If you are talking about U as a chemical symbol, U would be the element uranium.
The U stands for uracil. But remember, that uracil is only in RNA. In DNA the U is replaced with T (thymine).
The letter "u" is used in DNA sequences to represent deoxyuridine, which is a base found in RNA but not in DNA. In RNA sequences, "u" stands for uracil instead of thymine, which is found in DNA sequences.
The letters in DNA stand for the four nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up to form the genetic code that carries instructions for building and maintaining living organisms.
Deoxyribose Nucleic Acid
Adenine (A) Thymine (T) <--only in DNA Guanine (G) Cytosine (C) Uracil (U) <--only in RNA A pairs with T in DNA A pairs with U in RNA G pairs with C in both DNA and RNA
The "A" in DNA stands for adenine.
DNA stands for Deoxyribonucleic acid
DNA is an abbreviation for Deoxyribonucleic Acid.
DNA does stand for deoxyribonucleic acid and you spelled it exactly right.
deoxyribonucleic acid
The U stands for uracil. But remember, that uracil is only in RNA. In DNA the U is replaced with T (thymine).
DNA - Deoxyribonucleic acid RNA - Ribonucleic acid
A (adenine) goes with U (uracil) in RNA.

In RNA, the nitrogenous base of U (Uracil) is in place of T (Thymine) in DNA.
