Answer:
Cheek cells are eukaryotic cells
The answer is; B
This type of inhibitors does not bind the active site of the enzyme hence does not compete with the substrate (hence its name non-competitive inhibitors). They bind the enzyme at another site and change its conformation. The substrate may still be able to bind the active site but the efficiency of catalysis can be drastically reduced threatening life. This type of inhibition cannot be cured by increasing substrate levels.
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.
Answer:
A chain of reactions is initiated upon soil flooding leading to reduced (low) soil redox potential (Eh, mV) conditions. These reactions include physical, chemical and biological processes that have significant implications for wetland plants.
Physical science is concerned with the inorganic world, including physics, astronomy, certain types of chemistry, and generally, earth sciences. If it includes non-living things, it is physical science.
