DNA Structure
The shape of DNA
What is a double helix?
What is DNA's purpose?
The instruction manual
What is a mutation?
A change in the genetic sequence
If a template strand is
AATTCC, what is the pairing strand?
TTAAGG
What is one use of gel electrophoresis?
paternity testing, solving a crime, john doe
In DNA, adenine pairs with
Thymine
What is a Codon
group of Three nucleotide (ATC) that act as words for the instruction manual
A mutation where one nucleotide is substituted for another
Substitution Mutation
Which mutations often cause the most problems and why?
Deletion and Insertion due to frame shift or causing all codons after it to change
What letter is different in RNa from DNA
Uracil or U
A nucleotide is made up of what 3 parts?
Phosphate, sugar, and base
Does one strand of DNA contain all of our genes?
YES
What does an insertion mutation do to the sequence?
Adds a new nucleotide or base to the sequence
What parts of the nucleotide makes up the backbone and ladder rungs of DNA?
Backbone= phosphate and sugar
Rungs= Base Pairs
When insulin is made, they use the technique called?
gene splicing
What does DNA stand for?
Deoxyribonucleic acid
Is all DNA made up of the same thing?
Yep!
Which mutation removes a nucleotide or base from the sequence?
Deletion
Which Cells have Identical DNA?
ALL, except reproductive cells
Who discovered inheritance, dominance and recessive?
Mendel, a monk
The sub-units of DNA
Nucleotide
What is different between our DNA and that of a snake or even a plant?
The order of the DNA structure
This mutation can cause a lot of problems if it happens in the right place.
substitution
If there is 40% of cytosine, how much Adenine is there?
10% Adenine
Why do my kingsnakes not look the same?
2 things: 1. mutations that cause a change in the genetic sequence
2. We all have slightly different genes, alleles, due to inheriting different ones for our parents. This means we also will look different than our parents too.
