Simple Inheritance
tthe passing on of physical or mental characteristics genetically from one generation to another
Heredity
DNA stands for:
Deoxyribonucleic Acid
What is a codon?
A group of three bases
What is a vestigial structure?
"unnecessary" leftover structures that no longer have a function
Occurs in the body cells
Mitosis
Physical characteristics like your hair or eye colour
Phenotypes
DNA is found in:
Found in chromosomes. In nucleus of the cell.
What does Adenine pair with? (full name)
Thymine
Evidence for comparative anatomy - what is the structure called?
Homologous structure - pentadactyl limb
Goes through two stages of division
Meiosis
Genetic characteristics
Genotype
DNA can be described as:
The blueprint of life
Name the four bases
Adenine
Thymine
Guanine
Cytosine
Evidence for geographical distribution - what animal where?
Finches on Galapagos island
How many pairs of chromosomes in a human?
23
the father of genetics
Gregor Mendel
One section of DNA - one base pair and the backbone
Nucleotide
What is a substitution mutation?
One base is substituted for another
DNA-DNA Hybridisation is used for what evidence?
Biochemistry
Mitosis spends most of its time in this stage
Interphase
Name the three allele pairings
Homozygous dominant
Homozygous Recessive
Heterozygous
Structure (shape) of DNA
Double helix structure
With a somatic (body cell) mutation affect offspring?
Not inherited
All evidence for evolution suggests we have...
a common ancestor
In mitosis, the chromosomes are pulled apart to form two identical sets during this stage
Anaphase
