Document Summary

Genes of higher eukaryote are usually composed of exons that are coding, expressed regions, and introns, non-coding regions. A spliceosome removes the introns and joins the exons in a process called rna splicing. Humans have about 21 000 genes that encode for 100 000 proteins because of alternative splicing. Non-protein-coding rna (ncrna) perform many essential roles. Rna copy of the gene must be synthesized in a process called transcription: first step is to copy, or transcribe, the information into a strand of rna, using. Dna as a template: converted into an amino acid chain (protein) by translation. In eukaryotes, these take place in two different places, the former being in the nucleus and the latter being in the cytoplasm: before going into the cytoplasm, unde(cid:396)goes (cid:396)e(cid:373)o(cid:448)al of i(cid:374)t(cid:396)o(cid:374)s, (cid:1009)" (cid:272)ap a(cid:374)d pol(cid:455)-a tail addition.
