RNA Structure and Function: Key Differences from DNA

The video tutorial explains the structure and function of ribonucleic acid (RNA) in comparison to deoxyribonucleic acid (DNA). It highlights the structural similarities and differences, such as RNA being single-stranded and having ribose sugar and uracil instead of thymine. The tutorial also covers RNA's role in cellular functions, including coding, decoding, regulating, and expressing genes, with a focus on different types of RNA like mRNA, tRNA, and rRNA.

What is a common structural feature shared by both RNA and DNA?

• Double-stranded helix

• Sugar-phosphate backbone

• Presence of uracil

• Ribose sugar

Which of the following is a key structural difference between RNA and DNA?

• RNA contains thymine

• RNA has a ribose sugar

• RNA is double-stranded

• RNA is more stable than DNA

What nitrogen base does RNA have that DNA does not?

• Guanine

• Adenine

• Cytosine

• Uracil

In RNA, which base pairs with adenine?

• Guanine

• Uracil

• Cytosine

• Thymine

What is the significance of the 3' and 5' ends in RNA?

• They are unique to DNA

• They are involved in the addition of nucleotides

• They indicate the RNA's length

• They determine the RNA's stability

Which type of RNA is responsible for carrying genetic information from DNA to the ribosome?

• snRNA

• mRNA

• rRNA

• tRNA
