DNA Structure Cytosine and Guanine

always pair up.

Adenine and Thymine always pair up.

DNA Structure

DNAThe sequence of bases in DNA is the genetic code.

Sections of DNA are coded (instructions) for the cell to build proteins.

RNA Ribose

Nucleic Acid Single

backbone of Ribose sugar and Phosphate

RNA Nitrogen Bases

Cytosine, Guanine & Adenine are the same.

Uracil replaces Thymine Uracil always pairs

with Adenine.
