Shipments of live animals, including poultry, reptiles, and bees, have very specific packaging requirements. Although you can drop these animals at any Post Office location, they are only shipped when the right transportation is available. With a few exceptions, pets and warm-blooded animals may not go in the mail.
A series of codons in part of a messenger RNA (mRNA) molecule. Each codon consists of three nucleotides, usually corresponding to a single amino acid. The nucleotides are abbreviated with the letters A, U, G and C. This is mRNA, which uses U (uracil).DNA uses T (thymine) instead.he portion of the genome that codes for a protein or an RNA is called a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid. Each nucleotide sub-unit consists of a phosphate, a deoxyribose sugar, and one of the four nitrogenous nucleobases.
The codon is a set of 3 nucleotides that can be read to convey a message in your DNA. It can be a code saying to start the process of protein synthesis, or stop it, or to encode for an amino acid - the building blocks of proteins.
