Which of the following is an important exception to the central dogma of molecular biology? a) Proteins are responsible for most
iogann1982 [59]

Answer:

b: many genes code for RNAs that function directly in the cell

Explanation:

<em>The central dogma</em> theory describes the basic framework for gene expression in living organisms. Genetic information from DNA is encoded or transcribed as RNA which then becomes translated as proteins.

The processes that take place for gene to be successfully expressed are;

  • Replication
  • Transcription
  • Translation

<em>Replication</em> is a process whereby DNA makes a copy of itself to be distributed in daughter cells during cell division.

<em>Transcription</em> is the process whereby genetic information in DNA is encoded as RNAs. The RNAs are short-lived as they are quickly utilized in protein synthesis or <em>translation </em>process.

Hence, the RNAs do not function directly in the cells but mere intermediaries in the synthesis of proteins.

<em>The correct option is b.</em>
