Structure of dna
DNA is a double stranded helix that is held together by complementary base pairs.
What is held in dna
The DNA carries pieces of coded genetic information
What are the 4 bases that make the genetic code
Adenine (A) ● Thymine (T) ● Guanine (G) ● Cytosine (C
Complementary base pairs
Adenine always pairs with Thymine (A-T) Guanine always pairs with Cytosine (G-C
What does the sequence of bases in dna determine
The sequence of bases in a DNA molecule can determine the order of the amino acids in a protein molecule.
What is a sequence of bases called
A sequence of bases on DNA that codes for a protein is called a gene.
mRNA
messenger RNA (mRNA) is made in the nucleus and carries a complementary copy of the DNA base sequence of a specific gene to a ribosome. This is where the protein will be assembled from amino acids.
