DNA Versus RNA: Exploring Molecular Structure and Function

The video explores the differences between DNA and RNA, focusing on their form and function in cells. DNA serves as long-term information storage, while RNA is used for active functions. Structural differences, such as DNA's double-stranded form and RNA's single-stranded form, are highlighted. The video also discusses nucleotide components and evolutionary questions about the origin of these molecules. It concludes with acknowledgments and funding information.

What is the primary function of DNA in cells?

• To provide structural support to the cell

• To act as a catalyst in chemical reactions

• To store long-term genetic information

• To transport nutrients across the cell membrane

How does RNA differ from DNA in terms of its role in protein synthesis?

• RNA provides structural support, while DNA does not

• RNA acts as a catalyst, while DNA does not

• RNA directly codes for proteins, while DNA does not

• RNA is used for long-term storage, while DNA is not

What is a key structural difference between DNA and RNA?

• DNA is shorter than RNA

• DNA contains uracil, while RNA contains thymine

• DNA is double-stranded, while RNA is single-stranded

• DNA is single-stranded, while RNA is double-stranded

Why is RNA considered more fragile than DNA?

• RNA is longer than DNA

• RNA lacks a phosphate group

• RNA has a highly reactive OH group

• RNA is double-stranded

What is the sugar component of RNA called?

• Deoxyribose

• Fructose

• Glucose

• Ribose

Which nucleotide base is found in RNA but not in DNA?

• Uracil

• Thymine

• Adenine

• Cytosine

What is the significance of the OH group in RNA?

• It makes RNA more stable

• It allows RNA to be easily broken down

• It prevents RNA from leaving the nucleus

• It makes RNA double-stranded

Why do some viruses use RNA instead of DNA for genetic information?

• RNA is less reactive than DNA

• RNA is more stable than DNA

• RNA is longer than DNA

• RNA can be double-stranded for stability

What evolutionary question is being researched regarding RNA and DNA?

• If RNA was used for both active functions and information storage in early cells

• Whether RNA can replace DNA in modern cells

• Whether DNA can function without RNA

• If DNA was the first genetic material

What is the main focus of the research center mentioned in the video?

• Developing new genetic technologies

• Exploring the medical applications of RNA

• Studying the origin and evolution of life and the universe

• Creating synthetic DNA
