Answer:
each new DNA double helix consists of one old DNA strand and one new DNA strand
Explanation:
DNA replication is a semi-conservative process which means a new DNA duplex contains one old DNA strand and one new DNA strand because each DNA strand act as a template strand over which a complementary new DNA strand is made.
So after the completion of DNA replication, each new DNA double helix consists of an old strand of DNA and a new DNA strand. After the replication, only one strand is used for transcription. In RNA formation uracil comes in place of thymine.
