Causes and Mechanisms of Mutation Mutations That Occur In Germ Cells (sperm, Eggs) Are Passed On PPT. Mutations that are in the somatic tissues of the body. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication (translesion synthesis). Mutations in somatic (body) cells may be harmless, or may result in disease such as - ...

Small deletions may remove one or a few base pairs within a gene, while larger deletions can remove an entire gene or several neighboring genes. - Mutagens, such as UV ray and chemicals, can cause mutations.  Changes in the nucleotide sequence of DNA May occur in somatic cells (aren’t passed to offspring) May occur in gametes (eggs & sperm) and be passed to offspring. Winner of the Standing Ovation Award for “Best PowerPoint Templates” from Presentations Magazine. 1. They result from small changes in the genetic material (single gene mutations), rearrangements in chromosome structure (chromosome mutations), or changes in chromosome number( genome mutations). - MUTATIONS Germ Cells (Sex Cells) Changes can occur in egg/sperm before, during or after meiosis Altered egg/sperm may be fertilized passing change to offspring ... - Mutations What is a mutation? 3. Gene mutation: Mutation or series of mutations occur in the polynucleotide sequence of a gene that changes the function of it is referred to as gene mutations. Or use it to find and download high-quality how-to PowerPoint ppt presentations with illustrated or animated slides that will teach you how to do something new, also for free. Causes of gene mutation: Genetic abnormalities may occur naturally or may be caused by a mutagenic source depending on the environment. It's FREE! The types of mutations include: Missense mutation. A mutation whose gene product adversely affects the normal, wild-type gene product within the same cell Usually by dimerize (combining) with it. Here we can say that the condition caused by mutation in one or more genes is called a genetic disorder, these genetic disorder causes the disease by making a gene function improperly. Somatic mutations 1. Ionizing radiation - damages DNA by causing the formation of “free radicals” leading to mutations. 2. A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Genes contain instructions for making proteins, Protein building blocks are called amino acids, Amino acids are strung together into long, linear, In general, a gene encodes the instructions for, When a gene is misspelled, the protein made, An amino acid building block of a protein, Codons identified in the Genetic Code Table, START PROTEIN HERE AUG (START) Methionine, Amino acid building blocks N-Met-Glu-Tyr-C, Codons are identified in the Genetic Code Table, Archibald Garrod (1902) described alkaptonuria, a, (1) Normal DNA and amino acid sequence makes a, (2) Mutation in DNA changes Trp to Stop to make a, Mistakes made when the DNA is replicated (wrong, Ultra violet (UV) light and ionizing radiation, Environmental chemical carcinogens can damage DNA, Molecular fragmentationproteins, enzymes, and, Free radical generationmolecules of susceptible.

MUTATIONS Mutation are heritable changes in the genetic material. The mutation may result due to changes either on the gene or the chromosome itself. Some mutations affect a single gene, ... - G protein Mutations Causing Disease LiYang GPCRs are known for their physiological functions. Mutations are not transmitted to progeny. - ...

Mutation rate depends on species and on gene Generally, mutations are random Hot spot: ... - Cancer: causes and treatment Telomeres are non-gene DNA at the ends of DNA strands. Examples of potentially harmful environmental factors include toxic chemicals, X-rays and pollution. Mutations may be caused due to effects of physical agents and chemical agents. 4. Causes of Gene Mutation Gene mutations are most commonly caused as a result of two types of occurrences. 296 - 301 Objectives Categorize different kinds of mutations that can occur in DNA. Environmental factors such as chemicals, radiation, and ultraviolet light from the sun can cause mutations. This type of mutation can cause the resulting protein to function improperly.

A mutation in the gene controlling the cell division leads to cancer. fAre Mutations Helpful or Harmful? Random mutations in the environment are essential in natural evolution, where mutations occurring in gametes which are inheritable sometimes give rise to new alleles that are selectively advantageous.
