Kornberg, in his experiments to demonstrate the function of DNA polymerase I, sought to show that DNA Pol 1 was capable of replicating biologically active DNA. What is the definition of biologically active DNA in this context?

Explanation:

Kornberg performed the experiment to identify the molecules which could be able to replicate the DNA. He used a bacterial strain and bacteriophage which could infect the bacteria by incorporating its DNA.

He was able to detect an enzyme which cold assemble all the molecules to form a new DNA strand and named the enzyme as DNA polymerase.

This DNA polymerase can replicate biologically active DNA in which biologically active means that a biological active progeny DNA of phage was which is very accurate and is viable is produced by the bacteria using the enzyme DNA polymerase.

the answer is d.) homologous; have mammary glands

not too sure but maybe in the hot springs.
