Answer :
Answer:
d. intron splice sites
Explanation:
- Splice sites are a characteristic of eukaryotic genomes. Eukaryotes have exons i.e. coding regions and introns i.e. non-coding or regulatory regions.
- During post-transcriptional modification, introns from the transcribed pre-mRNA are removed by a process known as splicing. With the introns removed, the exons are combined to produce a mature translatable mRNA.
- Prokaryotic genomes are only composed of exons. They do not possess introns.
- Prokaryotic genes are transcribed and translated simultaneously without the need of post transcriptional modifications.
