A human DNA molecule consists of two strands that are made up of nucleotides. Each nucleotide contains a phosphate group, a sugar molecule (deoxyribose), and one of four nitrogenous bases (adenine, thymine, guanine, or cytosine). Therefore, a human DNA molecule contains billions of atoms, including carbon, hydrogen, oxygen, nitrogen, and phosphorus atoms. Specifically, a single human DNA molecule can contain over 6 billion atoms.

Well, honey, a human DNA molecule consists of two strands that contain about 3 billion base pairs. Each base pair is made up of atoms including carbon, hydrogen, nitrogen, oxygen, and phosphorus. So, to give you a straightforward answer, there are a heck of a lot of atoms in a human DNA molecule, but who's got time to count them all?
Well, isn't that a happy little question! A human DNA molecule is made up of millions of atoms, all working together to create the unique blueprint that makes you, you. Just like how each brushstroke adds to the beauty of a painting, each atom in your DNA contributes to the masterpiece that is your genetic code.
Oh, dude, you're hitting me with some science now! So, like, a human DNA molecule has about 6 billion atoms. That's a lot of tiny building blocks making us who we are, man. So, yeah, 6 billion atoms, give or take a few.
That's a tough question, but I might be able to give you an idea of how many there actually are... Human DNA is divided into 23 paired chromosomes, 22 pairs of autosomes and 1 pair of sex chromosomes. There are about 3 Billion nucleotide pairs packed away in there, most of it inactive at any one point in time. It's believed that much of the DNA is inactive, meaning that it is not currently expressed, and therefore not responsible for creating proteins. However, the inactive DNA could be responsible for early fetal development; we aren't entirely sure what all of the DNA does, although all of it has been mapped out... Now back to the initial question. A molecule is defined as 2 or more atoms connected by chemical bonds. Each DNA strand is comprised of two Phosphate Deoxyribose backbones, held together by nucleotides (Adenine, Cytosine, Guanine, and Thymine), bound by Hydrogen bonds. So technically, every DNA segment that's connected is one molecule...therefore, there are 46 molecules of DNA in each human cell. But, if what you were asking how many molecules are assembled for the DNA in each cell, I'd bet 4 per each nucleotide, 1 for each side of the backbone, and 1 for each nucleotide pair. That's about 12 Billion molecules, but they are joined by chemical bonds, and therefore are not individual molecules anymore once assembled.
A single unit of DNA is called a nucleotide.
A nucleotide is made up of a pentose sugar called deoxy ribose, a nitrogenous base and a phosphate group.
Each molecule of deoxyribose has 5 carbon atoms + 10 hydrogen atoms + 4 oxygen atoms
= 19 atoms
There are four kinds of nitrogenous bases in DNA:
Adenine, thymine, guanine, cytosine
Adenine has 8 atoms in it
Guanine has 16 atoms
Thymine has 6 atoms
Cytosine has 7 atoms
Phosphate group has about 4 atoms.
So the total value is about 29-39 atoms.
A human DNA molecule consists of about 6 billion atoms. These atoms are arranged in a specific sequence that encodes genetic information.
DNA only has 5 different atoms - carbon, hydrogen, oxygen, nitrogen and phosphorous.
According to one estimation, there are about 204 billion atoms in each DNA .
It depends on the species but humans have 23 pairs or 46 chromosomes (DNA molecules) total.
Trillions of cells in the human body but it may not true because cell can die every time
The basic structural unit of molecular compounds is the molecule. A molecule is a group of atoms bonded together, representing the smallest unit of a compound that retains its chemical properties. Molecules can be simple, consisting of just two atoms (like oxygen gas, O2), or complex with many atoms bonded together (like DNA).
The sides of the DNA molecule are made up of repeating sugar-phosphate groups, not nitrogen bases. The nitrogen bases are arranged in the middle of the DNA molecule and form the rungs of the double helix structure.
Hydrogen bonds play a crucial role in various biological processes, such as the formation of DNA double helix, protein folding, and water's unique properties. They result from the attraction between a hydrogen atom covalently bonded to an electronegative atom (like oxygen or nitrogen) and another electronegative atom nearby. This weak interaction helps maintain the structure and stability of many biological molecules.
A water molecule is bigger than a carbon atom. A water molecule consists of three atoms (two hydrogen and one oxygen), whereas a carbon atom is a single atom.
DNA is a biotic molecule because it is found in living organisms and is essential for their genetic information and inheritance.
