what does the m stand for in mRNA?
messenger
what structure is made up of genes?
chromosome
what is the function of mRNA?
acts as a complementary copy of the DNA code and carries a copy of the genetic code from the DNA in the nucleus to a ribosome in the cytoplasm
what does the base sequence of DNA determine?
the base sequence determines the amino acid sequence of the protein
name the 4 DNA bases?
adenine, thymine, guanine, cytosine
what are the complementary base pairs?
C + G
T + A
location of DNA in a cell?
nucleus
what shape is a DNA molecule?
double helix
what is a gene?
a gene is a section of DNA which codes for protein
name the structure where a protein is assembled?
ribosome
where is dna located?
in the nucleus
why is the base sequence important?
determines the order of amino acids in the protein
what is a gene?
a section of dna which codes for a protein
what is mRNA

what happens at the ribosome?
mRNA is read into groups of 3
