    1. Spontaneous Mutation -> it is a mutation that arises naturally and not as a result of exposure to mutagens. It arises from a variety of sources which may include: errors in DNA replication, spontaneous lesions, and transposable genetic elements. Non-spontaneous/ Induced Mutation -> a mutation that is produced by treatment with a physical or chemical agent that affects the DNA molecules of a living organism. It may arise in a variety of ways such as exposure to ultraviolet or ionizing...

  • Mutations - 282 Words
    Mutations can lead to genetic variations by producing random changes in an organism’s genetic coding. This causes a different protein to be produced, or none at all. Mutation usually has a negative effect due to an important protein and enzyme not being produced, so the organism cannot preform its original function. According to the chart the BRCA1 mutation is more dangerous than the BRCA2 mutation. This is due to the fact the chart shows that a higher percentage of women with the BRCA1...

    In biology, term- mutation has been described as changes to the base pair sequence of the genetic material of an organism. Mutations can be caused by: copying errors in the genetic material during cell division, by exposure to ultraviolet or ionizing radiation, chemical mutagens, or viruses, or can occur deliberately under cellular control during processes such as hypermutation. In multicellular organisms, mutations can be subdivided into germ line mutations, which can be passed on to...

    A gene is a long sequence of nucleotides on a DNA molecule. A mutation is a change in the amount of an organism's genetic material and when a change in genotype produces a change in phenotype, the individual affected is said to be a mutant. A gene mutation involves a change in one or more of the nucleotides in a strand of DNA. The sequence of nucleotides in a gene controls the order in which amino acids are made into a protein, therefore if the sequence of nucleotides in a gene is altered by a...

    In studying evolution, there has been much debate over the origins and evolutionary maintenance of sex. This represents a great challenge in evolution as it appears that the vast majority of animals and plants reproduce sexually. One component compounding the mystery is the two fold cost of sex, that is, there is a cost to producing males. Where an asexual species can double its population each generation, the sexual species will remain at a constant population if both populations produce 2...

For centuries Tay-Sachs has been seen in many ethnicities, but one statistic that surprised the scientist was the fact that Ashkenazims (or also known as Eastern European Jews) appeared to have the disease a hundred times more frequently.
