WebRNA is a polymer of ribonucleotides. RNA differs from DNA in three basic respects. First, RNA employs uracil as a nitrogenous base, in place of the thymine used in DNA. Second, RNA nucleotides possess a hydroxyl group at the 2′ position, while DNA is deoxygenated at that position to a proton. WebDNA is a polymer of ribonucleotides. 11%. B All carbohydrates breakdown into glucose. 17%. C Sequence of amino acids determines primary protein structure. 56%. D RNA is single stranded and contains different purine bases other than in DNA. 17%. Solution: Correct answer is (c) Sequence of amino acids determines primary protein structure.
WebFeb 3, 2024 · Figure 6.3. 1: (a) Ribonucleotides contain the pentose sugar ribose instead of the deoxyribose found in deoxyribonucleotides. (b) RNA contains the pyrimidine uracil in place of thymine found in DNA. The RNA-specific pyrimidine uracil forms a complementary base pair with adenine and is used instead of the thymine used in DNA. WebJan 11, 2024 · Phosphorylation for ribonucleotide formation is a critical step in the origin of life but has had limited success due to the thermodynamic and kinetic constraints in aqueous media. Here, we report that the production of ribonucleotides from ribonucleosides in the presence of monopotassium phosphate (KH2PO4) spontaneously proceeded in …
In biochemistry, a ribonucleotide is a nucleotide containing ribose as its pentose component. It is considered a molecular precursor of nucleic acids. Nucleotides are the basic building blocks of DNA and RNA. Ribonucleotides themselves are basic monomeric building blocks for RNA.
