The Correct Option is A

Solution and Explanation

The enzyme that cuts DNA from specific places is Restriction endonuclease, often represented by examples such as EcoRI. These enzymes recognize specific DNA sequences and cleave the DNA at or near those recognition sites. This property is widely used in molecular biology techniques such as DNA cloning and genetic engineering to precisely manipulate DNA fragments. So, the correct option is (A): Restriction endonuclease (EcoRI)

DNA - Discovery

Many individuals believe that American biologist - "James Watson" and English physicist - “Francis Crick” discovered DNA in the 1950s. Actually, this is not the case. Preferably, DNA was first recognized in the late 1860s by Swiss chemist - “Friedrich Miescher”.

What actually DNA is?

DNA is self-replicating material that exists in every living organism. In easiest terms, it is a carrier of all genetic information. It contains the instructions required for organisms to develop, grow, survive, and reproduce. It’s one of the longest molecules that contain our genetic “code,” or recipe. This recipe is the initial point for our development, but DNA’s interaction with outside impacts such as our lifestyle, environment, and nutrition ultimately forms human beings.

DNA is a composition of molecules known as nucleotides. Each nucleotide comprises a sugar and phosphate group, also nitrogen bases. These nitrogen bases are further tumbledown into four types, including:

  • Adenine (A)
  • Cytosine (C)
  • Guanine (G)
  • Thymine (T)
