What is the function of DNA?

DNA carries the genetic information for making proteins

what is a gene?

its a section of DNA which codes for protein.

The sequence of DNA bases determines what?

The sequence of amino acids in a protein

what does mRNA carries what?

it carries a complementary copy of the genetic code from the DNA in the nucleus to a ribosome where the protein will be made from amino acids.
