The complementary base pairs in a DNA molecule are stabilized by?
The complementary base pairs in a DNA molecule are stabilized by hydrogen bonds between adenine and thymine, and between cytosine and guanine. These hydrogen bonds help hold the two strands of DNA together in the double helix structure.
How are the nitrogen bases held together in the center of the DNA molecule?
The nitrogen bases are held together in the center of the DNA molecule by hydrogen bonds. These bonds form between specific base pairs: adenine (A) with thymine (T), and guanine (G) with cytosine (C). The hydrogen bonds provide stability to the DNA double helix structure.
Why does a double stranded molecule denature into two single stranded molecules when heated?
The heat breaks the hydrogen bonds that hold the nitrogenous bases together in the centre of the DNA molecule. However, the covalent bonds between the phosphate and deoxyribose sugar are not affected.
The two strands of a DNA molecule are held together by what?
The two strands of a DNA molecule are held together by hydrogen bonds between complementary base pairs. Specifically, adenine pairs with thymine, and guanine pairs with cytosine. This pairing allows for the twisting and unwinding of the DNA molecule during replication and transcription.
Is DNA a single-stranded molecule?
No, DNA is a double-stranded molecule consisting of two strands that are twisted together in a helical structure.
Is hydrogen a molecule?
Yes, hydrogen can exist as a molecule. In its diatomic form, hydrogen atoms can bond together to form a molecule called molecular hydrogen (H2).
Bonds that hold DNA bases together?
Hydrogen bonds hold together the nucleotide bases in a DNA molecule. There are specific base pairings: adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G), connected by hydrogen bonds. These bonds contribute to the stability and structure of the DNA molecule.
What elements are H2?
H2 Is a diatomic hydrogen molecule. It is made up of two hydrogen molecules that are joined together.
What are two of the same atoms nodes together called?
Two atoms of the same element that are bonded together are called a "molecule." For example, two hydrogen atoms can bond to form a hydrogen molecule (Hâ‚‚). When these two atoms are connected, they share electrons, which leads to the formation of a stable chemical structure.
What is the molecular structure of HCl?
HCl is a diatomic molecule composed of one hydrogen atom and one chlorine atom covalently bonded together. Its molecular structure is linear, with the hydrogen atom at one end and the chlorine atom at the other end.
What holds two atoms in a hydrogen molecule?
A hydrogen molecule is held together by a covalent bond, where the two hydrogen atoms share their electrons in order to achieve a stable electron configuration. This shared pair of electrons creates a bond that keeps the atoms together.
Is hydrogen peroxide an atom or an molecule?
Hydrogen peroxide is a molecule. It consists of two hydrogen atoms and two oxygen atoms bonded together.
What helps molecule stick together?
Hydrogen bonds
The two strands of a DNA molecule are held together by?
The two strands of a DNA molecule are held together by hydrogen bonds between complementary nitrogenous bases. Adenine pairs with thymine, and guanine pairs with cytosine. This base pairing allows the two strands to twist together in a double helix structure.
Is hydrogen a molecule and or compound or element?
Hydrogen is an element because it is made up of only one type of atom, which is hydrogen itself. When two hydrogen atoms bond together, they form a hydrogen molecule (H2). So, hydrogen can exist as both an element and a molecule.
Why the mass of hydrogen molecule is greater then the mass of hydrogen atom?
The mass of a hydrogen molecule is greater than that of a single hydrogen atom because a hydrogen molecule consists of two hydrogen atoms bonded together. When two hydrogen atoms bond to form a molecule, they share electrons, resulting in a decrease in the individual mass of each atom. However, the total mass of the molecule is slightly higher due to the binding energy that holds the atoms together.
Is a hydrogen chloride a molecule?
Hydrogen chloride (HCl) is a molecule composed of one hydrogen atom and one chlorine atom covalently bonded together.
