What is a primary and secondary cause of a genetic mutation?Slide3
DNA replication questionsWhy is DNA replication so important?
Life processes, growth, repair etc.
In what part of the cell cycle does DNA replication occur?
interphase
What enzyme brings in the new DNA nucleotides that form complimentary pairs with the old DNA strand?
DNA polymerase
What is a primary and secondary cause of a genetic mutation?
Environmental factors affecting the base pairs (code)Slide4Slide5Slide6
Protein Synthesis Vocabulary
Genetic code
(gene & protein building block sequence)
Transcription
(copying code)
Codon
(3 nucleic acid bases)
Translation
(translates 3 nucleic acids into amino acid)
Ribosome
(where translation occurs, it moves along the
Mrna
)
mRNA
(the messenger that brings code out of nucleus)
tRNA
(carries amino acid and its anticodons pair up with
codons bringing the amino acid into position)
AUG
– the start of a gene (codon)UAA,UAG,UGA – stop Slide7
Protein Synthesis Questions
What happens when a protein is
mis
-folded?
What is meant when a gene is said to be expressed?
In what organ is there a high number of expressed genes? Why do you think this is so?Slide8
Protein Synthesis Questions
What happens when a protein is
mis
-folded
?
It is threaded through a proteasome to be refolded or destroyed if too abnormal. A
mis
-folded protein can cause disease
What is meant when a gene is said to be expressed
?
When it has been transcribed & translated into a protein
In what organ is there a high number of expressed genes? Why do you think this is so
?
T
he brain and the liver because they carry on so many biochemical reactions they need more proteins.Slide9
