How Well Do You Know DNA and Proteins?

What are the building blocks of life that make up DNA and proteins?

Choose the correct answer:

A. Carbohydrates

B. Nucleic acid and protein

C. Lipids

D. Vitamins

Answer:

B. Nucleic acid and protein

DNA and proteins are essential components of living organisms. DNA, or deoxyribonucleic acid, carries genetic information and hereditary traits, while proteins are involved in various functions such as structure, regulation, and signaling within cells.

DNA is made up of nucleic acid and protein. Nucleic acids are polymers made up of nucleotide monomers, which consist of a nitrogenous base, a pentose sugar, and a phosphate group. Proteins are polymers made up of amino acid monomers linked together by peptide bonds.

The interaction between DNA and proteins is crucial for the proper functioning of cells. Proteins can bind to specific regions of DNA to regulate gene expression, and DNA serves as a template for the synthesis of proteins through the process of transcription and translation.
