If and isolated strain of DNA is kept at \(82-90^{\circ} \mathrm{C}\) then
1 it changes into RNA
2 it breaks into two fragments
3 it breaks into many fragments
4 it uncoils and the two strands separate
Explanation:
When DNA is heated to a temperature range of \(82-90^{\circ} \mathrm{C}\), it undergoes a process called denaturation. During denaturation, the hydrogen bonds between the complementary base pairs in the double stranded DNA molecule break, causing the two strands to separate or "uncoil".

Chromosome is made up of
1 DNA and pectin
2 RNA and DNA
3 DNA and histone
4 only histone
Explanation:
Chromosome is made up of DNA and histone. The combination of DNA and proteins is called chromosome. The protein in the chromosome is called histone, which is packed in a linear fashion.

Har Govind Khorana was awarded the Nobel Prize for
1 gene synthesis
2 discovery of bacteria
3 genetic code
4 protein synthesis
Explanation:
Har Govind Khorana was awarded the Nobel Prize for gene synthesis. Har Govind Khorana developed a chemical method that was used in synthesizing RNA molecules with defined combinations of bases. - Genetic code :- The genetic code is universal. The genetic code is the set of biochemical rule governing how genetic information encoded in nucleic acid is converted into polypeptides (proteins).

Unit of nucleic acid is :
1 nucleotide
2 nucleoside
3 nucleic acid
4 all of the these
Explanation:
Unit of nucleic acid is nucleotide. Nucleotides consists of a sugar group, a phosphate group and a nitrogen base. - Nucleic acid :- Nucleic acids are key molecules that contain genetic information and participating in protein synthesis.
