Detailed explanation-1: -(3) RNA contains uracil in place of thymine. These chemical differences make it easy for the enzymes in the cell to tell DNA and RNA apart. The roles played by DNA and RNA are similar to the master plans and blueprints used by builders. A master plan has all the information needed to construct a building.
Detailed explanation-2: -“DNA is often referred to as a ‘blueprint for life’. A blueprint is an architect plan, technical drawing or engineering design. Like a blueprint, DNA contains information to guide construction, in this case of a living organism.
Detailed explanation-3: -The master plan is the DNA molecule. The cell uses the molecule to prepare mRNA “blueprints.” The mRNA carries the instructions for protein synthesis from the nucleus to the ribosomes in the cytoplasm, where the proteins are built.
Detailed explanation-4: -Antisense is the non-coding DNA strand of a gene. In a cell, antisense DNA serves as the template for producing messenger RNA (mRNA), which directs the synthesis of a protein.
