WebGenetic disorders can be: Chromosomal: This type affects the structures that hold your genes/DNA within each cell (chromosomes). With these conditions, people are missing or have duplicated chromosome material. Complex (multifactorial): These disorders stem from a combination of gene mutations and other factors. WebIf the DNA can be repaired, p53 activates other genes to fix the damage. If the DNA cannot be repaired, this protein prevents the cell from dividing and signals it to undergo apoptosis. By stopping cells with mutated or damaged DNA from dividing, p53 helps prevent the development of tumors.
WebFeb 4, 2024 · A point mutation—the change of a single nitrogen base in a DNA sequence —is usually the least harmful type of DNA mutation. Codons are a sequence of three nitrogen bases in a row that are "read" by messenger RNA during transcription. That messenger RNA codon is then translated into an amino acid that goes on to make a protein that will be ... WebMar 5, 2024 · A point mutation may cause a silent mutation if the mRNA codon codes for the same amino acid, a missense mutation if the mRNA codon codes for a different amino acid, or a nonsense mutation if the mRNA codon becomes a stop codon.
