Biology Sem. 1

Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is an Autotroph?

Back

An autotroph is an organism that produces its own food from inorganic substances, typically through photosynthesis or chemosynthesis.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is the significance of the separation of sister chromatids?

Back

The separation of sister chromatids is crucial for ensuring that each daughter cell receives an identical set of chromosomes during cell division.

Front

How many chromosomes do fruit fly daughter cells have after mitosis?

Back

Fruit fly daughter cells have 8 chromosomes after mitosis, the same number as the parent cell.

Front

What is the Cell Cycle?

Back

The cell cycle is the series of phases that a cell goes through from its formation until it divides into two daughter cells.

Front

What is the difference between Mitosis and Meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is Crossing Over?

Back

Crossing over is a process during meiosis where homologous chromosomes exchange genetic material, increasing genetic diversity.

Front

What is Independent Assortment?

Back

Independent assortment is the random distribution of maternal and paternal chromosomes into gametes during meiosis.

Front

What is the role of the Mitotic Spindle?

Back

The mitotic spindle is a structure made of microtubules that segregates chromosomes into the daughter cells during mitosis.
