Random
100
The in between period in the life of a cell
What is the role of interphase?
100
It "unzips" between its paired bases and then new bases pair with the bases on each old strand.
During DNA replication the DNA does what?
100
A threadlike structure of nucleic acids and protein found in the nucleus of most living cells
What is a Chromosome?
100
An animal cell.
in what kind of cell is a furrow found in?
100
Growth means more work for transporting nutrients across the cell membrane and DNA overload.
Explain the problems that growth causes for cells.
200
True.
True or False: If a normal cell divides, then it has grown to full size.
200
A spiral or a twisted ladder.
What is the shape of a DNA molecule?
200
the cytoplasm splits in two and the cell divides.
What happens during cytokinesis?
200
Mitosis and Cytokinesis.
What are the two main stages of cell division?
300
One cell would have no DNA.
What would happen if a cell's DNA were not copied before cell division?
300
Thymine goes with Adeline and Guanine goes with Cytosine.
What nitrogen base goes with Adeline and what nitrogen base goes with Cytosine?
300
The chromosomes line up across the center of the cell.
What happens during Metaphase?
300
Cell plate is the structure found inside the dividing cells of terrestrial plants and some algae.
What is a cell plate?
300
The spindle fibers help separate the chromosomes.
What is the most significant role of the spindle fibers during mitosis?
400
Volume.
Which increases more rapidly: surface area or volume?
400
Adeline, Thymine, Cytosine, and Guanine.
What are the 4 nitrogen bases?
400
The centromeres split.
What happens during Anaphase?
400
Plants do not have centrioles just centromeres. Animal cells have centrioles so spindle fibers is one of the differences.
What are the differences between cell division in plant cells and in animal cells?
400
Two threadlike strands into which a chromosome divides longitudinally during cell division.
What are chromatids?
500
Deoxyribose
DNA is made up of what sugar?
500
The sister chromatids reach opposite poles. The small nuclear vesicles in the cell begin to re-form around the group of chromosomes at each end.
What happens during telophase?
500
It is the indentation of the cell's surface that begins the progression of cleavage.
What is a Furrow?
500
The centromere is the point of attachment of the chromatids.
what is a centromere?
