DNA
What are the four nucleotides in DNA?
A, T, C, G
Where at in the cell does transcription occur?
Nucleus
Where at in the cell does translation occur?
on the ribosome
What are the two main categories of mutations?
Substitutions (point) and frameshift
Complimentary DNA strand for TATGCTAAC
ATACGATTG
Where must DNA live in the cell?
Nucleus
What is the product of transcription?
mRNA
What is the product of translation?
Protein
Which mutation changes the amino acid?
Missense
Single stranded, not complex and has the base Uracil.
RNA
What makes up the backbone of DNA?
Sugar and phosphate.
Where do we get the code for the mRNA strand?
DNA
Which type of RNA reads the message from mRNA?
rRNA
Which mutation does not change the amino acid?
Silent
The process of making mRNA from a DNA template in the nucleus.
Transcription
Why can DNA not leave the nucleus?
It is too big
Where does mRNA travel after transcription?
to the ribosome
Which RNA carries the amino acids needed to the protein chain?
tRNA
Which mutation gives a STOP codon?
Nonsense
The process of making a protein from an mRNA message on the ribosome.
Translation
What are the three parts of the nucleotide?
Transcribe the following DNA in mRNA
ATT-CGC-AGC
UAA-GCG-UCG
Translate the following mRNA into amino acids.
UAA-GCG-UCG
STOP-Ala-Ser
Looking at the following strands and identify what mutation occurred and where.
ATT-CGC-AGT
ATC-GCA-GT
T was deleted
Why is protein synthesis important?
Because it is how all living things survive
