In split genes, the coding sequences are called:
Correct answer: A. Exons
- A. Exons
- B. Cistrons
- C. Introns
- D. Operons
Explanation
Split genes are those genes that consist of a continuous sequence of nucleotides (coding sequences) interrupted by intervening sequences. Most eukaryotic genes are split as are genes of some animal viruses. The continuous coding sequences are called exons, and the intervening noncoding sequences are called introns. These introns are not represented in mRNA transcribed from the gene and are not utilised for the synthesis of proteins.

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.
