What is cell differentiation?

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type, leading to the development of specific cell types with distinct functions.

Front

What is the complementary DNA strand to TTCGAC?

Back

AAGCTG

Front

What happens when cells do not follow the cell cycle properly?

Back

They may become cancer cells, grow abnormally, and form tumors.

Front

What is transcription in genetics?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which carries the genetic information to the ribosome for protein synthesis.

Front

What is translation in genetics?

Back

Translation is the process by which ribosomes synthesize proteins using the mRNA sequence as a template.

Front

Define cancer cells.

Back

Cancer cells are abnormal cells that divide uncontrollably and can invade other tissues, often leading to the formation of tumors.

Front

What is the role of mRNA?

Back

mRNA (messenger RNA) serves as a template for protein synthesis, carrying genetic information from DNA to the ribosome.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for cell growth, replication, and division, ensuring proper development and maintenance of tissues.

Front

What is a tumor?

Back

A tumor is a mass of tissue formed by an accumulation of abnormal cells, which can be benign (non-cancerous) or malignant (cancerous).

Front

What is the difference between DNA and RNA?

Back

DNA (deoxyribonucleic acid) stores genetic information, while RNA (ribonucleic acid) plays a role in translating that information into proteins.
