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.
Gastric juice would digest the stomach lining, resulting in ulcers.
Answer:
the difference is that unsaponifiable lipids do not contain fatty acids at least not as a component of the fundamental structure whereas saponifiable lipids do have fatty acids.
Explanation:
As a further explanation unsaponifiable lipids are lipids that do not contain fatty acids as components of the fundamental structure. On the other hand, complex also known as saponifiable lipids do contain fatty acids, and those fatty acids can be released in a process called saponification which is caused by alkaline hydrolysis.
Answer:
1 new DNA molecule, 1 old molecule is conserved
Answer:
Pancreatic juice, NaHCO₃.
Explanation:
The buffers are the chemical solution which neutralizes the acidic effect and the human body also produces the biological buffers which help maintain the pH.
The pancreatic juice secreted by the pancreas gets drained into the duodenum of the small intestine and neutralizes the effect of the acidic content in the stomach bolus. The pancreatic juice contains the sodium bicarbonate which neutralises the effect of the HCl.
Thus, Pancreatic juice, NaHCO₃ is the correct answer.
