DNA mRNA
1.) Longer Shorter
2.) Thousands of millions of genes 1 gene
3.) Double stranded [ helix] Single-Stranded
4.) Bases- AGCT Bases AGCU [ U= Uracil]
5.) Stays in the nucleus Produced in the nucleus and goes to the cytoplasm and to the ribosome
6.) Produced in replication Produced in transcription
7.) Deoxyribose sugar Ribose Sugar
When it is time to replicate, the DNA unzips (at the hydrogen bonds).
Replication
New complementary nucleotides move in to match BOTH halves of the DNA and form hydrogen bonds with the old nucleotides.
Replication
The finished product is: 2 identical DNA molecules that are ½ new and ½ old.

Transcription
Cells gets the message that a protein needs to be made and a portion of DNA unwinds, exposing the gene that needs to be copied.
Transcription
Nucleotides move in to one half of the unzipped DNA. These nucleotides have ribose sugar and uracil instead of thymine.
Transcription
The mRNA leaves the nucleus and goes to the ribosome. The DNA rezips.

Translation
The mRNA goes to the ribosome.
Translation
The mRNA tells the ribosome which amino acids to assemble into a protein.
Translation
The amino acids come into the ribosome and are attached to each other by peptide bonds.
Translation
The protein is finished and is ready to be used by the cell.
