Answer:
two nucleotides are deleted
Explanation:
Frameshift mutations arise when the normal sequence of codons is disrupted by the insertion or deletion of one or more nucleotides, provided that the number of nucleotides added or removed is not a multiple of three.
Because two nucleotides are deleted (2 is not divisble by 3), it would be a source of a frameshift mutation.
Hope this helped! :^)
Denitrification is the major process involved in converting nitrogen components present in the nitrogen gas and it is released into the atmosphere.
<u>EXPLANATION: </u>
With the help of the nitrogen cycle, the nitrogen that enters living things by nitrogen fixation is converted back into nitrogen and is released in the atmosphere by microbes.
The nitrogen-fixing bacteria converts the nitrogen contents into ammonia by the process called ammonification. Then it oxidizes ammonia to nitrite by the process called nitrification and these nitrates are absorbed by plants.
Then, the bacteria present in the soil convert nitrate back to nitrogen gas which is released back to the atmosphere.
