The Chernobyl Disaster
Mutations
A mutation is a type of change that happens in our DNA sequence. Some of the most common mutations are, a duplication where a body part is copied one or more times. Some more common mutations are a deletion where the number of DNA bases are changed, and another common mutation is an insertion where more DNA bases are added. A nucleotide mutation repeats short DNA sequences a number of times in a row. A substitution is where one or more bases in the DNA sequence is replaced by the same number of bases.
There were many short and long term effects after the Chernobyl disaster that would affect plants, animals, and humans. One of the animals that was affected nearby was a mutated catfish in the Pripyat River. The radioactivity from the

    The first disparity between the Chernobyl and Fukushima accident is the causes. The Chernobyl accident was caused by human error in conducting the plant outside its technical specifications and failure to notify the proper authorities following the accident. Chernobyl’s power plant also had a faulty nuclear reactor design which exclude a containment structure typically found in most nuclear power plant. The two contributing factors usher the nuclear reactor to explode and failure to contain discharge of radioactive materials into the atmosphere. In contrast, the Fukushima accident precipitate due to natural disaster consist of earthquake and tsunami causing a malfunction of the plant’s cooling system. Unlike Chernobyl, Fukushima’s nuclear plant…

    Mutation is a change in the nucleotide arrangement of a short locale of a genome. Numerous mutations are point mutations that supplant one nucleotide with another; others include insertion or deletion of one or a couple of nucleotides. Mutations result either from errors in DNA or from the harming impacts of mutagens, for example, chemicals and radiation, which respond with DNA and change the structures of individual nucleotides. All cells possess DNA-repair enzymes that attempt to minimize the number of mutations that occur. These enzymes work in two ways.…

    Mutations are alterations in the nucleotides that change the amino acid sequence within the genotype of an organism; mutations can occur from either insertion or deletions of nucleotides in a protein . The protein created from the base pairings of a mutated nucleotide may result in the making of an incorrect protein . Mutations, in important genes, may cause the cell to die if the gene synthesizes a defective protein. Muttions can occur in a few nucleotide pairs as well as long segments of DNA. A nucleotide pair substitution is an example of a small-scale mutation ; it is the replacement of one nucleotide and its pair with another pair of nucleotides. A change in an amino acid sequence may not always result in any changes on the encoded protein.…

    DNA is a self-replicating material that is in almost all living organisms as the main part of chromosomes. Ribonucleic acid or RNA is a nucleic acid that is in all living cells. Its main role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins. A mutation is a part of your genetic code that is changed. So your genetic code is made up of sections called codons and each codon is made up of three nucleotides. A genetic code is like a sentence. The mad cat ate the fat rat and the big bat. So this sentence would be your genetic code it all makes sense and isn't messed up anywhere. But let's say the mutation in frame error occurs which means that a section of the sentence is deleted but still makes sense. The mad cat ate the big bat. Without of frame errors it's not the codons or ‘words’ that get deleted it's the nucleotides or letters. The mad cat ate the tra tan dth ebi gba t. So now the sentence is intelligible and doesn't make any sense since the mutation took away fa from fat so the codons all mix and squish together to fill that gap. Duchenne muscular dystrophy is caused by a defective gene that produces dystrophin. it sometimes occurs in people without a family history of Duchenne. Meiosis is a process where a single cell divides twice to make four cells that only have half the original amount of genetic information. These cells are our sex cells; sperm in males, eggs in females.…

    A mutation, occurring during the process of mitosis or meiosis, is a change in genetic code or chromosome. This can affect how one physically looks, behave, and think. Mutations are random. Most are harmless but they can be neutral or harmful to organisms. They can be an advantage when it is seen as a strength or useful in a certain environment. They can be seen as neutral when the mutation produces the same amino acid and not affect anything.…
