Subunit of DNA
Sugar in Dna
Four bases in DNA
Adenine, Guanine, Cytosine, Guanine
Adenine, Guanine (Two rings)
Cytosine, Thymine (One ring)
Adenine+ Thymine, Cytosine+ Guanine
Held together by hydrogen bonds
Held together by covalent (phosphodiester) bonds
Composed of DNA, a heritable factor that controls a specific characteristic
One specific form of a gene differeing from other Alleles by one or a few bases only and occupying the same gene cocus as other aleles of that gene
The whole genetic information of the organism
A change in the base sequence of an allele
Sickle Cell Anemia
Cells become sickle shaped, cant hold as much oxygen, leads to necrosis of the tubules, kidney damage or failure and possible death
Sickle Cell mutation
Changes a single base (T Replaces A)
Repeating set of events that make up life of a cell
Cell grows and matures, performs normal differentiated functions: Protein Synthesis, respiration, gylcolysis, transcription
Cell prepares for division, mitochondria and chroloplast replication
Cytoplasm divides to form two cells
Programmed cell death
Chromosomes line up at the equator
Sister Chromosomes seperate and move to opposite poles
Chromosomes start to return to chromatin and nucleus starts to return
Growth and Embroyonic development
This involves increasing the number of differientated cells
Dead or damaged cells are replaced by new cells
