Nucleic Acids

What are nucleotides?

• Nucleotides are the building blocks of DNA and RNA.

• Nucleotides are proteins that help in cell division.

• Nucleotides are lipids that store energy in cells.

• Nucleotides are carbohydrates that provide structural support.

What is a mutation?

• A change in the DNA sequence that can lead to changes in protein function.

• A process that repairs damaged DNA sequences.

• A type of genetic engineering used to create new species.

• A method of cloning organisms for research purposes.

Which nucleotide would Cytosine (C) bond with?

• Adenine (A)

• Thymine (T)

• Guanine (G)

What is the process of transcription?

• Transcription is the process of copying a segment of DNA into RNA.

• Transcription is the process of translating RNA into proteins.

• Transcription is the process of replicating DNA into DNA.

• Transcription is the process of synthesizing lipids from carbohydrates.

What is the structure of DNA?

• DNA is a single strand of amino acids.

• DNA is a double helix composed of two strands of nucleotides.

• DNA is a triple helix made of ribonucleic acids.

• DNA is a linear chain of sugars and phosphates.

What is the role of ribosomal RNA (rRNA)?

• It transports amino acids to the ribosome.

• It forms the core of ribosome's structure and catalyzes protein synthesis.

• It synthesizes DNA during cell division.

• It acts as a signal for protein degradation.

What is the function of messenger RNA (mRNA)?

• To carry the genetic information from DNA to the ribosomes for protein synthesis.

• To replicate DNA during cell division.

• To transport amino acids to the ribosomes.

• To synthesize lipids in the cell.

ATP is a special type of _______ that is the energy currency of the cell.

• nucleotide

• amino acid

• carbohydrate

• lipid

What is the significance of the genetic code?

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

• It is the set of rules by which information encoded in genetic material is translated into proteins.

• It controls the speed of cellular processes.

• It is responsible for the structure of carbohydrates.

What are the four nitrogenous bases in DNA?

• Adenine (A), Thymine (T), Cytosine (C), and Guanine (G)

• Adenine (A), Uracil (U), Cytosine (C), and Guanine (G)

• Adenine (A), Thymine (T), Cytosine (C), and Uracil (U)

• Cytosine (C), Thymine (T), Guanine (G), and Uracil (U)
