Mutations
One reason that mutations are biologically important
They can result in new varieties of gene combos in a species
CTT TAA TCG becomes CTT TAA TAG is an example of this type of mutation.
What is Substitution?
List the Central Dogma that shows the relationship between DNA and an organisms traits.
DNA --> RNA --? Amino Acid/Protein --> Trait
What is DNA --> RNA --> PROTEIN
The correct sequence of the following is:
1. Alteration of the base sequence on a strand of DNA
2. Exposure to Radiation
3. Cell Function Changes
4. A new protein is synthesized
2 - 1 - 4 - 3
Exposed to Radiation -> base sequence alters -> new protein made --> cell function changed
What is a base sequence?
If a DNA is 20% Guanine, it would have this percentage of Cytosine.
What is 20%.
Where is the ribosome?
The mutation where one base is replaced
What is substitution?
The two steps for protein synthesis
What are transcription and translation?
The place RNA is found
Where is chromosome/ribosome?
Proteins are made of this
What are amino acids?
The mutation where one extra base added
What is insertion?
Name the base pairs for Transcription
A
T
C
G
What are:
U
A
G
C
The complementary mRNA sequence for:
GTTACA
CAAUGU
The # of nucleotides for 1 amino acid.
The # of nucleotides for 3 amino acids.
What is 3?
What is 9?
The mutation where there is a removal of a base
What is deletion?
What is the nucleus?
The three components found in DNA and RNA.
DNA sequence is ATC, the mRNA codon will be:
And the amino acid will be:
mRNA = UAG
Amino Acid: STOP
