a unit formed by attachment of a base to___ position of sugar is known as nucleoside
A nucleoside is formed when a nitrogenous base is attached to the C1 (carbon 1) position of a sugar molecule. Nucleotides are then formed when one or more phosphate groups are attached to the nucleoside.
two nucleosides are joined together by phosphodiester linkage, this linkage is formed between _________ of one sugar and ______ of other sugar.
In nucleic acids, a phosphodiester bond is formed between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another. This linkage is crucial in the formation of the backbone of DNA and RNA.
structure of DNA is look alike _________
who proposed that structure of DNA is double helix ?
The double helix structure of DNA was proposed by James D. Watson and Francis H.C. Crick in 1953. They described how two DNA strands form a helical structure held together by complementary base pairing.
by which bond , base of one nucleotide and base of another nucleotide are joined together ?
In DNA, the bases of one nucleotide are joined to the bases of another nucleotide by hydrogen bonds. Adenine pairs with thymine via two hydrogen bonds, and cytosine pairs with guanine via three hydrogen bonds.
which pairs of bases are true for linkage between two chain of polynucleiotide ?
In the double-helix structure of DNA, adenine (A) pairs with thymine (T) using two hydrogen bonds, and guanine (G) pairs with cytosine (C) using three hydrogen bonds. Therefore, adenine-thymine is the correct base pair.
how many hydrogen bonds between base G and Base C are present in structure of DNA ?
In the DNA structure, guanine (G) forms three hydrogen bonds with cytosine (C). This triple bonding contributes to the stability of the DNA molecule.
if a person bleeds by his gingiva , so what would you suggest to eat to prevent the disease ?
Bleeding gums, or gingival bleeding, can be a sign of Vitamin C deficiency, also known as scurvy. Citrus fruits like oranges, lemons, and grapefruits are rich in Vitamin C and can help prevent this condition.
which subgroup isn’t possible for vitamin ?
Vitamin B4 is not recognized as a vitamin by modern science. The B vitamins include B1 (Thiamine), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine), B7 (Biotin), B9 (Folate), and B12 (Cobalamin). Therefore, B4 is not a possible subgroup for vitamins.
__________term is familiar for vitamin nowadays
The term 'vitamin' is the correct and familiar term used nowadays. The term 'vitamine' was originally coined by Casimir Funk in 1912, but the 'e' was later dropped.
