Messenger RNA (mRNA)
Type of RNA that encodes information for the synthesis of proteins and carries it to a ribosome from the nucleus
Single Stranded, has ribose as a sugar
Contains the nucleotides: A, G, C, U (uracil)
Uracil replaces Thymine
Complementary binding
DNA Review
DNA is double stranded.
Nucleotides: A, T, G, C
Contains a phosphate and deoxyribose sugar on the sides.

Protein Synthesis
Happens in two main steps
Transcription
Translation
Starts in the nucleus and finishes in the cytoplasm of a cell
Transcription
First step of protein synthesis
DNA is "unzipped" by RNA polymerase (an enzyme)
Nucleotides that are floating in the nucleus match up complementary to the nucleotides on DNA
