DNA
Where is DNA stored in a Eukaryotic Cell?
in the nucleus
What are the 6 stages of the Cell Cycle in order?
Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
How many daughter cells come from Mitosis and how many from Meiosis?
Mitosis 2
Meiosis 4
Match the term with the example: Homozygous Dominant, Homozygous Recessive, and Heterozygous.
Bb BB bb
Homozygous Dominant BB
Homozygous Recessive bb
Heterozygous Bb
What is a Punnett Square?
What nitrogenous base pairs with Adenine?
Thymine
Which stage has the chromosomes lined up in the middle of the cell with spindle fibers attached?
Mitosis
What is a genotype? Give an example
The actual genetic make up represented by letters.
Ex: BB
If you cross GG and gg, what percentage of the offspring will be Homozygous?
0%
What two materials make up the backbone of DNA?
Sugar and Phosphate
Which stage of the Cell Cycle do the chromosomes become shorter and thicker?
Prophase
How many times do cells divide in Mitosis and how many in Meiosis?
Mitosis 1
Meiosis 2
What is a phenotype? Give an example
The physical appearance of an organism.
Ex: Blue Eyes
If you cross Bb and bb, what percent of the offspring will show the dominant trait?
50%
What is a section of DNA called?
A gene
Cytokinesis
Which process results in haploid daughter cells instead of diploid?
Meiosis
What is the definition of Heredity?
passing genes from parent to offspring
H = Curly hair h = Straight hair
Cross somebody who is heterozygous with somebody who is homozygous dominant. What is the chance their offspring will have Curly Hair?
100%
What does DNA stand for?
Deoxyribonucleic Acid
Why is it important for cells to divide?
So living organisms can grow and reproduce.
What is the genetic difference between the offspring of sexual reproduction vs asexual reproduction?
Asexual creates identical offspring
What is an Allele?
A different form of a specific gene.
Cross somebody who is heterozygous and tall with somebody who is short. What is the chance that their offspring will be short?
50%
