DNA and production of proteins Flashcards
What is the structure of DNA?
Double-stranded helix held together by complementary base pairs
What are the four bases in DNA?
Adenine, Cytosine, Guanine, Thymine
What are the complementary base pairs?
Adenine always pairs with Thymine and Cytosine always pairs with Guanine
What do the sequence of the four bases make up?
The genetic code of an organism
What does the DNA carry?
The genetic information to make protein molecules
What does the sequence of DNA bases in the genetic code determine?
The sequence of amino acids in the protein molecule
What is the difference between a gene that codes for insulin, and a code that codes for adrenaline?
The order of the bases
What is a gene?
A section of DNA which codes for a protein
What does Messenger RNA do?
Carries a complementary copy of the genetic code from the DNA in the nucleus, to a ribosome
In the ribosome the complementary copy is read, and the information is used for what?
To assemble proteins from amino acids
