Protein Synthesis DNA codes for Proteins Proteins become enzymes, muscle filament, and walls of blood vessels

Proteins Refresher Building blocks: amino acids Their shape determines their function Proteins are polymers of amino acids *Polymers are long chains

RNA: Ribonucleic Acid It is a nucleic acid just like DNA It is single stranded, it’s sugar is Ribose, and has 4 Nitrogenous bases.

4 Nitrogenous Bases Adenine Uracil (NOT THYMINE) Guanine Cytosine

Practice Converting DNA to RNA DNA: A-T-G-T-T-A-A-A-A-G-C RNA: U-A-C-A-A-U-U-U-U-C-G RNA still follows the complementary base pairing, BUT SUBSTITUTES U FOR T

3 Types of RNA mRNA (Messenger RNA) rRNA (Ribosomal RNA) tRNA (Transfer RNA)

1. mRNA: Messenger RNA JOB: Carries a copy of DNA from the nucleus to the ribosome

2. rRNA: Ribosomal RNA JOB: Clamps onto mRNA and uses its information to make amino acids

3. tRNA: TRANSFER RNA Job: transfers amino acids to ribosome

m in mRNA is for Messenger t in tRNA is for Transfer

Ribosome

Protein Synthesis means to

To Make Proteins

DNA codes for

Proteins

What are the building blocks of Proteins?

Amino Acids

Change the protein you change the_____________

Proteins Refresher Building blocks: amino acids Their shape determines their function Proteins are polymers of amino acids *Polymers are long chains

What are polymers?

What are the things about RNA?

It is single stranded, it’s sugar is Ribose, and has 4 Nitrogenous bases.

What are RNA’s nitrogenous bases?

4 Nitrogenous Bases Adenine Uracil (NOT THYMINE) Guanine Cytosine

Convert to RNA DNA: A-T-G-T-T-A-A-A-A-G-C

Practice Converting DNA to RNA RNA: U-A-C-A-A-U-U-U-U-C-G RNA still follows the complementary base pairing, BUT SUBSTITUTES U FOR T

What are the 3 types of RNA?

3 Types of RNA mRNA (Messenger RNA) rRNA (Ribosomal RNA) tRNA (Transfer RNA)

What is mRNA’s Job?

1. mRNA: Messenger RNA JOB: Carries a copy of DNA from the nucleus to the ribosome

What is tRNA’s job?

3. tRNA: TRANSFER RNA Job: transfers amino acids to ribosome

What is rRNA’s job?

2. rRNA: Ribosomal RNA JOB: Clamps onto mRNA and uses its information to make amino acids
