Terms in this set (42)
division of the nucleus in eukaryotes
the division of the cytoplasm in eukaryotes
a series of events cells go through as they grow and divide
divided into three phases: G, S, and G2. the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.
The first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears.
The second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers
The stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle
The final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed
a group of proteins that regulate the timing of the cell cycle in eukaryotic cells
a disorder in which some of the body's cells lose the ability to control growth
the scientific study of heredity
when plants produce offspring identical to themselves
a specific characteristic, such as height or seed color
the offspring crosses between parents with different traits
factors that are passed from one generation to the next
one of two different gene forms that control each trait
the likelihood that a specific event will occur
a diagram that models genetic crosses
organisms that have two identical alleles for a particular trait
organisms that have two different alleles for the same trait
when one allele is not completely dominant over another
when both alleles appear as part of the phenotype of the heterozygous offspring
genes that have more than two alleles
a single trait that can be controlled by more than one gene
the process in which the number of chromosomes per cell is divided in half through the separation of homologous chromosomes in a diploid cell
a cell that has both sets of homologous chromosomes. means "two sets"
a cell that has only one set of chromosomes
data used to find the distance between genes in a chromosome
a "twisted ladder"
bonds between certain base pairs: adenine and thymine, guanine and cytosine.
units made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base
process in which a DNA molecule separates into two strands
the type of RNA that has the instructions for making amino acids and making proteins
the type of RNA that makes up the major part of ribosomes
the type of RNA that carries each amino acid to the ribosome according to the coded message in messenger RNA
process in which part of the nucleotide sequence in DNA is copied into a complementary sequence in RNA
a group of three nucleotides
mistake made when cells copy their own DNA
changes in a single gene
gene mutation involving changes in one or a few nucleotides
when a nucleotide is added or removed
a change in the number or structure of chromosomes
