Question

Compare the two new strands of dna are they the same or different? why?

Answer 1

The two new strands are different from each other ,both of them have only one strand from the original DNA and the other strand is complementary . eg if a strand has the following base pairs .. AACCGGT ( consider this as the strands)
                                                           TTGGCCA
now they are going to be seperated AACCGGT     TTGGCCA
                                                         TTGGCCT      AACCGGT
as u can see the two NEW strands formed are similar but NOT IDENTICAL to each other .

Answer 2

Answer:

Not Identical but complementary

Explanation:

The two strands of DNA are not identical or exactly the same. However, the base units of both the DNA strands are same. Generally the base pairs or codon of the two DNA strands are complementary to each other. As per the Chargaff rule  

A joins with T  

and C joins with G

Let us suppose the structure of base DNA strand is ACC TGG ATA CCG

Then the structure of other base strand is TGG ACC TAT GGC

Hence, the two new strands of DNA are different, opposite or complementary  to each other.
