introns only exons only both introns and exons
answer bank
removed from initial mrna strand prior to translation present in the dna used as the template for transcription code for a protein
present in eukaryotic genomes part of the final mrna strand generally absent from bacterial genomes

Explanation:

• Introns only: Introns are removed from the initial mRNA strand prior to translation.
• Exons only: Exons are part of the final mRNA strand and code for a protein.
• Both introns and exons: Both are present in the DNA used as the template for transcription, present in eukaryotic genomes, and generally absent from bacterial genomes.

Answer:

• Introns only: removed from initial mRNA strand prior to translation
• Exons only: part of the final mRNA strand, code for a protein
• Both introns and exons: present in the DNA used as the template for transcription, present in eukaryotic genomes, generally absent from bacterial genomes
