What are the 4 phases or the Cell Cycle?
Meiosis, Gap 1, DNA Synthesis, Gap 2
100
For every 1 cell to go through __________ 4 haploid cells are produced.
meiosis

Who studied genetics in peas? And why did they study peas instead of Pandas?
Mendel, Peas have a short easily controlled reproductive cycle with easily identified dichotomous traits. Panda's refuse to reproduce in captivity, all look alike, and take to long to mature and reproduce.
100
What are the two steps of DNA expression?
Transcription and Translation
100
What is a nucleosome?
DNA wrapped around proteins called histones
200
What happens when the Cell Cycle is disrupted? How does the cell prevent disruptions?
Cancer; check points in the progress of the Cell cycle which are controlled by inhibitors called RB and inhibitor in activators called CDK
200
What are the 5 steps of Mitosis?
prophase, prometaphase, metaphase, anaphase, telophase
200
What were Mendel's laws?
Law of Segregation Law independent assortment
200
What are the three steps of DNA translation?
Initiation, elongation, termination
200
What is a tetrad?
a pair of homologous chromosomes
300
What is the difference in offspring of asexual reproduction compared to sexual reproduction?
Asexual = genetically identical to the parent and other offspring Sexual = varies genetically from parent and other offspring

5. During Meiosis, how many times does a cell go through Metaphase? How does it differ each time? a. Twice b. In Metaphase I the homologous pairs align at the equatorial plates c. In metaphase II individual chromosomes align on the equatorial plate; similar to metaphase in mitosis, except the cell is haploid
Twice In Metaphase I the homologous pairs align at the equatorial plates In metaphase II individual chromosomes align on the equatorial plate; similar to metaphase in mitosis, except the cell is haploid

What is the particulate theory?
each plant has 2 particles for each character, one from each parent. Information of gametes is haploid: only one particle from each parent is given to each gamete
300
What is AUG and what does it do?
The start codon-- indicates signal for translation
300
define true breeding
when an organism has been interbred so many times that it only shows a single trait
400
What are the four basic steps of cellular division in Prokaryotes?
Reproductive Signals, Replication, Segregation, Cytokinesis.
400
The exchange of genetic material between homologous pairs occurs at the ________ and is called ________.
chiasmata, crossing over
400
Traits such as human hight and pig weight are what types or traits?
quantitative traits
400
What are the complementary strands of DNA to the lagging template strand called?
Okazaki Fragments
400
what is the A-Site?
the ribosomal site with binds with a charged tRNA molecule
500
During Eukaryote reproduction two __________ meet to form a ___________.
gametes, zygote
500
How does metaphase differ in Mitosis and Meiosis reproduction?
Meiosis cells go through metaphase twice, first separating the homologous pairs and second separating the sister chromatids. Mitosis goes through metaphase once, to separate the sister chromatids.
500
A homozygous recessive pink butterfly reproduces with a heterozygous blue butterfly, what is the phenotypic ratio of offspring?
2 pink : 2 blue
500
What did Watson and Crick discover?
The anti-parallel double helix structure of DNA
500
What is an Ori?
origin of replication on a template strand of DNA
