WebAug 6, 2024 · In general, introns are much longer than exons; they can make up as much as 90% of a gene and can be over 10,000 … WebCancer can be caused by many different mutations in cells. Some of these mutations are the result of incorrect intron excision by splicing enzymes. Introns are extra nucleotide sequences that must be removed from precursor RNA to get the correct template for protein translation. Intron excision is important in the nucleus of animal and plant cells, as well … WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. chiropractic stroke
