Are all DNA mutations detrimental?
Nope! Sometimes mutations are "silent mutations", this means that changing out the base does not change the amino acid made (as many amino acids are coded by about 3 different base combinations) Also, the mutation may only swap out an amino acid with a similar one, causing no change in the function of the protein it codes for. A lot of times, several AA's can be altered (even w/ very different AA's), and the protein structure/function can remain the same. Also.... DNA mutations that result in phenotypic mutations are sometimes a good thing: hence evolution... many small mutations causing an advantage over time. :) So mostly mutations that cause a base to swap out for another one are safe. Those that delete or insert a base change the reading frame and that's bad!
Substances used to increase the rate of mutations?
Mutagens are substances that increase the rate of mutations by altering DNA, causing changes in the genetic material of an organism. Common mutagens include UV radiation, certain chemicals like ethidium bromide, and some viruses. These mutagens can lead to errors in DNA replication, resulting in genetic mutations.
What is gene rearrangement?
Gene rearrangement actually means the rearrangement of gene in chromosomes. This can occur through 3 different ways which are inversion, translocation and transposition. These can definitely alter the chromosome and cause mutations to occur.
What is the importance of mutations to life on earth?
Mutation in it self, serves as the way a species adapts. Mutations can be natural or man-made/influenced. "The strong survive" that is the most important thing about mutation. But for a species to adapt it is necessary to have a diverse genetic population. When the environment changes the part of the population best adapted to the new circumstances propagate and survive best. But in general a member of a species is often able to adapt its genetics to an environmental situation. For example when people who live on sea level move to higher regions, then in a few generations the people adapt to the new environment (thinner air, less oxygen). These changes can be genetic, but not necessarily the product of evolution.
What are three main ways that variations in genotype arise in population?
Variations occur due to mutations. There are three factors of mutations which impact the formation of new genotypes. 1) Point Mutations - Very small impact mutation which still might enhance the protection against environment and reproduction. 2) Mutations that alter Gene number and sequence - has major role in evolution as it might help to add new functions. 3) Mutation Rates - In animals and plants mostly very slow, however, prokaryotes due to high rate are able to mutate very fast.

What is the name for a change in DNA?
The answer is Mutations! The 3 basic types of mutations are substitution, insertion, and deletion.
What are 3 biotic factors that can effect an organism after death?
Decomposers, such as bacteria and fungi, break down the organism's remains. Scavengers, like vultures or insects, consume the dead organism. Predators may feed on the scavengers that are consuming the dead organism.
What are 3 ways that alcoholism and drugs abuse effect society?
tax payers money, crime, and poor neighborhoods

What are 3 genetic mutations?
substitution and deletion, frameshift, translocation
How does light effect plant growth?
Light effect plant in 3 ways , 1: blue and red light effect photosynthesis , Photo peroid effects flowering in plants , . Light of different color effect cell division and enlargement .
What are the various kinds of mutations?
Mutations differ and change according to many factors: 1- Site of occurrence: -Genetic mutations -Chromosomal mutations 2- The inheritance: -Somatic mutations -Gamete mutations 3- The origin: -Spontaneous (natural) mutations -Induced mutations 4- The harmful OR useful effects: -Undesirable mutations -Desirable mutations
Mutations in body cells can sometimes result in?
Mutations in body cells can sometimes result in cancer, a condition where cells grow and divide uncontrollably. Mutations can also lead to genetic disorders, affecting the normal functioning of cells and tissues.
