Verified step by step guidance

Understand the role of RNA molecules in the cell, particularly those involved in processing pre-mRNA.

Recall that mRNA (messenger RNA) carries the genetic code from DNA to the ribosome for protein synthesis.

Recognize that rRNA (ribosomal RNA) is a structural and catalytic component of ribosomes.

Know that tRNA (transfer RNA) brings amino acids to the ribosome during translation.

Identify that small nuclear RNA (snRNA) molecules are specifically involved in the splicing of introns from pre-mRNA, assisting the spliceosome in removing non-coding sequences.
