Answer:

Hello! DNA (Deoxyribonucleic Acid) is a molecule composed of two polynucleotide chains, which coil around each other to form a double helix that carries genetic instructions for the development, functioning, reproduction and growth of all known organisms and many viruses. DNA and the instructions contained in it passes from adult organisms to their offspring during the process of reproduction. Hope this helps ! :)

The cells of certain eukaryotic organisms, such as vertebrates and plants, often methylate the cytosines in their DNA, producing
stich3 [128]

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.

Why is algae classified in the Protist Kingdom and not the Plant Kingdom even though they are photosynthetic? Research why some
KengaRu [80]
Algae are photosynthetic, but they are also unicellular organisms (Euglena) and shares some of the common features with plants as well as animals. They move like animals and perform photosynthesis like plants. Therefore, they are classified into Protists, and not the Algae. Their most features resemble the non-photosynthetic protozoa, and not plants, and therefore, are put into the Protista. 
They also lack a cell wall, which is a feature of plants.
Some scientists advocate their classification in plants because of their sexual mode of reproductiona, and formation of spores.
