Answer:
They are disrupted by introns
Explanation:
Open reading frames are defined as the base pair sequence between the start and stop codon in an mRNA. The open reading frames are important from the translation point of view as this is the sequence that can be translated into proteins.
In eukaryotes, the identification of an open reading frame is very difficult as the sequence contains the introns or non-coding sequence which makes it difficult. Therefore the cell must remove these introns from the sequence.
Thus, the selected option is correct.
Open reading frames are the reading frames of the nucleotide sequence. ORFs in eukaryotes are hard to identify as they are disrupted by introns.
What are ORFs and introns?
In the structure of the messenger RNA, the sequence present between the start and the stop codon is called the open reading frames, ORFs. They are crucial for the process of translation.
In a eukaryotic organism, the ORFs are hard to read as the sequence contains introns that are the non-coding sequences and are removed in the splicing process of the post-modification process.
Therefore, ORFs are hard to identify as option B. they are interrupted by the introns.
