1 From DNA to Proteins

2 Why is DNA important? genetic information DNA contains __________________ and the instructions for making ________. proteins

3 PROTEINS???? Proteins are the workhorse of the cells. Hemoglobin
Enzyme Hemoglobin Muscle Hair Hormones Antibodies

4 ? How??? Cells use the instructions in DNA to make proteins.
How do cells go from DNA to protein? DNA ? Protein

5 Where in the cell are proteins made?
Proteins are made on __________ ribosomes which are found in the cytoplasm and attached to rough ER. ribosomes

6 DNA contains the instructions for making ________. proteins

7 Where in the cell is DNA stored?
DNA is stored in the _________ in the form of _______________. nucleus chromosomes nucleus chromosomes

8 Never!!! DNA never ever leaves the nucleus!
Does DNA travel outside the nucleus? Never!!! DNA never ever leaves the nucleus!

9 What is a gene? A gene is a section of DNA.

10 TRANSCRIPTION DNA mRNA nucleus ribosome copy of gene mRNA DNA
mRNA exits the nucleus T A A G C C T G A C G C T A T T A T T C G G A C T G C G A T A A DNA gene (section of DNA)

11 TRANSCRIPTION TRANSLATION DNA mRNA mRNA Protein protein nucleus
mRNA attaches to ribosome DNA ribosome T A A G C C T G A C G C T A T T mRNA exits nucleus protein A T T C G G A C T G C G A T A A DNA A protein is made

12 TRANSCRIPTION TRANSLATION DNA mRNA mRNA Protein protein nucleus
mRNA attaches to ribosome DNA ribosome T A A G C C T G A C G C T A T T copy of gene mRNA exits nucleus mRNA mRNA A T T C G G A C T G C G A T A A DNA protein A protein is made gene (section of DNA)

13 The section of DNA (gene) that is copied
is called ______________ or mRNA. messenger RNA mRNA carries instructions for making proteins to the ribosomes where proteins are assembled. DNA T A A G C C T G A C G C T ribosome mRNA A T T C G G A C T G C G A protein DNA gene

14 DNA never leaves the nucleus
DNA never leaves the nucleus. Instead, the cell copies a section of DNA called a gene , sends the “copied gene” or mRNA out of the nucleus and into the cytoplasm where it attaches to a ribosome to direct the assembly of a protein.

15 Protein synthesis involves two steps:
______________: DNA mRNA Transcription Translation mRNA protein
