RNA Translation and Transcription. DNA replication starts with an enzyme called Helicase , The Helicase separates the Hydrogen bonds that are in between the two complementary bases. This acts like a zipper. DNA REPLICATION.

Rna translation and transcription

RNA Translation and Transcription


Dna replication

DNA REPLICATION


  • The DNA polymerase binds to a single strain of the old (parent) DNA, and uses it as a template to makes a new chain.

  • The result is a new strain that is half old half new.


Replication means exact copies of DNACopies are used for new cells for growth and repairThe sugar in DNA is deoxyribose.


  • Ribonucleic acid - Stores and transfers genetic information essential for making proteins.

  • Sugar phosphate backbone (sugar = ribose)

  • One stranded

  • Four bases

    • Adenine, Guanine, Uracil, Cytosine

Translation


Mutations

  • Change in DNA bases of three bases at a time. It will then code for an amino acid, which will combine to make a protein

  • Can be random or caused by the environment (ex: radiation)

  • Can make a significant change or very little change to organism

  • Sometimes is bad, sometimes can be good

Mutations


Front and front gators
Front and Front Gators of three bases at a time. It will then code for an amino acid, which will combine to make a protein


Two faced kitten
Two faced kitten of three bases at a time. It will then code for an amino acid, which will combine to make a protein


Lots of frog legs
Lots of Frog Legs of three bases at a time. It will then code for an amino acid, which will combine to make a protein
