WebOct 7, 2024 · The chains are interconnected, either by chemical cross-links or physical entanglements, and form a network. Pulling on the material causes the chains to straighten, and interchain connections distribute the applied mechanical load. These connections prevent the chains from slipping past one another and give rise to a solid-like response. WebMay 30, 2024 · Covalent Schiff base complex of YedK C2A and abasic DNA. Covalent Schiff base complex of YedK C2A and abasic DNA. ... (AP, or abasic) sites in DNA are one of the most common forms of DNA damage. AP sites are reactive and form cross-links to both proteins and DNA, are prone to strand breakage, and inhibit DNA replication and …

WebOct 7, 2024 · The utility and lifetime of materials made from polymer networks, including hydrogels, depend on their capacity to stretch and resist tearing. In gels and elastomers, those mechanical properties are often limited by the covalent chemical structure of the polymer strands between cross-links, which is typically fixed during the material synthesis. WebCovalent cross-links both between and within the tropocollagen molecules confer strength and rigidity on the collagen fiber. These cross-links are formed between Lys and its … chucky the game

WebCorrect answer option d. Shashi structure of protein form disulfide linkage (-SH) for stabilization. Rest of the options are incorrect because disulfide linkage between sulphur containing amino acid is more stable. 2. Given statement is true Oxyge …. Which of the functional groups shown helps stabilize proteins by forming covalent cross-links ... In genetics, crosslinking of DNA occurs when various exogenous or endogenous agents react with two nucleotides of DNA, forming a covalent linkage between them. This crosslink can occur within the same strand (intrastrand) or between opposite strands of double-stranded DNA (interstrand). These adducts interfere with cellular metabolism, such as DNA replication and transcription, triggering cell death. These crosslinks can, however, be repaired through excision or recombinati… WebAug 31, 2024 · The formation of covalent bonds which hold portions of several polymer chains together is called cross-linking. Extensive cross-linking results in a random three-dimensional network of interconnected chains, as shown in the figure. chucky the killer clown
