What is Transcription?

Back

Transcription is the process of copying a segment of DNA into RNA. It occurs in the nucleus and is the first step in gene expression.

Front

What happens during Prophase in cell division?

Back

During Prophase, the nuclear membrane disappears, chromosomes condense and become visible, and spindle fibers begin to form.

Front

What is the Anaphase phase of the cell cycle?

Back

Anaphase is the stage in mitosis where sister chromatids are pulled apart to opposite ends of the cell.

Front

What is the complementary DNA strand for AGC CAT GTA TAC?

Back

The complementary DNA strand is TCG GTA CAT ATG.

Front

What is Protein Synthesis?

Back

Protein synthesis is the process by which cells build proteins based on the instructions encoded in DNA. It involves transcription and translation.

Front

What is the role of Ribosomes in a cell?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the difference between DNA Replication and Transcription?

Back

DNA Replication copies the entire DNA molecule, while Transcription only copies a specific gene into RNA.

Front

What occurs during Metaphase?

Back

During Metaphase, chromosomes align at the cell's equatorial plane and attach to spindle fibers.

Front

What is the function of Spindle Fibers?

Back

Spindle fibers are structures that help separate chromosomes during cell division by pulling them to opposite poles of the cell.

Front

What is the significance of the Nuclear Membrane?

Back

The nuclear membrane protects the nucleus and regulates the passage of materials in and out of the nucleus.
