Answer:
Chemically altered nucleosides derived from canonical ribo-or deoxyribonucleoside-derivatives of adenosine, cytosine, guanosine, and uridine or thymidine are found in all types of nucleic acids, DNA and RNA. They are particularly abundant in noncoding RNAs, such as transfer RNAs and ribosomal RNA of higher organisms. By increasing the structural diversity of nucleic acids, modified nucleosides play important roles in gene expression and in regulating many aspects of RNA functions. They also contribute to nucleic acid stability and to protection of genetic materials against virus aggression. In this chapter we present a historical overview of the discovery, occurrence, and diversity of the many naturally occurring modified nucleosides that are present in both DNA and RNA of diverse organisms. We also briefly describe the different enzymes that accomplish these nucleic acid ‘decorations’. More information about the structure, function, biosynthesis and evolutionary aspects of selected modified nucleosides in DNA and RNA and their corresponding modification enzymes can be found elsewhere in this volume.

A lot of words how to eat how to hit how to give you a kiss how to take a bath.
i have a baby cousin and she's that old and she love's taking bath's eating and talking.
Answer: Food safety is important for our health not to over eat and I've heard that if you're over weight you have less years of living. But I don't really think that happens in all cases.
For foods u can put fruits, vegetables,meat,protein,carbs
An oral antibiotic should be administered over the next 24 hours divided into 6 evenly spaced doses of 500 milligrams (0.5 grams) of antibiotic in each dose.
The calculation consists of dividing the amount of doses by the weight of the substance.
<h3>What is antibiotic?</h3>
Antibiotics are substances capable of eliminating or preventing the multiplication of bacteria, so they are used in the treatment of bacterial infections. His discovery revolutionized the history of medicine, as previously many people died from various types of infections.
With this information, we can conclude that Antibiotics are drugs of natural or synthetic origin that inhibit the growth or kill of bacteria.
