DNA
A molecule of DNA is composed of __________ strands.
What is 2?
DNA is located in this cell organelle.
What is the nucleus?
This is the stage of the cell cycle where the cell spends most of its life (about 80%).
What is interphase?
There are this many stages in mitosis.
What is four?
This is the type of bond that holds together the two strands of DNA.
What is a hydrogen bond?
A DNA nucleotide is composed of a phosphate, nitrogenous base, and this.
What is a sugar?
This is the monomer of DNA.
What is a nucleotide?
This is the stage of the cell cycle where DNA replication happens.
What is S phase?
This is one reason a cell may not divide.
What is a DNA error, not enough space, not enough nutrients, etc.
This is the stage of mitosis where daughter chromosomes are pulled to opposite sides of the cell.
What is anaphase?
This is the name for the shape of DNA.
What is a double helix?
If a strand of DNA is 30% Guanine, then this is the percent of Cytosine.
What is 30%?
This is the stage of the cell cycle where the number of organelles doubles.
What is G2?
This is the stage of the cell cycle where the cytoplasm divides.
What is cytokinesis?
This is the type of bond that holds together the nucleotides in a strand of DNA.
What is a covalent bond?
This is the most organized form of DNA.
What is a chromosome?
DNA is a type of macromolecule called this.
What is a nucleic acid?
During this stage of mitosis, the chromosomes line up at the equator of the cell.
What is metaphase?
Chromosomes relax back into this form of DNA by the end of cytokinesis.
What is chromatin?
If a cell with 24 chromosomes goes through mitosis, this is how many chromosomes will be in each of the daughter cells.
What is 24?
If a molecule of DNA has 20% Adenine, this is the percent of Guanine.
What is 30%?
This is the name of the enzyme that breaks apart the two strands of DNA during DNA replication.
What is helicase?
During this stage of the cell cycle, centrioles begin to form spindle fibers.
What is prophase?
These are the stages of mitosis, in order.
What is prophase, metaphase, anaphase, and telophase?
This is the organelle that holds together two sister chromatids.
