NEET Important Questions for Cell Cycle and Cell Divisions

NEET (UG) which stands for the National Eligibility cum Entrance Test (Undergraduate) is a pre-medical entrance exam that is conducted for the students who want to opt for medical-related fields as future career prospects. Anyone who wants to pursue MBBS, BDS, BAMS, BHMS, BUMS, and other related courses have to appear for NEET as it is the only entrance exam for this particular field. NEET was formerly known as the All India Pre-Medical Test (AIPMT) and was later named NEET. The administration which looks after the swift conduct of NEET is the National Testing Agency. Earlier between the years 2013 to 2018, it was under the power of the Central Board of Secondary Education. However, from 2019 onwards, the National Testing Agency took the responsibility of conducting the exam ahead.

With a duration of 3 hours and 20 minutes, the exam of NEET happens once a year where there are around 72,000 seats for MBBS and BDS collectively active. NEET is considered to be one of the toughest entrance exams held in the country and hence it requires a good and precise sincerity in students, focusing with all their minds. The candidates should follow a strict timetable and be thorough with all the important questions from all the major portions of the respective curriculum. For scoring a decent score in NEET, only NCERT is not sufficient and different books and sample papers must also be referred to by them.

It is a must for candidates to be intimately thorough with the important questions as well as the most asked questions. There are indeed several questions that can be asked repeatedly because of their tricky nature or importance; hence, it is a must to go through them seriously.

Vedantu, on the other hand, provides a huge and detailed range of questions with regard to sample papers and worksheets which can be opted by NEET applicants and benefitted by them. Study and make a plan according to the weightage and keep moving ahead with the portions.

FAQs on NEET Cell Cycle and Cell Divisions Important Questions with Solutions

1. Explain the Cell Cycle.

Cell Cycle Consists of AND replication and cell division. All the processes and events that take place in the cell cycle are controlled genetically. The duration of the cell cycle varies in different organisms and it also depends on the type of cells. If we talk about the human cell cycle then in an average manner, a human cell cycle lasts up to 24 hours. The yeast cell cycle takes only ninety minutes to complete. The cell cycle is always divided into the M phase and Interphase. In interphase cell growth and replication of DNA takes place, interphase takes 95% time of the whole cell cycle. In the M phase, the cell division takes place known as Mitosis.

2. What is mitosis?

Mitosis generally happens in diploid somatic cells of beings ( animals ) though there are some exceptions like the haploid male drone of honey bees. If we talk about plants then mitosis takes place in both diploid and haploid cells. It is mitosis that is responsible for the genetic continuity, growth, and repair of multicellular organisms. Seeing this process in humans, we can state that the epithelial lining, lining of the gut and also the blood cells are replaced in a continuous manner. In the plants, it is meristematic tissues that divide continuously all their life.

Mitosis is accountable for asexual reproduction and vegetative reproduction. Karyokinesis occurs in 4 parts:

Prophase
Metaphase
Anaphase
Telophase

3. What do you understand by prophase, metaphase and anaphase?

We will discuss all three of them separately

Prophase

Chromosomes are not tangled but are condensed. The two chromatids attached to the centromere are visible in this process. All the duplicated centrosomes radiate asters ( microtubules ). Apparatus that is Mitotic consists of spindle fibres and also asters ( microtubule ). In this process, Golgi bodies, endoplasmic reticulum, etc disappear.

Metaphase

In this process, the complete disintegration of the nuclear force happens. The two sister chromatids are attached by the centromere that is attached by centromere which is aligned at the equator. Each chromatid is attracted to the spindle fibres.

Anaphase

In this phase, the centromere splits and the two sister chromatids separate and go to different poles.

4. What is cytokinesis?

In this process separation of cytoplasm happens. This separation takes place after the two nuclei are being formed. After this, the cell organelles are distributed between the daughter cells. In some beings like algae, fungi and plant cells, the process of cytokinesis is not immediately followed by karyokinesis. The stage followed by is known as a syncytium. Examples are liquid endosperm in coconut, coenocytic hyphae of Rhizopus, etc.

5. What is meant by Interphase?

Interphase is the process that takes between two successive M phases of the cell division. Interphase is divided into three phases:

GAP 1

This is the gap between mitosis and DNA replication of the next cycle of cell

Synthesis

DNA replication takes place in this process. The content of DNA cells doubles and duplication of centriole happens. Chromosome numbers remain the same.

GAP 2

The cells continue to grow and get prepared for mitosis. In this process protein synthesis also takes place.
