Nucleic Acids Quiz

What is the structure of DNA?

• DNA is a triple-stranded structure made up of lipids

• DNA is a single-stranded structure made up of amino acids

• DNA is a double-stranded structure made up of proteins

• DNA is a double-stranded helix structure made up of nucleotides containing a sugar, a phosphate group, and a nitrogenous base. The nitrogenous bases are adenine (A), thymine (T), guanine (G), and cytosine (C), which pair up in a specific way (A with T and G with C) to form the rungs of the DNA ladder. The sugar and phosphate groups form the sides of the ladder.

What are the subunits of DNA called?

• amino acids

• proteins

• nucleotides

• carbohydrates

What is the function of DNA replication?

• The function of DNA replication is to produce RNA molecules for protein synthesis.

• The function of DNA replication is to produce two identical DNA molecules for cell division and passing on of genetic information.

• The function of DNA replication is to break down DNA molecules for cell division.

• The function of DNA replication is to produce two different DNA molecules for genetic variation.

Which enzyme is responsible for DNA replication?

• DNA polymerase

• Amylase

• Lipase

• RNA polymerase

What is the structure of RNA?

• RNA is a single-stranded molecule composed of nucleotides.

• RNA is a double-stranded molecule composed of nucleotides.

• RNA is a carbohydrate composed of monosaccharides.

• RNA is a protein composed of amino acids.

What is the function of RNA in protein synthesis?

• RNA helps in the replication of DNA.

• RNA is responsible for storing genetic information.

• RNA carries the genetic information from DNA to the ribosomes for protein synthesis.

• RNA is involved in cell division.

What are the three types of RNA?

• mRNA, tRNA, DNA

• mRNA, rRNA, DNA

• mRNA, tRNA, mRNA

• mRNA, tRNA, rRNA

What are nucleotides?

• Nucleotides are the building blocks of DNA and RNA.

• Nucleotides are the basic units of carbohydrates.

• Nucleotides are only found in animal cells.

• Nucleotides are proteins found in the cell nucleus.

What are the components of a nucleotide?

• Nitrogenous base, five-carbon sugar, and sulfur group.

• Nitrogenous base, six-carbon sugar, and phosphate group.

• Nitrogenous base, five-carbon sugar, and phosphate group.

• Carbon base, five-nitrogen sugar, and phosphate group.

What is the role of nucleotides in DNA and RNA?

• Nucleotides are responsible for energy production in cells

• Nucleotides are the building blocks of DNA and RNA, responsible for carrying genetic information and determining the sequence of amino acids in proteins.

• Nucleotides are involved in the synthesis of lipids

• Nucleotides are used for cell division
