DNA and RNA Review

What is the full form of DNA?

• Deoxyribonucleic Amine

• Deoxyribonucleic Alloy

• Deoxyribonucleic Acid

What are the building blocks of DNA?

• Proteins

• Carbohydrates

• Nucleotides

• Lipids

Describe the double helix structure of DNA.

• The double helix structure of DNA is a triangular form.

• The double helix structure of DNA is a single-stranded linear shape.

• The double helix structure of DNA consists of two strands that are twisted around each other in a spiral shape.

• The double helix structure of DNA is a square-shaped configuration.

What is the function of RNA in the cell?

• RNA regulates cell metabolism

• RNA is responsible for cell division

• RNA stores energy for the cell

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

How does RNA differ from DNA in terms of structure?

• RNA is single-stranded, contains ribose sugar, and uracil instead of thymine.

• RNA is single-stranded, contains deoxyribose sugar, and thymine instead of uracil.

• DNA is single-stranded, contains ribose sugar, and uracil instead of thymine.

• RNA is double-stranded, contains deoxyribose sugar, and thymine instead of uracil.

What are the three types of RNA?

• mRNA, DNA, rRNA

• tRNA, mRNA, sRNA

• rRNA, tRNA, mRNA

• mRNA, tRNA, rRNA

Explain the process of transcription in molecular biology.

• Transcription is the process of converting RNA into DNA.

• Transcription is the process of synthesizing proteins from amino acids.

• Transcription is the process of cell division.

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

What is the role of mRNA in protein synthesis?

• mRNA acts as a messenger to transfer genetic information from DNA to the ribosomes for protein synthesis.

• mRNA functions as a storage unit for excess genetic material.

• mRNA is responsible for breaking down proteins into amino acids.

• mRNA serves as a structural component in the ribosomes during protein synthesis.
