The answer is chloroplast
Answer:
notochord, a dorsal hollow nerve cord and pharyngeal slits.
The organelle is labeled is nucleus, which means, where the chromosomes and one or more nucleoli are located immersed in the nucleoplasm or also karyolymph.
<h3>What is a nucleus organelle?</h3>
The nucleus, generally the largest eukaryotic cell organelle is the region delimited by membrane, where the chromosomes and one or more nucleoli immersed in the nucleoplasm or also karyolymph are located.
The nucleus of an organelle is composed of the karyotheca, chromatin, nucleoplasm and nucleolus.

Answer: Exons
Explanation:
In eukaryotic cell the primary transcript are very long the contains coding region (exons) and non coding region (introns)
The parts of the gene sequence that are expressed (coding region) in the protein are called exons, because they are expressed, while the parts of the gene sequence that are not expressed in the protein are called introns, because they come in between the exons.
Intron is a portion of a gene that does not code for amino acids. These Intron sequence are cleaved out and exons are spliced (I. E combine together) to form the mature mRNA molecule.
Exons are the mRNA parts that are kept and used to make protein.
