Biology Honors Unit 4: DNA and the Cell Cycle
Terms in this set (42)
Deoxyribonucleic Acid (DNA)
A complex molecule containing the genetic information that makes up the chromosomes.
A building block of DNA, consisting of a five-carbon sugar covalently bonded to a nitrogenous base and a phosphate group.
Scientist that showed a "transforming factor" can be passed from one species of bacteria to another.
Watson and Crick
The scientists credited with establishing the structure of DNA.
Woman who generated x-ray images of DNA, she povided Watson and Crick with key data about DNA
Complimentary Base Pairing Rules
Concept that explains hydrogen bonding between particular bases in DNA, thymine (T) pairs with adenine (A), and guanine (G) pairs with cytosine (C)
The nitrogen base that pairs with Thymine in DNA
The nitrogen base that pairs with Adenine in DNA
The nitrogen base that pairs with Guanine in DNA
The nitrogen base that pairs with Cytosine in DNA
After DNA replication, each newly created DNA strand contains one old and one new strand in its double helix.
An enzyme that untwists the double helix of DNA at the replication forks.
Enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule; also proofreads the completed DNA strands.
A Y-shaped region on a replicating DNA molecule where new strands are growing.
A tightly wound bundle of DNA. This is how DNA is stored in the cell's nucleus.
Each half of the chromosome
Area where sister chromatids of a chromosome are attached
Shape of DNA
A part of the cell containing DNA
Deoxyribose, Phosphate, Nitrogen Base
Three subunits of DNA nucleotides
Bonds that form between pairs of nitrogenous bases and hold the two strands of a DNA double helix together
Bonds found between the sugar and phosphate subunits of DNA nucleotides; hold the backbone of the double helix together
A change in the nucleotide-base sequence of a gene or DNA molecule
Longest phase of the cell cycle; includes the G1, S, and G2 phases
Stage of mitosis where chromosomes become visible and the spindle apparatus forms
Stage of mitosis where chromosomes line up in the middle of the cell
Stage of mitosis where sister chromatids separate
Stage of mitosis where two new nuclei form in the cell
Division of the cytoplasm that follows mitosis
This forms in animal cells during cytokinesis
This forms in plant cells during cytokinesis
Stage during interphase where the cell grows in size
Stage during interphase where the DNA is replicated or copied
Stage during interphase where the cell prepares for division
Disease that results when cells do not respond to checkpoint control systems and continue to divide uncontrollably
Proteins that monitor the cell during the cell cycle
Mitosis (aka M-phase)
Type of nuclear division that makes two genetically identical diploid cells
Mitotic Spindle (Spindle Fibers)
Microtubules that pull chromosomes apart during mitosis
Process by which a cell divides into two daughter cells; includes mitosis and cytokinesis
Masses formed by cancerous cells
Prophase, Metaphase, Anaphase, Telophase
Stages of Mitosis in the correct order
G1, S, G2
Stages of Interphase in the correct order
