The process by which cells reproduce
What is cell division?
Every species has a characteristic number of these in each cell.
What are chromosomes?
The term used for a cell that contains both chromosomes of a homologous pair.
What is diploid?
The three phases of the cell cycle.
What are interphase, mitosis and cytokinesis?
The two chromatids that are joined are often called this.
What are sister chromatids?
The process of nuclear division that reduces the number of chromosomes by half.
What is meiosis?
Information in the cell is contained in these. Shaun prefers Levis!!
What are genes?
The number of chromosomes found in humans.
What is 23 pairs or 46 chromosomes?
The notation used for a diploid cell.
What is 2N?
he 5 events in the cell cycle.
What are G1, S, G2 , Mitosis and Cytokinesis?
The sister chromatids are attached by one of these.
What is a centromere?
As tetrads form, portions of chromatids may be exchanged, either between the two homologues or between sister chromatids. This phenomenon results in the exchange of genes.
What is crossing over?
It is composed of DNA and protein, exists as thin, uncoiled strands and is found in cells that are NOT undergoing cell division
What is chromatin?
The two members of each pair of chromosomes are called this?
What are homologous chromosomes or homologues?
The term for a cell that has only one chromosome of each homologous pair.
What is haploid?
The three distinct phases in interphase
What are G1, S and G2?
These consists of two identical parts, each called a chromatid.
What are chromosomes?
When forming these sec cells, the cytoplasm is split equally between the four cells. All small but very energetic
What are sperm?
When DNA wraps around these (a group of specialized proteins) it is called a chromosomes.
What are histones?
This is one of the main factors that triggers cell division.
What is size?
Means container in latin.
What is cyto?
The phase when the cell doubles in size, and enzymes and organelles double in number
What is the G1 Phase of interphase?
The spindle fibers that extend from centriole to centriole.
What are polar fibers?
There name given to the viable egg produced
What is ootid?
The division of the cell nucleus in which the chromosomes in the parent cell divide into two identical sets.
What is mitosis?
The sequence of events that occurs in a cell from mitosis to mitosis.
What is the cell cycle?
Means movement in latin.
What is kinesis?
The phase when the DNA that makes up- the chromatin replicates.
What is the S phase?
The four phases of mitosis.
What are prophase, metaphase, anaphase and telophase?
Three of these are produced during the meiosis that creates one egg. They lack cytoplasm and its contents and they will disintegrate!!
What are polar bodies?
The general name of the phase that follows interphase.
What is mitosis?
These move away from each other, going toward opposite poles, of the cell during prophase.
What are centrioles?
These spindle fibers extend from the centromere to the centriole. Controls the movement of the chromosome
What are kinetochore fibers?
Cells spend most of their lifetime in this phase.
What is interphase?
This process usually takes place immediately after mitosis and is when the cytoplasm from the original cell splits and forms two new cells.
What is cytokinesis?
The production of offspring from one parent, without the union of gametes.
What is asexual reproduction?
