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.
A phosphate group is attached to the 3' position of one ribose and the 5' position of the next. The phosphate groups have a negative charge each, making RNA a charged molecule (polyanion). The bases form hydrogen bonds between cytosine and guanine, between adenine and uracil and between guanine and uracil.
