The process in which mutations are removed
Webb8 juni 2024 · Introns are removed and degraded while the pre-mRNA is still in the nucleus. Splicing occurs by a sequence-specific mechanism that ensures introns will be removed and exons rejoined with the accuracy and precision of a single nucleotide.

WebbIn splicing, some sections of the RNA transcript (introns) are removed, and the remaining sections (exons) are stuck back together. Some genes can be alternatively spliced , leading to the production of different mature … WebbThere are different types of genetic mutations that can occur in a cell. Point mutations involve the replacement of one base with another.Frame-shift mutations occur when a base is added or removed from the sequence. Non-sense mutations create a stop codon, which can prevent the protein from being produced entirely, while missense mutations ...
