A legacy resource from NICHCY. Welcome to the alphabet soup of special education! The disability community is full of acronyms that people constantly use in writing and in conversation, and itâs important to know what those acronyms stand for. Acronyms are used in order to abbreviate names or phrases.
DNA is negatively charged due to the negatively charged phosphate ions in its structure. DNA carries 2 negative charges per base pair (whose length is 0.34 nm). As a title oâ¦f example, the human DNA has about 6 thousands of million (6 x 10^9) base pairs. This gives a total charge of 12 thousands of million negative charges (12 x 10^9 negative charges), and a total length of about 2 meters.
The DNA molecule is technically classified as a bipolymer, which means that it contains two polymer chains that link up to form the larger molecule. Each of these polymer chains is composed of a DNA monomer, or nucleotide, whose structure is formed from a phosphate group, a deoxyribose sugar and a nitrogen-containing base. The deoxyribose sugar forms part of the backbone of each DNA strand, which line up along the outside of the whole DNA molecule.
