DNA and the Production of Proteins Flashcards
(5 cards)
1
Q
what is dna
A
dna carries genetic information to make proteins. it has a distinctive double stranded helix structure which is held by complementary base pairs
2
Q
what is the structure of dna
A
each base is attached to a phosphate molecule and a sugar molecule to make a molecule of dna. this is called a nucleotide. these nucleotide all join together. matching the complimentary base pairs, to form a strand of dna
3
Q
what is protein synthesis
A
mRNA is a molecule which carries a complementary copy of the genetic code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids
4
Q
what is a gene.
A
a section of dna which codes for a protein
5
Q
what is mRNA
A
determines the order of amino acids
