Q

How does double helix form

A

1 complementary bases pair up between nitrogenous bases on 2 polynucleotide chains
Held by hydrogen bonds
Strands are anti parallel forms contestant distance
DNA twists to form very stable double helix

Q

Features of a genetic code

A
  1. Triple code
  2. Non overlapping
  3. Degenerate
  4. Universal
17
Q

Universal

A

Almost all living organisms have the same 5 bases and triplet of DNA base codes and same amino acids

18
Q

Triple code

A

3 nucleotides code for 1 amino acid (3 bases)

19
Q

Non overlapping

A

Code is read so each base is only 1 triplet code

20
Q

Degenerate

A

More triplet codes than amino acids so many amino acids can be coded for by several amino acids

21
Q

What is needed in transcription

A

Gene, RNA polymerase, free RNA nucleotides that are activated
