What is the difference between a chromosomal and gene mutation?
Genetic alternations include chromosomal abnormalities and gene mutations. Chromosomal abnormalities generally arise during cell division. ... Gene mutations are permanent changes in DNA gene sequence. They can arise during normal DNA replication or in response to environmental factors.
What is the difference between a gene mutation and a chromosomal mutation quizlet?
What is the difference between a gene mutation and a chromosomal mutation? A gene mutation affects a single gene, and is usually caused by a replication error. A chromosomal mutation affects part or all of a chromosome, and is usually caused by an error in meiosis. ... A mutation is a change in DNA.
What do you mean by chromosomal aberration or mutation?
Chromosome aberrations include changes in chromosome number (gains and losses) and changes in structure (deletions, inversions, and exchanges). ... Structural chromosome changes can lead to birth defects, cancer, and other late onset disease outcomes.
What are the different types of gene and chromosomal mutations?
There are four different types of chromosomal mutations: Deletions, Translocations, Duplications and Inversions (pictured below). Note that any chromosome mutation resulting in a significant loss of genetic material (Deletion) is most likely to be lethal.
