RNA and Transcription

Question 1

What is the main difference between RNA and DNA regarding nitrogen bases?

Answer 1

In RNA, Thymine is replaced by Uracil.

RNA is half of the DNA molecule.

Question 2

What mnemonic can help remember RNA base pairing?

Answer 2

All Ugly Guys Cry.

This indicates that Adenine bonds with Uracil and Guanine bonds with Cytosine.

Question 3

What is the primary function of DNA?

Answer 3

Stores the information on how to make a new organism.

DNA serves as the blueprints for organism development.

Question 4

What role does RNA play in protein synthesis?

Answer 4

Carries out the work of building proteins.

RNA acts as the contractor in the process of protein synthesis.

Question 5

List the three types of RNA.

Answer 5

• messenger (mRNA)
• ribosomal (rRNA)
• transfer (tRNA)

Each type of RNA has a specific role in the process of protein synthesis.

Question 6

What is transcription?

Answer 6

The process by which an RNA sequence is created from a DNA template.

During transcription, A in DNA pairs with U in RNA since there is no T in RNA.

Question 7

Fill in the blank: In RNA, the base _______ pairs with Adenine in DNA.

Answer 7

Uracil

Question 8

True or False: RNA is a complete copy of the DNA molecule.

Answer 8

False

RNA is half of the DNA molecule.
