Proteins and Nucleic Acids

What are the two types of nucleic acids?

• DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid)

• Protein and Lipid

• Carbohydrate and Fiber

• Glucose and Fructose

What is the function of enzymes?

• Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.

• Enzymes are carbohydrates that provide energy to cells.

• Enzymes are lipids that store genetic information.

• Enzymes are minerals that help in muscle contraction.

What sugar does DNA contain?

• Ribose

• Deoxyribose

• Glucose

• Fructose

What is the primary function of proteins in the body?

• To serve as structural building blocks, enzymes, and transport molecules.

• To provide energy for cellular processes.

• To store genetic information.

• To act as a source of vitamins and minerals.

What is the significance of the sequence of nucleotides in DNA?

• It determines the color of an organism's eyes.

• It encodes genetic information that determines the traits of an organism.

• It controls the speed of cellular processes.

• It is responsible for the production of energy in cells.

How do proteins contribute to cell transport?

• Proteins can function as channels or carriers to facilitate the movement of substances across cell membranes.

• Proteins are primarily involved in energy production within the cell.

• Proteins serve as structural components of the cell membrane only.

• Proteins are responsible for the synthesis of lipids in the cell.

What is the difference between purines and pyrimidines?

• Purines are single-ringed nitrogenous bases, while pyrimidines are double-ringed.

• Purines include cytosine and thymine, while pyrimidines include adenine and guanine.

• Purines are double-ringed nitrogenous bases (adenine and guanine), while pyrimidines are single-ringed (cytosine, thymine, and uracil).

• Purines and pyrimidines are both double-ringed nitrogenous bases.

What is the role of RNA in protein synthesis?

• RNA acts as a messenger carrying instructions from DNA for controlling the synthesis of proteins.

• RNA is responsible for the replication of DNA.

• RNA serves as a structural component of ribosomes only.

• RNA is involved in the degradation of proteins.

DNA and RNA are examples of what?

• Proteins

• Carbohydrates

• Nucleic acids

• Lipids

What are the components of a nucleotide?

• Nitrogen base, phosphate group, and sugar.

• Amino acids, fatty acids, and glycerol.

• Glucose, ribose, and deoxyribose.

• Cholesterol, triglycerides, and phospholipids.
