Is there double and triple bonds present in DNA?

Answer 1

DNA is made up of double and triple bonds. If you remember the nitrogenous basis i.e. adenine. guanine, cytosine and thymine, where adenine pairs with thymine by double bond and guanine pairs with cytosine with triple bonds.

Answer 2

Single bonds are the longest and weakest of the bonds. A double bond is a sigma bond plus a pi bond, it is stronger than the single but weaker than the triple. The triple bond is a sigma bond plus two pi bonds. A triple bond between he same two elements is shortest and strongest

Answer 3

A double bond comprises of 1 sigma bond and 1 pi bond. A sigma bond is formed by end on or head on overlap of orbitals { bonding}of both the carbon atoms, where as a pi bond is formed by sidewise overlap of p orbitals of adjacent carbon atoms...involved in the chemical reaction.

Answer 4

A little confused by the question, but here are possible answers:

1) Nucleic acids are a linear, unbranched polymer of nucleotide monomers. Nucleotides consist of a phosphate group, ribose, and nitrogenous base. Both the phosphate group and the nitrogenous bases contain double bonds.

2) DNA exists as a double strand (dsDNA). Among the interactions that holds the two single strands together is hydrogen bonds between the complementary bases. The complementary bases have either two (A=T or A=U) or three (G≡C) hydrogen bonds between them.

3) RNA exists as a single strand, but it takes on conformations that are double stranded where the single strand pairs with itself. The double stranded portions are held together by the same types of interactions and bonds as dsDNA.

Answer 5

No, double and triple bonds are not present in DNA. DNA consists of four types of nitrogenous bases that form hydrogen bonds with each other to create the double helix structure. These bases are adenine, thymine, cytosine, and guanine.

Answer 6

Adenine bonds to thymine (double bond) Cytosine binds to guanine (triple bond)

Answer 7

i think this can be formed

Answer 8

DNA contains both single and double bonds
