WebAlessandra di Masi, in Reference Module in Life Sciences, 2024. Ribonucleotide excision. Ribonucleotides are normally incorporated into the DNA as primers for lagging strand synthesis, after which they are removed by an exonucleolytic action. Occasionally, the incorporation of ribonucleotides in place of deoxyribonucleotides has been observed … 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 …
WebCondensation polymers form more slowly than addition polymers, often requiring heat, and they are generally lower in molecular weight. The terminal functional groups on a chain remain active, so that groups of shorter chains combine into longer chains in the late stages of polymerization.

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.
