2. RNA & PROTEIN SYNTHESIS

3. 42. RNA Sugar Ribose Bases A,U,C,G Number of strands 1 strand
Where in the cell
Cytoplasm
Function
Codes for proteins

4. 45. What the three types of RNA and what are their functions?
mRNA – carries message from DNA
rRNA – makes up the ribosome
tRNA – transfers amino acids to the ribosome

5. #35
Transcription is the process of making mRNA from the DNA in the nucleus.

6. Translation #38 Translation is the making of the protein from the mRNA
Occurs in the cytoplasm at the ribosome
The mRNA codon codes for an anticodon on the tRNA
The tRNA delivers the correct amino acid to build the polypeptide chain. Which will then become the protein

8. #36 & 37
In RNA the base thymine is replaced with uracil so if the DNA is A-G-C-C-A-G , the RNA will be
U-C-G-G-U-C
A codon is a group of 3 bases that code for an amino acid.

9. #39 & 40
To determine the amino acid sequence you use a RNA codon chart
Look up the mRNA codon
UCG codes for
SER
GUC codes for
Val
40. The amino acids are held together with peptide bonds (hince the polypeptide chain)

10. MUTATIONS 43. What is a mutation? Change in genetic sequence
Frameshift mutations
Insertion
Deletion
Point mutations
Substitution
44. A mutation must be in the gamete if it is passed on to the next generation

11. GENE EXPRESSION #41
Not all genes are turned on. In some cells parts of the DNA will be turned on, but in other cells the same part will be turned off.
This results in differentiation. The ability of cells to behave differently.
This is why even though all of our body cells have the exact same DNA, they don’t all function the same way.
