Which pair of nitrogen bases will form a bond in a DNA molecule?
The two chains are connected by hydrogen bonding between nitrogen bases to form a long double-stranded molecule.So hydrogen bonding determines which nitrogen bases form pairs of DNA.
Full form of pH?
full form of pH is potential of hydrogen or power of hydrogen
What nucleotides can be held together by weak hydrogen bonds?
DNA contains four nucleotide bases, which are adenine, thymine, cytosine and guanine. The pairs of nucleotides that can be held together by weak hydrogen bonds are purines and pyrimidines.
Is a ladder a frame or shell structure?
frame structure
What are a purine and a pyrimidine that are capable of hydrogen bonding to form the rung structure of DNA called?
Adenine (purine) can hydrogen bond with thymine (pyrimidine), and guanine (purine) can hydrogen bond with cytosine (pyrimidine) to form the rungs of the DNA double helix structure.

What is the most likely charge on an ion when hydrogen forms an ion?
When hydrogen forms an ion, it is most likely to have a charge of +1, forming a hydrogen ion (H+). This is because hydrogen has one electron in its outer shell, so it tends to lose this electron to achieve a stable electron configuration similar to that of helium.
Which element will most likely form covalent bonds with fluorine?
Potassium
How many bonds to hydrogen can chlorine have?
Only one bond, as both Hydrogen and Chlorine have one electron in valence shell, so they can have one bond by pairing the electron of last shell to form hydrogen chloride HCL.
Why does hydrogen form h2 molecules?
Hydrogen has one electron, which leaves it with a partially full shell. To have a full shell it must have two electrons. As a result, one hydrogen atom will form a covalent bond with another, ad the two atoms share their electrons.
If Hydrogen atom has 1 electron How many bonds can hydrogen form?
A hydrogen atom can form one bond by sharing its single electron with another atom to achieve a full outer shell of electrons and become stable.
Why is hydrogen electropositive?
Because it has only one electron in its valence shell. Its valence shell holds two electrons so it really wants to share its electron to make a bond of two electrons two fill its valence shell. Thus it is the mose "electron-donating" element. Electronegative elements want electrons so hydrogen donates its electron thus hydrogen is electopositive.
Is hydrogen an ionic bond?
If you mean is the bond in hydrogen gas, H2 ionic then the answer is no.
Does helium have a complete outer shell?
Not by itself, no (that is, hydrogen is not a noble gas). A neutral hydrogen atom starts out with 1 electron, but it needs 2 electrons to fill its shell. Therefore, a hydrogen atom will often form 1 covalent bond with another atom, in order to gain that 1 extra electron it needs to fill its shell. Important note: Most elements need 8 electrons to get a full shell, but hydrogen is the exception: it only needs 2 electrons to get a full shell.
Is neon not likely to form a bond yes or no?
The element Neon is not likely to form bonds with other atoms. This is because Neon has eight electrons in its outer valence shell.
How many Covalent bond does hydrogen form?
Hydrogen typically forms one covalent bond. It has one electron that it can share with another element to complete its valence shell.
Is nitrogen likely to form a bond?
Nitrogen is likely to form covalent bonds with other elements to complete its valence shell of electrons. Nitrogen typically forms triple bonds with itself or with other nonmetals due to its electron configuration.
