What is the name for a female gamete?
Egg
How many types of Meiosis are there?
2
What does PMAT stand for?
Prophase, Metaphase, Anaphase, and Telophase
What do ribosomes make?
Proteins.
What enzyme breaks the hydrogen bonds?
Helicase.
What cell forms during fertilization?
Zygote
How many times does the original diploid cell divide?
Twice.
What is included in the Mitotic Phase?
Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
What organelles make ribosomes?
Nucleolous.
What does DNA polymerase do?
It brings nucleotides over to the original strands to make new strands.
True or False- a diploid cell is the amount of different types of chromosomes?
False
True or False- In meiosis one homologous chromosomes pair up and then separate?
True
What is the order of the cell cycle (just using the phases)?
Interphase, and Mitotic Phase
Where does the energy from the mitochondria come from to make APT?
Glucose.
What are nucleotides made of?
Phosphate, Deoxyribose sugar, and a Nitrogen base
What are the 3 types of genetic variation and what do each do?
Crossing over- when homologous chromosomes pair up during prophase and they exchange small bits of DNA. Independent assortment- when chromosomes go to opposite poles of the cell in Anaphase and chromosomes end up together at the poles from a matter of chance. Random union of gametes- two gametes unite to produce an offspring, a matter of chance when the union of gametes occur randomly.
True or False- Meiosis 1 and 2 have different phases that mitosis?
False
what is the order of the cell cycle (in depth)?
Growth Phase 1, Synthesis, Growth Phase 2, Prophase, Metaphase, Anaphase, Telphase, and Cytokinesis.
What are lysosomes function?
The cells garbage disposal, and recycling center.
What bases all pair together, and what is the saying ( the one Ms. Kesner came up with)?
Adenine pairs with Thymine, and Guanine pairs with Cytosine. AT GuCci
In meiosis each daughter cell has one chromosome from what type of pair?
Homologous pair.
When does meiosis occur?
It occers when a organism meets gametes.
Give a brief sentence on what each singular phase does?
G1- Cell grows rapidly and duplicates (some) organelles and proteins. S- DNA replication happens. G2- Gets ready to divide and finishes duplicating organelles and proteins. P- Nucleus breaks down and spindle fibers begin to form. M- Chromosomes align in the middle of the cell. A- Spindle fibers pull the chromosomes to opposite sides of the cell. T- Two nuclei form and the spindle fibers break down. C- The cytoplasm splits the cell into two daughter cells/ two identical cells.
What kind of jobs do plastids have?
Chorolaplasts, Chromoplasts, and Leucoplasts
What does semi conservative mean?
Consists of both something new ( the new DNA strand) and an original (the original DNA strand).
