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.
Rating Newest Oldest. Best Answer: A codon is a base triplet of nucleotides on a strand of RNA. Ribsomes, when converting from DNA to make proteins by means of Transcription and Translation, are read in terms of three nucleotides, which are codons. But they can also be used for the complementary DNA base triplet.ating Newest Oldest. Best Answer: A codon is a base triplet of nucleotides on a strand of RNA.
