If two purines existed that were complementary at their Hint

If two purines existed that were complementary at their H-interaction positions, they would fit well in a DMA helix Choose... All base PAIRS (GC, AT, CG, and TA). when considered as units, form very similar structures Choose... The awesome properties of the bases are achieved by violating the laws of chemistry and using radioactive atoms Choose... The bases are loose, floppy structures, which allows them to wiggle and achieve better fits with their partners Choose...

Solution

1. ANS: No.

Explanation:

According to the Watson and Crick model of DNA, between A & T there are two hydrogen bonds and G &C three hydrogen bonds are present. So the G purine had one additional hydrogen interaction position.

2. ANS: Yes.

Explanation:

The first rule of Chargraff states purines are always equal to pyrimidine. It explains the purines always pairs with a pyrimidine. So GC, AT, CG and TA are considered as a units of DNA molecule.

3. ANS: No.

Explanation:

The violation of basic chemical structures of nucleic acid (in DNA or RNA) molecules by using radiations can leads to mutations in nucleic acids (in DNA or RNA). It is negatively effects the organism, No awesome properties are not achieved.

4. ANS: No.

Explanation:

The nucleic acids (in DNA or RNA) never present in floppy structure. The 3 D structure is never possible in floppy structure.
