does natural selection lead to extinction?
Those who do not have beneficial traits will not survive and reproduce lowering the population.
500
Below is a dihybrid punnett square:
T = tall , t = short
G = green , g = yellow
Cross a Tall Green plant with a Short Yellow plant. (The first column and row is done for you)
How many will be Tall - Green, Tall - Yellow, Short - Green, Short - Yellow? There are 16 possibilities.
100% will be Tall Green plants

What is a picture of a translocation mutation?
500
What is the missing step to DNA replication below? (You must say what it does)
Helicase separates the two original DNA strands.
DNA polymerase adds complimentary bases to the original DNA strand
Ligase will seal together the lagging strand
What is primase putting a starting point for DNA polymerase.
500
Original DNA Strand: T G C C A T A A G
mRNA: A C G G U A U U C
Amino acid: Threonine - Valine - Phenylalanine
Mutated DNA Strand: T G G G A T A A G
mRNA strand: ?
Amino Acid: ?
Did the amino acid chain change?
ACC CUA UUC
Threonine-Leucine-Phenylalanine
No the protein is the same.
500
How does natural selection lead to evolution and changes in species populations?
Species with the most beneficial trait for the environment will be able to survive and reproduce passing down beneficials traits that can lead to evolution in populations.
