genetic code

How is DNA condensed into chromosomes

DNA molecules wrapped with histone proteins, this coils into chromatin which helps DNA pack into chromosomes

How many DNA molecules in 1 chromosome

1

What is a gene

Short section of DNA that codes for a specific polypeptide

What s the genetic code

Sequence of bases that codes for amino acids

How many bases in 1 amino acid

3, so 64 possible amino acids but there are only 20

Who confirmed the existence of the triplet code

Crick in 1961

What are the 3 features of the genetic code

Universal, non overlapping and degenerate

What does universal mean

Each dna triplet codes fro the same amino acids in all organisms

What does non overlapping mean

Each base in the dna sequence is only read once

What does degenerate mean

Each amino acid is coded for by multiple triplets
