Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
DNA replication is considered ____ because it uses the old strands as templates?
A
RNA
B
wasteful
C
semiconservative
D
aggressive
Explanation: 

Detailed explanation-1: -DNA replication is semiconservative, meaning that each strand in the DNA double helix acts as a template for the synthesis of a new, complementary strand. This process takes us from one starting molecule to two “daughter” molecules, with each newly formed double helix containing one new and one old strand.

Detailed explanation-2: -Semiconservative replication is so named because one of the strands of DNA in each of the two copies of DNA is ancient and conserved while the other is newly produced at the moment of replication.

Detailed explanation-3: -In DNA replication, each strand of the original DNA serves as a template for the synthesis of a complementary strand. DNA polymerase is the primary enzyme needed for replication. In transcription, a segment of DNA serves as a template for the synthesis of an RNA sequence.
