Answer:
The G-T mismatches generally originate because of the spontaneous deamination of 5-methylcytosine to thymine. Therefore, correcting G-T to G≡C most probably preserves the original sequence.
In the DNA, the 5-methylcytosine usually goes through the process of deamination to thymine. This transformation may cause a G-T base pair or mismatch of nucleotide pairs. Generally, the mutation like C-T transition is common. The G-T base pair is identified by base excision repair proteins, which withdraws this mismatched base pair.
The repair system encourages methylation of cytosine as the mechanism of the regulation of transcription, which permits the turning off or on the process of transcription on the basis of the requirement of the cells. This also assists in preventing the mutation of DNA.
<span>Risks of emphysema, asthma and cancer are associated with the tars and hydrocarbons in inhaled smoke. The tar acts to coat the bronchial sacs, in effect causing the bronchial sacs to be damaged beyond repair and suffocating the smoker over time. The hydrocarbons contain cancer causing chemicals that enter the blood stream and are carried throughout the body.</span>
