- Why is it important that [transcription factor] – [DNA] interactions are based on noncovalent bonds?
Homework Answers
The interactions between the DNA and transcription factors are non-covalent and specific so that they can perform necessary functions which is meant to be. At the same time, once the necessary functions gets over, the interactions that are merely non-covalent gets degraded so that the molecules [DNA and transcription factors] can provide additional functions that are necessary for the cell. The interactions between the DNA and proteins are transient, hence need to be non-covalent [requires less energy to break] and at the same time non-specific. Cell has evolved in such a way that, it carries out functions in the cell at minimal expense of energy.

Certain laboratories often need to prepare DNA duplexes for transcription factor binding assays. The DNA is purchased as single-stranded polynucleotides and hybridize them to form our duplexes, but this almost always leaves behind some un-renatured, single-stranded DNA, in the solution. How would you go about removing the single-stranded DNA fromour duplexes?

Hydrogen bonds are noncovalent interactions between a hydrogen atom with a partial positive charge, called the hydrogen bond donor, and an atom with a partial negative charge, called the hydrogen bond acceptor. Progesterone is a hormone that contains two ketone groups. The oxygen in the ketone group can function as a hydrogen bond acceptor. н, со CH, Select the amino acids that have side chains that can form a hydrogen bond with progesterone at pH 7. tryptophan...
