Today is the third lecture with Prof Khatty on Microbial
Genetic. The more we studied this topic the more difficult I found it. HUH L
Today I learnt about Mutation.
Mutation is any inheritable change in the base sequence of DNA.
There are two types of mutation :
1.
Base substitution
·
Silent
·
Missense
·
Nonsense
2.
Frameshift mutation
·
Insertion or deletion
·
Shift in the reading frame
Mutation rate is the probability that a gene will be mutated
in a single generation
Mutation frequency is the frequency at which a specific kind
of mutation (or mutant) is found in a population of individuals.
There are types of mutagen such as :
·
Base analogues
·
Chemical mutagen
·
Radiation
·
Intercalating agents
That’s all from me, till we meet again. Assalamualaikum
