Explanation / Answer

DNA is double stranded and contains Adenine, Guanine, Cytosine and Thymine as nitrogenous bases. On the other hand RNA is single stranded and consists of same nitrogenous bases as that of DNA like Adenine, Guanine, Cytosine and but there is Uracil instead of Thymine.

1. It is double stranded

2. It consists of Thymine along with Adenine and Guanine Cytosine

3. It is not further divided functionally

4. DNA is present in the nucleus

5. DNA has long chain of nucleotides

6. Deoxysugar in the DNA is less reactive

7. DNA has small grooves to prevent the attack of enzymes

8. The helix geometry of DNA is in B form and stable

1. It is single stranded

2. It consists of Thymine along with Adenine DNA should stay in the nucleus while RNA can leave the nucleus

3. It is further divided into Transfer RNA, Messenger RNA and Ribosomal RNA (tRNA, mRNA and rRNA)

4. rRNA is associated with the ribososmes, tRNA is associated with the ribosomes, cytoplasm and mRNA is temporarily created in the nucleus and reaches the ribosome

5. RNA has shorter chain of nucleotides

6. Ribose sugars in the RNA is more reactive due to the carbon hydroxyl bonds

7. RNA has large grooves which is more prone to attack by enzymes

8. The helix geometry of RNA is in A form which can be broken down and reused

Since DNA contains all the essential genetic information which is important for the existence and survival of an organism it should stay intact in the nucleus and is protected within the nuclear membrane. But in order for protein synthesis to take place according to the genes expressed, DNA is turned into RNA (genetic code travels in the form of mRNA) which can easily cross through the pores in the nuclear membrane and carry out the process of translation.

RNA being short chained, less nucleotides its ability to react and recycle they can easily move in and out of the nuclear membrane to carry out the protein synthesis
