What happens in Interphase? SELECT ALL that apply.
Growth
DNA Replication
Usual Functions
Chromosomes are separated apart
chromosomes line up in the middle
What is the job of mRNA?
Carry genetic information from the nucleus to the ribosomes found in the cytoplasm
Makes up the ribosomes
Carries Amino Acids and transports them to the ribosome
Blueprint of life
What is the job of tRNA?
Carry genetic information from the nucleus to the ribosomes found in the cytoplasm

Carries Amino Acids - transports them to the ribosome to create a protein
Blueprint of life
What is the job of rRNA?
Carry genetic information from the nucleus to the ribosomes found in the cytoplasm
Helps Make up the ribosomes
Carries Amino Acids - transports them to the ribosome to create a protein
Blueprint of life
What is cancer?
Mitosis - Normal Cell Cycle
Uncontrolled Cell Growth
A virus
When cells divide through meiosis
What is a tumor?
accumulation of cells that grow uncontrollably
disappearance of cells
a ball of grease
something that is permanent in your body
What part of the cell cycle is where DNA the most vulnerable?
G1
G2
Mitosis
Synthesis
Chargaff's rule states:
there is equality in the amount of bases paired A=T and G=C
adenine pairs with guanine
thymine pairs with uracil
the amount of adenine will never match thymine
If in a segment of DNA there is 40 Thymine bases how many Adenines should we find?
60
100
40
70
A segment of DNA has 85% Guanine what percent of that same segment will be Cytosine?
85%
58%
15%
10%
What part of a DNA molecule codes for an organisms characteristics?
the hydrogen bonds
the covalent bonds
nitrogenous bases
deoxyribose sugar
phosphates
During Interphase -Synthesis DNA is Replicated: Match the following DNA segment with its complimentary strand.
ATCGTTAAGGCC
TAGCAATTCCGG
UAGCAAUUCCGG
ATCGTTAAGGCC
GGCCTTAACGAT
During Protein Synthesis: A DNA segment is used to create an mRNA strand. Match the following DNA segment with its mRNA strand.
ATC GTT AAG GCC
TAG CAA TTC CGG
UAG CAA UUC CGG
ATC GTT AAG GCC
GGC CTT AAC GAT
Whenever there is a change in a DNA sequences this indicates that:
there is a mutation
there is a wrong piece of DNA there
the cell is replicating
the cell is undergoing interphase
When a SINGLE nucleotide is REPLACED in a DNA sequence for another nucleotide that does not belong there we call this mutation:
EX: ATT GGA CCC => ATT GTA CCC
Deletion
substitution
Nondisjunction
Insertion
When a nucleotide is erased in a DNA sequence we call this mutation:
EXAMPLE: ATT GGA CCC => ATG GAC CC
Deletion
substitution
Nondisjunction
Insertion
When a nucleotide that does not belong is added to a DNA sequence we call this mutation:
EXAMPLE: ATT GGA CCC => ATA TGG ACC C
Deletion
substitution
Nondisjunction
Insertion
Crossing over in Chromosomes during Meiosis causes gametes formed to:
have genetic mutations
damage the DNA
increase the genetic diversity of the 4 cells produced
Go through the entire meiosis cell cycle again
Sharing a common ancestor means:
genetic code is similar and we are related
we are 100% the same as our ancestors
we are not related
we look similar
Click ALL that Apply: Proteins:
speed up chemical reactions
slow down chemical reactions
help build muscle
are the Blueprint of life
provide support for our body
True or False: Enzymes function at their best if they are in their optimal environment. Each enzyme has a specific function and therefore a specific range of temperature and acidity it performs best in.
True
False
Enzymes help reactions speed up by:
lowering activation energy
making the activation energy higher
changing the temperature
changing the acidity
True or False: Different Enzymes perform different functions in our body?
True
False
Amylase:
breaks down carbs starches into sugar
breaks down fat
breaks down proteins
unwinds the DNA molecule during DNA repication
Helicase
breaks down carbs starches into sugar
breaks down fat
breaks down proteins
unwinds the DNA molecule during DNA repication
Lipase:
breaks down carbs starches into sugar
works with liver bile and break down fats
breaks down proteins
unwinds the DNA molecule during DNA repication
Protease:
breaks down carbs starches into sugar
works with liver bile and break down fats
breaks down proteins into amino acids
unwinds the DNA molecule during DNA repication
What even is Crossing Over during MEIOSIS ?? >.<
Crossing over is the copying of genetic material that occurs in the germ line causes clones
Crossing over is the mutation of genetic material that occurs in the germ line causes tumors.
Crossing over is the swapping of genetic material that occurs in the germ line creates variation.
Crossing over is not even a thing.

Dominance means:
indifference
power and influence over others, take over
weakness
compromise
Codominance means:
One trait takes over completely masking the other inherited allele
Instead of being dominant on one trait over the other, BOTH traits occur.
Incomplete Dominance means:
One trait takes over completely masking the other inherited allele
Instead of being dominant on one trait over the other, BOTH traits occur.
Instead of being dominant or both traits occurring, there is a fusion between alleles.
