Genetic Coding and Protein Synthesis

They are nucleic acids, the same like DNA but contains the sugar ribose.

What are 4 nitrogen bases of RNA?

• Adenine (A)

• Thymine (T)

• Guanine (G)

• Cytosine (C)

• Uracil (U)

Codon is .......

• A sequence of three bases that code for one amino acid

• mRNA codon: C-T-A --> anticodon will be G-A-U

• A sequence of two bases that code for one amino acid

• mRNA codon: C-A --> anticodon will be G-U

A sequence complementary to the corresponding codon in mRNA sequence (mRNA codon: C-T-A --> anticodon will be G-A-U)

Amino acid are .....

• the unit that make up proteins

• the unit that remove proteins

• the unit that change forms into chain
