G0 phase cells
The mitotic cycle of somatic, or body, cells is responsible for the production of copies of those cells. The mitotic cycle has different phases, each of which involves a different set of physiological changes to the cell. The G0 phase is described as the resting phase of a cell, where no activities relating to cell division are taking place. G0 phase cells remain in this phase their entire lives, so they do not divide. Another example of such a cell is found in red blood cells.
Curare will bind to the receptor but it doesn't cause the ion to flow inside. This will prevent the person from sent signal to the muscle. When the person trying to move the muscle, curare will also prevent acetylcholine to bind so there will be no muscle contractions. The symptoms would be paralyzed of muscle that uses ach receptor.
Answer:
B. a sequence of DNA bases that duplicates a sequence of RNA bases.
Explanation:
Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule.
Answer:
Hemoglobin is an iron-containing protein present in the blood that functions for transportation of oxygen to different body cells..
Each hemoglobin molecule have tetrahedral structure consist of four heme groups surrounded by a globin group. Heme, is composed of porphyrin (ringlike organic structure) which is attched to an iron atom. There are four iron atoms in each molecule of hemoglobin that binds with four oxygen atoms and globin carry two linked pair of polypeptide chain.
The oxygen reversibly binds with the polypeptide chain and the process called oxygenation.
