DNA and RNA

What are nucleotides?

• Nucleotides are the building blocks of proteins, consisting of amino acids.

• Nucleotides are the building blocks of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

• Nucleotides are molecules that store energy in cells, such as ATP.

• Nucleotides are the components of lipids, consisting of fatty acids and glycerol.

What is translation?

• Translation is the process by which ribosomes synthesize proteins using the information encoded in mRNA.

• Translation is the process of converting DNA into RNA.

• Translation is the process of breaking down proteins into amino acids.

• Translation is the process of replicating DNA for cell division.

What is the role of rRNA?

• rRNA is a structural component of ribosomes and plays a role in protein synthesis.

• rRNA is involved in DNA replication.

• rRNA acts as a catalyst in metabolic reactions.

• rRNA is responsible for transporting amino acids to the ribosome.

What is the function of DNA?

• DNA provides energy for cellular processes.

• DNA stores genetic information that codes for the production of proteins.

• DNA helps in the digestion of food.

• DNA is responsible for the movement of muscles.

What is the role of mRNA?

• mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

• mRNA helps in the replication of DNA.

• mRNA is responsible for the transport of oxygen in the blood.

• mRNA acts as a catalyst in metabolic reactions.

What is 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 role of tRNA?

• tRNA transports amino acids to the ribosome during protein synthesis.

• tRNA synthesizes proteins from amino acids.

• tRNA carries genetic information from DNA to the ribosome.

• tRNA helps in the replication of DNA.

What is the base pairing rule in DNA?

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

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

• Adenine (A) pairs with Thymine (T), and Guanine (G) pairs with Uracil (U).

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

What is a gene?

• A segment of RNA that codes for a specific enzyme.

• A segment of DNA that contains the instructions for making a specific protein.

• A type of protein that regulates gene expression.

• A cellular structure that synthesizes proteins.

What is a mutation?

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

• A process that repairs damaged DNA sequences.

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

• A method of cell division that produces identical cells.
