Webeach new DNA double helix consists of one old DNA strand and one new DNA strand. The first step in the replication of DNA is catalyzed by _____. helicase. The action of … WebEach strand serves as a template for the DNA polymerase to catalyze the addition of the correct base during synthesis of a new complementary strand. As the strands are antiparallel with opposing polarity and since DNA polymerases can only synthesize DNA in the 5′ to 3′ direction, only one strand is continuously synthesized.
Web16. mar 2024. · 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 … Web19. apr 2024. · Explanation: DNA replication is semi-conservative, so when you get a "new strand" of DNA, it is made of an old single strand and a new single strand.
