Little confused on the question but if I am suppose to match the question with one of the statements I would choose that
“The cell membrane pinches in to form two new cells.” - what happens during cytokinesis.
Answer:
D) with the phosphodiester backbone and with bases via the minor groove
Explanation:
The double helix is a fairly rigid and viscous molecule of immense length and a small diameter. In this molecule a major groove and a minor groove can be observed.
The major groove is deep and wide, the minor groove is shallow and narrow.
DNA-protein interactions are essential processes in cell life (activation or repression of transcription, DNA replication and repair).
Proteins bind to the inner part of the DNA grooves, through specific junctions: hydrogen bonds, and non-specific junctions: van der Waals interactions, and other general electrostatic interactions.
The proteins recognize donors and acceptors of hydrogen bonds, methyl groups (hydrophobic), the latter exclusive of the major groove; There are four possible patterns of recognition in the major groove, and only two in the minor groove (see figures).
Some proteins bind to DNA through the major groove, some others through the minor groove, and some need to bind to both, but the nucleosome form hydrogen bonds via the minor groove with the phophodiester backbone.
Thymine is replaced by the base Uracil
Answer:
Plant cells will be unable to perform glycolysis due to the inhibitor and will die.
Explanation:
Glucose is a high energy stable compound.Therefore in order to extract the stored energy for cellular use, it must be broken down. The addition of inorganic Phosphate ions(Pi) to 6-carbon glucose compound in the presence of 2ATP molecules is called Phosphorylation. This phosphorylation reaction is catalyse by Hexokinase.
The 6C-glucose is spitted to 6C-Fructose phosphate, and to 6C-fructose biphophate. The later is converted to 2molecules of 3Carbon compounds called triose phosphate.
It is during the conversion of 2-molecules of 3C- triphosphate to Pyruvate that yields 2 ATPs per molecule of glucose.
Therefore if hexokinase is inhibited , then the glucose phosphorylation can not occur. Hence the sequence of events as Glycolytic pathways that leads to production of ATP during formation of Pyruvate can not occur.
Definitely, plant cells biochemical reactions will seize, glycolytic pathways will be inhibited, ATPs will not be synthesized,leading to plant cells deaths.
