Which model of base pairing is correct for DNA?

A=T and C=G

A=C and T=G

A=T and G=U

A=G and T=C

What mutation has occurred here?
T-G-A-C-C-A
T-G-A-G-C-A

Substitution

Deletion

Insertion

Frameshift

In a molecule of double-stranded DNA, the amount of Adenine present is always equal to the amount of

cytosine

guanine

thymine

uracil

What is a codon?

It is a three letter section of bases that are read by ribosomes to identifying the amino acids which will go into a protein

They are the codes on the DNA (hence "code-on"

It is a type of mutation that occurs when there has been a substitution, deletion or insertion

A series of 3 letters found on tRNA which transfers the amino acid to the ribosome

Why are insertion and deletion mutations so harmful?

They change all of the codons from the mutation on down the line, which changes the amino acid sequence

They insert things that an organism doesn't need.

They often delete things that organisms need.

Insertion and deletions are not any more harmful than substitution mutations.

ATTTGAGCC- Original
ATTGAGCC - Mutated
The example above is an example of a

Insertion- Frameshift

Deletion- Substitution

Deletion -Frameshift

All of the above
