One of the four base chemical compounds that make up the nucleotides.
What is Adenine?
Nucleotides = A______, Cytosine, Guanine, & Thymine
A stage in the process of Cell division when the sister chromatids separate and move to opposite poles of the cell.
What is Anaphase?
Ana and her sister Chromatids argue and withdraw to separate poles in her cell
A type of prokaryotic cell.
What is Bacteria?
A one-celled organism of the Monera Kingdom. Types: round, spiral or blue-green
A distinctive or special feature of an organism.
What are Characteristics?
Helps us classify living things.
A chemical structure made up of molecules from two or more elements.
What are Chemical Compounds?
Ex. NaCl - Sodium Chloride
In the process of cell division, each chromosome is replicated exactly; These two copies are called sister ____?______.
What are Sister Chromatids?
Pulled to opposite poles in Mitosis but in Meiosis they don't separate at their centromeres.
An exact copy of an organism by genetics.
What is Cloning?
The 1st Genetic ________ was a sheep.
One of the four base chemical compounds that make up the nucleotides.
What is Cytosine?
Nucleotides = Adenine , _________, Guanine & Thymine
An organism in the earliest stages of development in the uterus
What is an Embryo?
Ex. a seed contains all the genetic material for a new plant
Proteins that catalyze chemical reactions in organizms.
What are Enzymes?
Chemicals made by digestive system which speed up digestion of food.
It is not the composition of the genes, but the way that they are sequenced that provide the hereditary information of the organism.
What are Gene Sequences?
The arrangement of genes on chromosomes
One of the four base chemical compounds that make up the nucleotides.
What is Guanine?
Nucleotides = Adenine, Cytozine, ________ & Thymine
A stage in the process of cell division in which the nucleotides and gene sequences are replicated.
What is Interphase?
Inter means between & phase means division.
A stage in the proces of cell division when the sister chromatids line up along the central axis of the cell.
What is Metaphase?
Meta means with, after, beyond or change while phase means division. (after division)
The egg of the female.
What is Ova?
female reproductive material produced in ovaries
A stage in the process of cell division in which the sister chromatids condense and thicken; at this stage, the chromosomes are visible
What is Prophase?
A stage in the process of cell division in which the sister chromatids condense and thicken; stage at which chromosomes are visible.
What is Prophase?
Homologous chromosomes pair along their lenth and cross over after condensing & nuclear envelope breaks down.
Cells that have the ability to develop into different kinds of cells.
What are Stem Cells?
Cells used in fighting cancer.
The final stage of mitosis when a nuclear membrane forms around the chromosomes each pole and the cell divides at its equator
What is Telophase?
Chromosomes gather at poles and cytoplasm divides to form two new cells
One of the four base chemical compounds that make up the nucleotides.
What is Thymine?
Nucleotides = Adenine, Cytozine, Guanine & __________.
The process of cell division.
The process of sexual reproduction.
What is Mitosis?
What is Meiosis?
In M_______ the 2 cells (daughters) that are produced are EXACTLY the same genetic makeup as original mother cell while in M________ the cells are not the same at all but new types of cells = genetic diversity.
