replication

replication

5’-3’ structure allows us to replicate DNA by adding new pieces only in a certain direction ensuring accurate copying

transcription

when making RNA from DNA the 5’-3’ arrangement helps in reading the DNA in the right way to create the RNA

translation

for protein creation, following the 5’-3’ order is like reading a recipe correctly to make the protein just as its supposed to be

A & T

adenine and thymine, 2 hydrogen bonds

C & G

cytosine and guanine, 3 hydrogen bonds

structural stability

a&g will be too long

t&c will be too short

structural instability

mismatch in bases

nucleosome structure

8 histones wrapped around by DNA strand that is wrapped around twice and held together by H1 histones
