Clonidine should not be used by people who have a known allergy to this drug. If a person has underlying depression, clonidine should be used with caution and under close physician supervision. Clonidine should not be abruptly withdrawn but rather, slowly decreased over several days to avoid withdrawal symptoms.
Three ways mutations can occur in genes are: 1. Insertion: Extra DNA nucleoties are added to the DNA strand. 2. Deletion: DNA nucleotides are deleted, therefore, changing the â¦ DNA sequence. 3. Translocation: parts of chromosomes are exchanged.or example, this can happen during crossover during the formation of gametes. Substitution mutations happen when one nucleotide (the smallest unit of DNA) is replaced by another. These are caused by a number of chemicals that look like something in between both of those nucleotides.
There are many possible types of mutations possible in chromosomes. In the case of a point mutation, there is a change in a single nucleotide. Other mutations can be more dramatic. A large segment of DNA can be deleted, duplicated, inverted, or inserted in the wrong place.These mutations usually result in a non-functional protein, or a number of non-functional proteins.utations can arise in DNA through deletion, duplication, inversion, insertion, and translocation within the chromosome. A deletion is when a segment of DNA is lost from the chromosome. A duplication is when a segment is repeated.
