Unit 1.3 DNA and the production of proteins Flashcards
1
Q
What is the structure of DNA
A
DNA is a double-stranded helix. It has two backbones which are held together by complementary base pairs
2
Q
What does DNA do
A
DNA carries the genetic information for making proteins
3
Q
What are the bases in DNA
A
Adenine - Thymine
Cytosine - Guanine
4
Q
What do the four bases in DNA make up
A
The genetic code
5
Q
What does the order of bases in DNA determine
A
The order of bases in DNA determines the sequence of amino acids in proteins
6
Q
What is a gene
A
A gene is a section of DNA which codes for a protein
7
Q
What is Messenger RNA (mRNA)
A
Messenger RNA is a molecule which carries a complementary copy of the genetic code from the DNA in the nucleus to a ribosome in the cytoplasm. Where a protein is assembled from amino acids
