DNA Structure
What is the structure of DNA?
double Helix
What can you use Punnett Square for?
You can use it as a tool used to predict genetic outcomes.
What are Mutations?
They can occur naturally or be included by environmental factors.
What is Meiosis?
A type of cell division that produces gametes.
How does CRISPR Work?
It Utilizes a guide RNA to locate specific DNA sequences.
What are the four nucleotide bases?
Adenine, Thymine, Guanine, and Cytosine.
What can Punnett Square show?
It can show the prediction of offspring Genotypes.
What are the types of mutations?
Substitutions, Deletions, Insertions, and Inversions.
One preparation of Meiosis?
G1 Phase: Cell growth and normal metabolic activities
S Phase: DNA replication (chromosomes are duplicated)
G2 Phase: Continued growth and protein synthesis Accumulation of enzymes and proteins for cell division
What is the Human Genome Project?
An international research initiative was launched in 1990.
Where is DNA stored?
It is stored in chromsomes.
What are the four types of Punnett Square?
Monohybrid Cross, Incomplete dominance, Codominant Traits, X-linked traits.
What is one effect of Mutations?
Some mutations can lead to genetic disorders.
What are the 8 stages of Meiosis?
What was the goal of the Human Genome Project?
To Determine the sequences of the 3 billion chemical base pairs.
What are the 3 parts that make up DNA?
A phosphate group, a sugar group, and one of the types of nitrogen bases.
How do you solve Punnett Square?
1. You have to determine the gentype of the parents.
2. Then write down the possible gametes for each parent.
3. Arrange the parents' gametes around the edges of a Punnett square.
4. Do the offsprings squares.
5. Make sure to Interpret the results.
What is the role of Mutations in Evolution?
It introduces genetic variation in populations.
What are the phases of Meiosis?
Prophase, Metaphase, Anaphase, and Telophase.
What is one importance of the Human Genome Project?
Enabled advancements in genetics and human biology.
What does the D stand for in DNA?
Deoxyribose
What can Punnett Square predict?
It can predict the percentages of phenotypes in the offspring of a cross from known genotypes.
What are the 4 main Mutations?
deletion, duplication, inversion, and translocation
What happens during Meiosis?
two rounds of cell division to produce four haploid cells from a single diploid cell.
What is CRISPR?
A groundbreaking gene-editing technology discovered in bacteria.
