Front

What is the process by which muscle cells and nerve cells develop from the same fertilized egg?

Back

Differentiation

Front

What is CRISPR-Cas9 used for in genetic modification?

Back

It edits parts of the genome by adding, removing, or modifying sections of the DNA sequence.

Front

How can scientists control gene expression using CRISPR-Cas9?

Back

By activating or deactivating specific genes.

Front

What are the initial steps in gene expression?

Back

Double-stranded DNA unwinds into two strands.

Front

What is the process and product represented when DNA is transcribed?

Back

Process: Transcription; Product: mRNA.

Front

Why do muscle cells and nerve cells have the same DNA sequences but look and perform differently?

Back

The proteins expressed in each cell are different.

Front

What environmental factor influenced the fur color of the Himalayan rabbit?

Back

Specific temperatures activated the genes for black hair.

Front

What is the role of transcription in gene expression?

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is the significance of gene expression in cellular differentiation?

Back

Gene expression determines the specific proteins produced in a cell, leading to different cell types.

Front

How does temperature affect gene expression in the Himalayan rabbit?

Back

Temperature can activate or deactivate specific genes, influencing traits like fur color.
