DNA all day
In eukaryotic cells, where does DNA replication primarily occur?
nucleus
A gene is a sequence of DNA that contains the instructions to make one or more_____________.
Proteins
What is the product of mitosis?
two identical daughter cells
The process of cell division results in four daughter cells with half the genetic information of the parent cell.
Meiosis
________________ is the change in the frequency of alleles in a population over time.
Evolution
What enzyme is responsible for unwinding the DNA double helix during replication?
Helicase
What is the final product of gene expression?
Proteins
When does DNA replication occur in the cell cycle?
Interphase
If an animal's skin cell has 20 chromosomes how many chromosomes does its sperm cells have?
10
The process by which individuals with advantageous traits are more likely to survive and reproduce.
Natural selection
What is the function of DNA polymerase during DNA replication?
To add complementary nucleotides to the new DNA strand
Proteins are made up of chains of _____________________.
amino acids
List the three major steps of the cell cycle in the correct order.
1. Interphase
2. Mitosis
3. Cytokinesis
In a Punnett square, the letters on top of the square and on the side of the square represent_____________.
parental genotype
____________________ leads to the adaptation of populations to their environments over time.
Natural selection
A phosphate group bonded to a deoxyribose sugar and a base is a _____________.
Nucleotide
The transfer of genetic information from DNA to RNA is called 1.________________.
The process that uses mRNA to make proteins is 2.________________.
1. Transcription
2. Translation
What is the relationship between mitosis and cancer?
Cancer involves uncontrolled cell division.
The inheritance pattern that occurs when both alleles contribute to the phenotype of the heterozygote.
Codominance
Does the theory of evolution attempt to explain the origin of life on earth?
No!
Instead explains it the connectivity and diversity of the life we observe on earth today.
Why is DNA replication considered a semi-conservative process?
DNA replication does not result in a single brand new DNA double helix, but 2 DNA helixes each that have one new strand and on "conserved" original strand
Transcription occurs in the 1.__________ and translation occurs in the 2._____________ on a 3.____________.
1. nucleus
2. cytoplasm
3. ribosome
Which type of organisms on the tree of life are known to develop cancer?
Multicellular organisms like plants and animals
If a homozygous dominant plant (YY) is crossed with a homozygous recessive plant (yy), what will be the genotype of the all the offspring be?
Yy
Human birth weight being distributed evenly across a population is an example of what type of selection?
Stabilizing selection
