The DNA is mostly because the hyperchromic effect is very . The fact that there is any hyperchromicity at all means that there may be a amount of intramolecular base-pairing. a. greatb. largec. double-strandedd. smalle. single-stranded

Explanation:

DNA, deoxyribonucleid acid is the genetic material or component of living organisms . It has two two chains that coil around each other to form double helix structure. It is found in the nucleus because it is small and the cell itself is small.DNA have two base pairs and carries genetic information for growth, reproduction, functioning and development.

The DNA is double stranded, the hyperchromic(,its ability to absorb light)effect is small, and there are small amount of molecular base pairing. The hyperchromic effect of DNA is the ability of DNA to absorb light at night temperature. The double stranded DNA is heated at high temperature,and it unwind to single stranded DNA which have the ability to absorb light.
