RNA Structure and Function Concepts

The video tutorial explains the structure of RNA and its differences from DNA, focusing on the single-stranded nature of RNA and the presence of ribose sugar. It highlights the base pairing rules, where Uracil replaces Thymine in RNA, and emphasizes the importance of base pairing in DNA replication and mRNA production. The transcription process is detailed, showing how a DNA template strand guides the formation of mRNA, which is crucial for protein synthesis.

What is the main structural difference between RNA and DNA?

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

• RNA is more stable than DNA.

• RNA contains ribose sugar, whereas DNA contains deoxyribose sugar.

• RNA contains Thymine, while DNA contains Uracil.

Which base in RNA pairs with Adenine?

• Thymine

• Cytosine

• Uracil

• Guanine

What is the process called where a section of DNA is unwound to create messenger RNA?

• Replication

• Translation

• Transcription

• Translocation

During transcription, which base in DNA pairs with Uracil in RNA?

• Cytosine

• Thymine

• Guanine

• Adenine

What is the role of messenger RNA in the cell?

• To transport amino acids

• To replicate DNA

• To direct the formation of proteins

• To synthesize lipids

Which of the following is NOT a base found in RNA?

• Guanine

• Thymine

• Adenine

• Uracil
