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.
Common characteristics of modern bears include large bodies with stocky legs, long snouts, small rounded ears, shaggy hair, plantigrade paws with five nonretractile claws, and short tails.
