Explain the double helix structure of DNA molecule. - Toppr
The characteristics of the double helical structure of DNA proposed by Watson and Crick are as follows i) The structure of DNA molecule resembles a spirally twisted ladder. ii) It is made of two …
Explain the double helix structure of DNA with a labelled diagram.
DNA has a double-stranded helical structure. It was given by Watson and Crick model. It is also known as B form of DNA. It is made up of nitrogenous base, deoxyribose sugar, and phosphate. The …
List the salient features of double helix structure of DNA. - Toppr
The salient features of double helix structure of DNA are as follows: There are two polynucleotide chains in a double stranded DNA. The backbone is constituted by sugar phosphate. The two strands …
Explain the two factors responsible conferring stability to double ...
The factors conferring stability to ds DNA: Base pair stacking i.e., the individual bases form a strong stacking interaction thereby providing stability to the double helix. Hydrogen bonds between the …
Write any four salient features of the Double helix structure of DNA.
The salient features of double helix structure of DNA are as follows: There are two polynucleotide chains in a double stranded DNA. The backbone is constituted by sugar phosphate. The two strands …
Base stacking destabilise DNA double helical structure.
Each chain in DNA constitute sugar-phosphate backbone, Two chains are coiled in right-handed fashion in case of B-DNA and the pitch of the helix has roughly 10 bp in it. However, apart from it the base …
In DNA you which type (s) of bond? - Toppr
The DNA double helix polymer of nucleic acid held together by nucleotides which base pair together. In B-DNA, the most common double helical structure found in nature, the double helix is right-handed …
Unwinding of DNA is done by - Toppr
Helicases move along the double-stranded DNA and separate the strands by breaking hydrogen b onds at the expense of energy from ATP. DNA unwinding by helicases creates topological stress in the …
