<span>Point mutations are of two types: Substitutions of bases that are the change of one base of DNA by another. And Transitions that are replaced on a pyrrhic basis by another pyrrhic or a pyrimidine by another pyrimidine. Transversions: substitution of a pyrrhic base by another pyrimidine or vice versa. These mutations are negative because they affect only one of the nucleotides, and therefore, only one triplet of bases are affected. When the mutation does not affect the individual it is a silent mutation. Chromosomal mutations Changes in the structure of the diploid chromosomes, where one of the chromosomes has a mutation, will have another normal. They can hinder the process of meiosis in the carrier since it hinders the correct pairing of the homologous chromosomes. It would produce an unfeasible offspring or with mutations.</span>
<h2>Mutation will occur </h2>
Explanation:
Base excision repair operates for small DNA damage such as deaminated bases
- DNA glycosylase plays an important role in cleavage of glycosidic bond of abnormal base (does not cleave phosphodiester bond)
- Uracil is incorrectly paired with guanine then mutation will occur
- The original GC base pair will change into AT base pair(transition of GC to AT)
- Transition is a mutation in which one purine(adenine or guanine) is substituted for other or one pyrimidine(cytosine or thymine or uracil) is substituted for other
<span> polymerases, of which there are many. Understanding which types of polymerases perform which functions under which circumstances will clarify the complexity of this topic. The processes of transcription, making RNA from DNA, and replication, copying DNA from DNA, are major functions that require polymerases to link nucleotides into long chains. </span>
Answer:
When water evaporates, the salt is left behind. The fresh water vapor that condenses into clouds, with many of which drift over land.
