DNA stands for ___________________ .
What is deoxyribonucleic acid?
This is the first step in DNA replication. (not the name of the enzyme)
What is DNA unzips and unwinds?
The phase the cell spends most of it's time in.
What is interphase?
This is the correct order of the four steps in mitosis.
What is prophase, metaphase, anaphase, and telophase?
These speed up cell division. They are like the “accelerator” in a car
What are oncogenes?
The backbone of a DNA molecule consist of these two components; one of which has a slight negative charge, one of which has 5 carbon atoms. (list in that order)
What is phosphate and sugar (deoxyribose)?
The name of the enzyme that unzips and unwinds the DNA molecule
What is helicase?
The two steps to binary fission are? What undergoes binary fission?
What is DNA Replication, cell split prokaryotes
This is the phase of mitosis where chromatin gets "converted" to supercoiled chromosomes and the nuclear envelope begins to break down.
What is prophase?
Anything that has the potential to cause cancer can be referred to by either of these two terms.
What are carcinogens or mutagens?
The 4 nitrogenous bases in DNA are:
What is adenine, guanine, cytosine, thymine
The enzyme that adds new nucleotides to the DNA template strand.
What is DNA polymerase?
Instead of creating a cleavage furrow to separate, a plant cell creates this.
What is a cell plate?
1/2 half of a double stranded chromosome.
What is a chromatid?
These are 3 common causes of cancer discussed in class.
What are viruses, UV radiation, and harmful chemicals?
The type of organic molecule found in DNA.
What is nucleic acid?
If a gene's bases are 22% adenine, what percentage of the bases would be cytosine?
What is 28%?
This is the phase of the cell cycle where organelles copy themselves in order to prepare for division.
What is G2?
This is the phase where the centrioles and spindle fibers break the connection at the centromere and pull apart the double stranded chromosome.
What is anaphase?
This is the term for the "brakes" for cell division.
What are tumor suppressor genes?
Nitrogenous bases with a 2-ring structure.
What are purines?
If a gene's bases are 14% thymine, what percentage of the bases would be guanine?
What is 36%?
These are the shorthand terms (letter symbols) for ALL the phases of the cell reproduction cycle that are not included in mitosis.
What are G1, S, G2, AND C?
What is the definition of mitosis?
What is the active splitting of the nucleus?
Choose the order that represents the correct sequence of phases of the cell cycle.
A) A-J-G-K-M C) F-L-B-M-K
B) A-B-C-E-G D) E-B-C-M-K Also, what type of cells are these?
C!
Plant Cells!
