Question

which of the following is true about rna?
a rna is involved in the first part of the central dogma.
b rna is created in the cytoplasm.
c rna carries the genetic information from out of the nucleus to ribosomes in the cytoplasm.
d rna solely determines the structure and function of cells.

Explanation:

• Option a: The first part of the central dogma is DNA replication, not directly involving RNA.
• Option b: RNA is created in the nucleus through transcription.
• Option c: mRNA (a type of RNA) carries genetic information from the nucleus (where DNA is) to ribosomes in the cytoplasm for protein synthesis.
• Option d: DNA also plays a crucial role in determining cell structure and function, not just RNA.

Answer:

C. RNA carries the genetic information from out of the nucleus to ribosomes in the cytoplasm.
