Which of the following terms is used to describe catalytically active RNA molecules?
A
Proteosomes
B
Ribozymes
C
Polymerases
D
Ligases
Verified step by step guidance1
Understand the role of RNA in biological processes: RNA is not only a messenger molecule but can also have catalytic functions.
Identify the term 'catalytically active RNA molecules': This refers to RNA molecules that can catalyze chemical reactions, similar to how enzymes work.
Recognize the term 'Ribozymes': Ribozymes are RNA molecules that have the ability to catalyze specific biochemical reactions, similar to protein enzymes.
Differentiate between the options: Proteosomes are protein complexes, polymerases are enzymes that synthesize DNA or RNA, and ligases are enzymes that join two molecules together.
Conclude that the term 'Ribozymes' is the correct answer for catalytically active RNA molecules, as they are known for their enzymatic activity.
