Purine & Pyrimidine Structures || Easy way to memorize

[Music]

hello guys in today's lecture we are

going to talk about how to memorize easy

way into purine and pyrimidine

structures so let's start so we all know

purine and pyrimidine are new nitrogen

bases which are mostly used in the

structure of dna

so

purine it contain nine member

it drop cyclic ring

so this is the basic structure of purine

give the number one

two

three

four

five six

seven

eight

and nine

now place nitrogen at one

three

seven and

nine position

so it form like this

so this is the basic structure of

purines

so now urine base are two types adenine

and one

so for adenine

place

one amino group

at six position so it from a dna

and for one

place

two position eight observed amino group

so it look like that

second position amino group

and at sixth position

so it forms one in so these two ways are

pure invasive pyrimidine ring contain

six member aromatic ring

so in this ring place nitrogen at one

and third position

so this is the basic structure of

pyrimidine so pyrimidine contain mostly

three types of bases

thymine

cytosine

and

uracil

so for making uracil

place

second position and sixth position

observed

so this is the basic structure of

viewership

and for timing

same as eurasim but place

thymine

and for cytosine

cytosine is bind with one and we all

know that so it is a reversible

structure of one

so in one end we all know

at second position amino group and sixth

position where oxo grouper plays so in

this there's reversible so at second

position

group is there and at 6 position

m in a rupees

so this is the easy way to memorize

urine and pyrimidine structure rather

than grasping so guys that's for all for

today and if you want to know or learn

anything from me so just mention below

the comment section thank you
