Hii.. guys... full form of DNA AND RNA...
Difference between them...
Answers
Answer:
FULL FORM OF DNA IS DEOXYRIBONUCLEIC ACID .AND RIBONUCLEIC ACID .
Explanation:
.
DNA
RNA
1. DNA stands for Deoxyribonucleic Acid. The sugar portion of DNA is 2-Deoxyribose. RNA stands for Ribonucleic Acid. The sugar portion of RNA is Ribose.
2. The helix geometry of DNA is of B-Form (A or Z also present). The helix geometry of RNA is of A-Form.
3. DNA is a double-stranded molecule consisting of a long chain of nucleotides. RNA usually is a single-strand helix consisting of shorter chains of nucleotides.
4. The bases present in DNA are adenine, guanine, cytosine and thymine. The bases present in RNA are adenine, guanine, cytosine and uracil.
5. DNA is self-replicating. RNA is synthesized from DNA on an as-needed basis.
6. Base Pairing :AT (adenine-thymine)GC (guanine-cytosine). Base Pairing :AU (adenine-uracil)GC (guanine-cytosine).
7. Purine and Pyrimidine bases are equal in number. There is no proportionality in between the number of Purine and Pyrimidine bases.
8. DNA is susceptible to UV damage. Compared with DNA, RNA is relatively resistant to UV damage.
9. Hydrogen bonds are formed between complementary nitrogen bases of the opposite strands (A-T, C-G). Base pairing through hydrogen bonds, occurs in the coiled parts.
10. DNA is found in the nucleus of a cell and in mitochondria. Depending on the type of RNA, this molecule is found in a cell’s nucleus, its cytoplasm, and its ribosome.
Explanation:
Structurally , DNA and RNA are the polymers of nucleotides. Certain nucleotides( aggregation of a pentose sugar, a phosphate group and nitrogenous bases purines and pyrimidines) code for a particular genetic information. DNA is the acronym for Deoxyribonucleic acid and RNA for ribonucleic acid
