Summary Introduction

Introduction:

A cell spends most of its time in the interphase of the cell cycle. At the time of interphase, a cell copies its DNA to prepare for mitosis or meiosis. The cell organelles get double in number, and the process of protein synthesis occurs during interphase.The DNA is in uncoiled chromatin form in this stage. The interphase includes the first gap phase, the second gap phase, and the synthesis phase.

Answer to Problem 1PL

Correct answer:

The correct answer is option (a) cytokinesis.

Explanation of Solution

Explanation/justification for the correct answer:

Option (a) cytokinesis. The cytoplasm of a eukaryotic cell divides to form two daughter cells at the time of cytokinesis. The cytokinesis occurs during or after the nuclear division in meiosis and mitosis. The spindle apparatus separates and transports the replicated chromatids in the cytoplasm of dividing daughter cells. Cytokinesis is not a part of interphase. So, the correct answer is option (a).

Explanation for incorrect answer:

Option (b) first gap phase. The First gap phase is also known as Gap 1 phase. The cell synthesizes the protein and grows to double from its original size in this phase. At the first gap phase, the volume of cytoplasm rise, and organelles get replicated. The first gap phase is the first stage of interphase. So, this is an incorrect answer.

Option (c) second gap phase. The second gap phase is also called the Gap 2 phase. It is the third stage of interphase. The mitochondria start to divides, and the cell continues to grow until the process of mitosis begins in the second gap phase. The chloroplast of plants divides during the second gap phase. So, this is an incorrect answer.

Option (d) synthesis phase. The synthesis phase is part of interphase, where the synthesis of DNA occurs. The synthesis phase started when the cell cleared checkpoints of the first gap phase. The synthesis phase aims to replicate DNA, so that daughter cells get complete sets of chromosomes. So option (d) is incorrect.

Preoperative Diagnosis: Torn medial meniscus, left knee Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee. Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…
