What are A and G in DNA bases
Purines
What are T and C in DNA bases
pyrimidines
What biological processes involve DNA
Transcription, replication, recombination, repair, regulation
What processes involve RNA
transcription, dna replication, translation, regulation of gene expression, splicing machinery, some viruses
Structures of RNA
hairpins and loop and helix
What is ribosome made of
RNA(majority) and protein
What is nucleotide for
RNA AND DNA
What is AMP
adenosine mono phosphate
What ribose different from deoxy
there is a hydroxyl groupon the sugar
What does adenine and guanine have (purines)
two cyclic structures
What does cytosine, thymine and uracil have (pyrimidine)
one cyclic (N and C alternate)
What is the alternative for thymine in RNA
uracil (one methyl group less)
What is the structure difference in thymine
one methyl and 2 ketone (most complicated)
What is the structure difference in cytosine
a ketone
What is the structure difference of uracil
2 ketone
What is the difference between adenine and guamine
adenine have amide while guanine is amide and ketone
why are there 5’ and 3’ in DNA
they are connect to phosphate in 5’ and 3’
How many bond does AT bond have
2
How bond what GC bond have
3
what can do base pairing
only nucleic acid
What does S stand for in DNA replication
synthesis where the replication occurs
How is DNA synthesised
using DNA polymerases
What do the DNA polymerase I have
smaller
What does DNA polymerase III contain
larger with other proteins, clamp loader and sliding clamp( called dna machinery) to work longer
