The regulation of the cell cycle. Introduction: The cell cycle is classified as the interphase and the mitotic phase. Interphase is the longest period of the cell cycle. In this phase, cell growth, DNA (deoxyribonucleic acid) replication and preparation for cell division occur. This stage is further divided in G 1, S and G 2 phase. G 1 phase or the first gap phase is the period between the last cell division and the DNA synthesis for the next cell division. The cell actively grows in this phase. S phase, also known as the synthesis phase, is the phase where the DNA is replicated. G 2 phase or the second gap phase is when the cell prepares for cell division. Further growth occurs in this phase. The mitotic phase is shorter and contains two subphases, namely mitosis, and cytokinesis. During mitosis, the replicated DNA divides equally into two nuclei. In the cytokinesis, the cytoplasm finally divides in order to form two new daughter cells.

Summary Introduction

To review:

The regulation of the cell cycle.

Introduction:

The cell cycle is classified as the interphase and the mitotic phase. Interphase is the longest period of the cell cycle. In this phase, cell growth, DNA (deoxyribonucleic acid) replication and preparation for cell division occur. This stage is further divided in G_1, S and G₂ phase. G₁ phase or the first gap phase is the period between the last cell division and the DNA synthesis for the next cell division. The cell actively grows in this phase. S phase, also known as the synthesis phase, is the phase where the DNA is replicated. G₂ phase or the second gap phase is when the cell prepares for cell division. Further growth occurs in this phase.

The mitotic phase is shorter and contains two subphases, namely mitosis, and cytokinesis. During mitosis, the replicated DNA divides equally into two nuclei. In the cytokinesis, the cytoplasm finally divides in order to form two new daughter cells.

In as much detail as possible, hand draw a schematic diagram of the hypothalamic-pituitary- gonad (HPG) axis in the human male. Be sure to include all the relevant structures and hormones. You must define all abbreviations the first time you use them. Please include (and explain) the feedback loops.

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth. Did a patient relationship with the transfusing hospital exist?
