RNA stands for Ribonucleic Acid.
There are overall two types of nucleic acid :
● DNA ( Dioxyribonucleic Acid )
It is double stranded means it has two strips in its structure which are joined with each other. it helps in passing characteristics to coming generations.
● Second one is RNA ( Ribonucleic Acid )
It is single stranded means it has only one strip in its structure. it helps in coding.
■ DNA is present in all living cells.
■ RNA is present in viruses.
=> Cells have nucleus.
=> Nucleus has nucleoplasm.
=> Nucleoplasm has two things :
• Nucleolus
• Chromatins
● Nucleolus is rich in substances like RNA and it is the site for protein synthesis.
● The chromatin contains genetic material like DNA.

There are some nucleotides also...and these are :
● Adenine
● Guanine
● Cytocin
● Thymine
In DNA structure...
Adenine combines with thymine and guanine combines with cytocin.
In RNA structures, one nucleotide is different from that of DNA and these are :
● Adenine
● Guanine
● Cytocin
● Uracil
In RNA structure..
Adenine combines with uracil and guanine combines with cytocin.
