Question
DNA binding proteins interact with DNA to regulate gene expression. What sort of chemical bond between the protein and the DNA would be well suited for this type of interaction (think about strong bonds and weak bonds)? Explain. Type of bond: Explanation: Below is an example of a hydrogen bond situation. Label the partially positive dipole ( delta+) and the partially negative dipole (d-) on the appropriate atoms below. Then indicate the H-bond by a dashed line between the participating atoms. Which pairs of compounds below can participate in hydrogen bonding? Indicate the H-bond by a dashed line between the participating atoms.Explanation / Answer
3. there are two types of bonding in DNA- strong(Hydrogen Bonding). It is present in between the two sugar molecules.It binds the two sugar bases.
Weak(vander waal forces) present in between the two strands.
Both the forces hepls the DNA to be in shape, interact with each other and regulate the genes.
4. question not completely mention
5. Hydrogen bonding is present between a hydrogen atom and an electronegative element like oxygen, nitrogen. It is a strong bond which holds the two molecule. In the above question, 1 and 2 will form a hydrogen bonding as they meet the primary condition necessary for hydrogen bonding. In case of1, hydrogen bond will form between O and H and in 2, hydrogen bonding is formed between N and H.
