Which of the following is true about nucleic acids? I. Nucleic acids always consist of a five-carbon sugar, a nitrogenous base,
and one or more phosphate groups. II. Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids. III. Nucleic acids are usually insoluble in water and are used for long term energy storage. IV. Glucose, cellulose, and starch are examples of nucleic acids found in most cells.
II. Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids.
Explanation:
Nucleic acids are essential biomolecules for all living organisms. They carry genetic information and decode the production of proteins, necessary for the cell to reproduce. While they are formed of five-carbon sugars, a nitrogenous base they only have one phosphate group. They do not store energy. Also, glucose, cellulose and starch are not nucleic acids, they are carbohydrates.
Hi! <span>I. Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups. </span> <span>II.
Both DNA, which stores genetic information and encodes protein
sequences, and RNA, which is involved in the direct production of
proteins, are nucleic acids.
A silent point mutation may be an effect of a base-pair substitution (substitution of one base pair with another in DNA). However, silent point mutations are a special case where no amino acids are affected. As a result, since the monomers of proteins are amino acids, there is no change to the sequence of a protein.
