Answer:
Negatively charged phosphate groups of two strands are aligned distantly from each other in a DNA double helix.
Explanation:
DNA double helix is formed when the complementary bases of two single DNA strands pair with each other. The formation of double-stranded structures places the negatively charged phosphate groups of two single DNA strands away from each other. This is because complementary base pairs are present between the sugar-phosphate backbones of two DNA strands of a double helix. The double-helical structure also concentrates the nitrogenous bases away from the surrounding watery medium. Altogether, these factors stabilize DNA dyad.
The genotype of a normal male zygote is XY, with the X chromosome (sex chromosome) coming from the mother and Y from the father.
According to the characteristics of this organism, it is classified into the Protist kingdom, which brings together unicellular or simple multicellular organisms that do not form tissues, both autotrophic and heterotrophic.
<h3>What is the kingdom protista?</h3>
It includes eukaryote-type organisms that, due to their characteristics, cannot be included in the rest of the kingdoms of this class.
Although most protists are unicellular, there are also multicellular protists and they can have autotrophic or heterotrophic metabolisms.
Therefore, we can conclude that the protist kingdom groups living beings that have cells belonging to the eukaryote group.
