Pedigree
A diagram or chart that traces the inheritance of a trait over several generations
Pedigree
What does "Fitness" in biology mean?
Ability of an organism to reproduce and pass on their genes to the next generation
How many PAIRS of chromosomes does a typical human body cell have ?
23 Pairs
Shape of DNA is _______ _______
Double Helix
A full set of human chromosome is called _________
Karyotype
a.What Shape represents males in a pedigree
b. What shape represents females in a pedigree
c. How are affected individuals represented in a pedigree
a. Square
b. Circle
c. Shaded square or circle
Evolution is _______ over time because ______ _______ has occurred.
change ; Natural Selection
What is the correct order to make Protein?
DNA ------> RNA --------> Protein
What are the two steps of protein synthesis?
Transcription (Copying) and Translation (turn genetic code into protein)
If the series of bases in one strand of a DNA molecule is ATG CAT GAA, what are the bases of the opposite strand?
TAC, GTA , CTT
Why are there no carriers in a Dominant trait
Example : Brown eyes- B - dominant allele
Blue eyes - b - recessive allele
BB - Brown eyes ; Bb -brown eyes
Because in the trait the Dominant allele is always expressed , it cannot be hidden.
Any change in genetic code is called _________
Mutation
How many bases make up a codon (the code for amino acid)
3
This nucleic acid carries instructions for making proteins from the nucleus to the cytoplasm.
Hint: messenger
m RNA
Cells use amino acid to make ________
Protein

Insertion or deletion of bases are called Frameshift mutations. They are likely to be harmful , why?
The type and number of amino acid formed will be changed and therefore a wrong protein will be made.
Which type of RNA has amino acid attached to it
Hint: to turn Genetic code to a protein
tRNA
DNA is made of repeating units of _________
Which are made of ________ , ________ and _______
Nucleotide ;
Sugar , Phosphate and a base
What base does RNA have that DNA does not
RNA has U instead of T
In DNA : A pairs with T
In RNA : A pairs with U
