19 kwi 2010 · The document discusses various types of point mutations including single nucleotide polymorphisms (SNPs) that involve changes to one nucleotide. 2. It provides examples of how mutating a single codon in an mRNA through different point mutations can result in missense, silent, or nonsense mutations. 3.

6 paź 2015 · Mutations can occur in somatic cells or germ cells and be transmitted to offspring. Common gene mutations include point mutations, insertions, deletions, and frameshift mutations, which alter protein production. Mutation is an important source of genetic variation and has applications in crop improvement. Read more.

26 sie 2014 · Induced mutations • Introduction of mutations by mutagens. • Mutagens induce mutations by at least three different mechanisms. • Incorporation of base analogs. • Specific mispairing. • Base damage.
1 mar 2014 · 1. Point mutations affect single sites on DNA • Substitution of 1 base for another • Deletion/addition of a single base • Deletion/addition of a small number of bases • If purine (A/G) or pyrimidine (T/C) substitutes for itself = transition substitution • If purine substitutes for pyrimidine or vice versa = transversion substitution
