Removal of introns and joining of exons in a defined order during transcription is called:
Correct answer: D. Splicing
- A. Looping
- B. Inducing
- C. Slicing
- D. Splicing
Explanation
Introns, which mainly occur in eukaryotes, are transcribed into messenger RNA (mRNA) but are then removed from the transcript before translation. In some cases, the removal of introns is an autocatalytic process (self-splicing) in which the RNA itself acts as an enzyme.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
