The protein complex responsible for removing intron-encoded rna sequences from primary transcripts in eukaryotes is called the

spliceosome is a correct answer.

Explanation:

spliceosome: protein complex responsible for removing intron-encoded RNA sequences from primary transcripts in eukaryotes.

spliceosome is a molecular machine ribonucleoprotein ,that is present inside the nucleus of the eukaryotic.spliceosome removes the noncoding region which is called as intron from the pre-mRNA transcript and form a mature mRNAs which is then translated into protein.Introns are present in the eukaryotic genes, introns are removed by the splicesome and the process is called splicing.
