Answer: The following which is not true is letter A.
Explanation: Because microtubules require GTP hydrolysis. The process requires energy from GTP hydrolysis. It occurs at the beta- tubulin subunit after incorporation of the tubulin dimer into the microtubule lattice.
Answer:
Some statements of the question are missing but it can be understand as the Hydrogen bonds are Easy to break, Less amount of heat required, Less amount of enzyme needed and Can be broken by mild concentration of enzyme.
Explanation:
Weak bonds like hydrogen bonds are found to beneficial in some situations. During the duplication of chromosomes which occurs in S phase of cell cycle the DNA replicated. This replication is facilitated by separation of the two strands of DNA and formation of complimentary strand on the two primary strands. The enzymes involved in the process of separation of strands are DNA helicase and Topoisomerase mainly. As the bonds between the strands are weak hydrogen bonds, the enzymes function effectively without requiring extra heat or more saturation. It will found to be difficult if those bonds will be covalent bonds because they are much stronger than hydrogen bonds and are not easily broken by these enzymes. Extra processes will be required to break those strong bonds.
