Diseases associated with alternative splicing include cancer, thalassemia, muscular dystrophy, neurodegenerative diseases, etc. Further reading:... View Article
Yes, exons are present in the mature and processed mRNA, which is transported out of the nucleus for protein synthesis. Further reading: RNA... View Article
Exons are the coding sequence of a gene present in the DNA and the corresponding sequence in RNA. Further reading: RNA Splicing Chromosome... View Article
Introns play a role in the regulation of gene expression. They have a significant role in evolution. Alternative splicing may lead to different... View Article
If introns are not removed by splicing from hnRNA, then mRNA will have an extra junk sequence and will lead to the formation of the wrong protein... View Article
Codon is a trinucleotide sequence, which codes for amino acid and exon is a coding region, which codes for a polypeptide. Further reading:... View Article
DNA methylation generally switches off the gene expression. It represses the transcription of the gene. E.g. during ageing, x-chromosome... View Article
