Biology Keystone Module 2

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 meiosis?

Back

Meiosis is a specialized form of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.

Front

What is the main difference between mitosis and meiosis?

Back

Mitosis produces genetically identical daughter cells, while meiosis produces genetically diverse gametes.

Front

What is DNA transcription?

Back

DNA transcription is the process of copying a segment of DNA into messenger RNA (mRNA) for protein synthesis.

Front

What is DNA translation?

Back

DNA translation is the process by which ribosomes synthesize proteins using the information encoded in mRNA.

Front

What role do ribosomes play in protein synthesis?

Back

Ribosomes are the cellular structures that facilitate the translation of mRNA into a polypeptide chain (protein).

Front

What is geographic isolation?

Back

Geographic isolation occurs when a physical barrier separates populations, leading to reduced gene flow and potential speciation.

Front

What is behavioral isolation?

Back

Behavioral isolation is a form of reproductive isolation where two populations develop different mating behaviors, preventing interbreeding.

Front

What is the cell cycle?

Back

The cell cycle is a series of events that take place in a cell leading to its division and duplication, including interphase and mitotic phase.

Front

What are chromosomes?

Back

Chromosomes are long strands of DNA wrapped around proteins, containing the genetic information of an organism.
