WorksheetsUnit 3: Methods of Reproduction
Total questions: 20
Worksheet time: 12mins
Why is it necessary for DNA replication to take place?
The more genetic information a organism has, the more evolved it is.
The extra DNA strand would be used when the original strand is damaged.
When the cell reproduces, each new daughter cell will have a DNA strand.
DNA is a living organism and needs to reproduce to survive.
What is the complementary strand for CATTGC?
GTAACG
GUAACG
CATTGC
CGTTAC
During S Phase, each DNA strand will have ---
1 original strand and 1 complementary strand
2 original strands and 2 complementary strands
1 mutated strand and 1 original strand
2 unique strands and 2 different strands
An unknown organism's DNA strand consist of 40% Adenine. What would be the percentage of the other Nitrogen Bases?
40% Thymine, 10% Cytosine, 10% Guanine
40% Cytosine, 10% Thymine, 10% Guanine
40% Guanine, 10% Cytosine, 10% Thymine
20% Cytosine, 20% Guanine, 20% Thymine
Asexual reproduction is a form of reproduction that produces ---
Unique offspring
Mutated offspring
Identical offspring
Evolved offspring
Which phase of the cell cycle does the cell synthesize genetic information?
G1
S
G2
M (cell division)
Which phase of the cell cycle does the cell prepare to divide?
G1
S
G2
M (cell division)
What are the 3 parts of a nucleotide?
Phosphate, Sugar, Base
Sugar, Base, Nitrogen
DNA, RNA, Genetic Information
Nucleus, Nucleolus, Genetic Information
What type of reproduction produces a unique offspring?
sexual
asexual
binary fission
conjugation
What will trigger the cell to divide and reproduce?
When it needs to populate its environment
When it needs to mate and reproduce sexually
When it is unable to obtain enough energy
When S phase occurs and copies DNA
If two organisms have similar structures, they will also share ---
a common ancestor
similar functions
the same environment
similar diets
What is the term for similar structures, but they have different functions?
homologous structures
analogous structures
vestigial structures
What is the term for different structures, but they perform similar functions
homologous structures
analogous structures
vestigial structures
If you were looking at embryos of different organisms, but they all look similar. You can conclude that ---
they have a common ancestor
they have the same exact DNA
they all live in the same environment
it is just pure coincidence
Which species is more closely related to Amphibians?
Sharks
Crocodiles
Birds
Rabbits
Which species has an amniotic egg? Select ALL that apply
Primates
Birds
Sharks
Amphibians
Before a cell can divide and reproduce, what must a cell do first?
Grow
Prepare to divide
Obtain energy
Copy genetic information
Which statement is invalid?
Cells have to divide to ensure they have enough energy to survive.
During synthesis phase, the genetic information is copied.
The last phase of the cell cycle produces 2 new daughter cells.
During G2 Phase, divide and produce identical daughter cells.
What would challenge the validity of this cladogram?
Hagfish that possess jaws to eat
Birds have feathers instead of fur
Salamanders breathe oxygen using their lungs
Chimps, being the most advanced have the most traits
According to the diagram, which statement is valid?
The diagram is incorrect because the base pairs do not match
The diagram is incorrect because there is not enough bases
The diagram is correct because the base pairs match
The diagram is correct because the sequence of nucleotides is in the correct order
