Cell Cycle
What is the cell cycle?
Define Zygote
A fertilized egg
Define Chromosomes
Strands of tightly wound DNA
The study of heredity is called what?
Genetics
What was the experiment Mendel conducted?
He cross-pollinated pea plants with opposite forms of a trait
Name all of the phases of the cell cycle
Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
What is Meiosis?
The form of cell division by which gametes, with half the number of chromosomes are produced
Define DNA
Genetic material that carries information about an organism and is passed from parent to offspring
Define Homozygous and Heterozygous and give me examples
Homozygous: Has 2 identical alleles for a trait. ex GG ff HH tt KK.
Heterozygous: Has 2 different alleles for a trait. ex Ff Gg Hh Kk Ii
Define Purebread
An organism that always produces offspring with the same form of a trait as the parent
What is the purpose of Mitosis?
To produce new cells for growth and repair that are identical to the parent cell
How many chromosomes does a haploid have? Diploid
23;46
What is the structure of DNA? What is it made out of?
Double Helix; 4 nitrogen bases (NAME THEM)
Define Dominant allele
An allele whose trait always shows up when the allele is present
Define Phenotypes
Physical appearances or visible traits
What are the 2 main components of the cell cycle?
Interphase and Mitosis
How many daughter cells comes out of Meiosis? Are they identical?
4 unidentical haploids
Who observed the structure of DNA?
Rosalind Franklin
Define recessive allele
An allele whose trait is masked or covered up whenever the dominant allele is present
Define Genotypes
Genetic makeup or allele combinations
What are the 3 stages of the cell cycle?
Interphase, Mitosis, and Cytokinesis
Two
The sides of the double helix are made out of what?
Sugar and Phosphate molecules
Whats the difference between genes and allele?
Genes are factors that control traits and alleles are different forms of a gene
Draw the Mendel experiment punnet square and figure out BOTH generations of pea plants correctly
