Given below are two statements.
Statement I : A unit formed by the attachment of a base to 1′-position of sugar is known as nucleoside.
Statement II : When nucleoside is linked to phosphorous acid at 5′-position of sugar moiety, we get nucleotide.
In the light of the above statements, choose the correct answer from the options given below. [2023]
Statement I is true but Statement II is false.
Statement I is false but Statement II is true.
Both Statement I and Statement II are true.
Both Statement I and Statement II are false.
(1)
When nucleoside is linked to phosphoric acid (not phosphorous acid) at 5′-position of sugar moiety, we get nucleotide.
The central dogma of molecular genetics states that the genetic information flows from [2016]
Amino acids → Proteins → DNA
DNA → Carbohydrates → Proteins
DNA → RNA → Proteins
DNA → RNA → Carbohydrates
(3)
Genetic information flows from
The correct statement regarding RNA and DNA, respectively is [2016]
the sugar component in RNA is arabinose and the sugar component in DNA is ribose
the sugar component in RNA is 2′-deoxyribose and the sugar component in DNA is arabinose
the sugar component in RNA is arabinose and the sugar component in DNA is 2′-deoxyribose
the sugar component in RNA is ribose and the sugar component in DNA is 2′-deoxyribose.
