3. DNA Flashcards
1
Q
What shape is DNA
A
Double stranded helix
2
Q
Where is DNA found
A
In the nucleus, but mRNA carries a copy out to ribosomes so protein synthesis can occur
3
Q
What holds DNA together
A
Complementary base pairs:
Adenine and Thymine
Cytosine and Guanine
4
Q
What do the four bases code for
A
The sequence of amino acids, which determines the structure and function of proteins
5
Q
What is a gene
A
A section of DNA
6
Q
What are the strong bonds that link DNA
A
Peptide bonds
7
Q
Where is mRNA made
A
In the nucleus
8
Q
What do mRNA molecules do
A
Carries copy of DNA to a ribosome for it to read, another copy is then assembled
