Remember….Nucleic Acid – one of the BIG FOURDNA – Deoxyribonucleic Acid
Directions for building proteinsNucleotides are building blocks

The big picture…Cell needs a protein – a gene in DNA is the directions, must copy the directions then build the protein.

2: Describe the 3 types of RNA and their job.1. Messenger RNA (mRNA)- “copy” of DNA,
holds the instructions of how to build the protein
Made in the nucleusLeaves nucleus to deliver instructions

2: Describe the 3 types of RNA and their job.2. Ribosomal RNA (rRNA) – attaches to
mRNA and reads it. Then places amino acids in place.
3. Transfer RNA (tRNA) – delivers the amino acids to the rRNA.

3: Explain the process of transcription.IN the NUCLEUS:
mRNA is built from the DNAMuch like replication, base pairing happensA-U, G-C
Only have to make 1 strand
Example of Transcription in the nucleusDNA – T A C G T A T A G G C
mRNA -
DNA T A G C
mRNA A U C G

3: Explain the process of transcription.PROCESSINGBefore mRNA leaves the nucleus noncoding regions are edited out.Introns – (intervening regions) parts of DNA/mRNA that do not code for the protein Get REMOVED
Exons –( expressed regions) parts of DNA /mRNA that MUST be used to make a protein
DNA - T A C G G T C A A T CmRNA - this final product leaves the nucleus

4. Describe the process of translation.Building the Protein
1.mRNA comes out to cytoplasm
2.rRNA (ribosome) binds the mRNA at start codon1. Reads the mRNA in CODONS – three nucleotides
at a time
3.tRNA brings amino acids in 1. its anticodon must be complementary to the
mRNAs codon
4.Amino acids are attached to the building strand of a.a. also known as a polypeptide chain
5.Translation stops at a STOP codonhttp://www.youtube.com/watch?v=983lhh20rGY

5 – Use the genetic code to build an amino acid chain
Start Codon – AUGMUST find AUG to start!!!
Stop Codons – UGA, UAA, UAGMUST stop at STOP codon!!!
