Gene Expression

​Gene Expression

B.6D: Recognize that gene expression is a regulated process​

A Regulated (controlled) process ​by which gene transcription and translation (protein synthesis) are controlled by various (many) factors.

These factors include hormones or environmental fators.​

​

​Gene Expression

​

Multiple Choice

What is gene expression?

• a regulated process

• an easy process

• a quick process

• a slow process

​Environmentalfactors, in this case temperature, is turning "on" or "off" of certin genes that code for fur color.

​

​Himalayan Rabbit

​

Multiple Choice

The Himalayan rabbit's habitat has cold, snowy winters and mild summers. The body is typically covered in white fur except for the nose, feet, tail, and ears, which are covered in black fur.

A scientist shaved an area of white fur on the back of a Himalayan rabbit and placed an ice pack over the shaved area . The shaved area grew black fur.

Which of these best explains why the hair that grew back where the Ice pack was placed was black and not white?

• The white hair mutated to black hair as the rabbit's body temperature decreased.

• The coat color changed from white to black with the age of the rabbit.

• The genes for black hair were activated by specific temperatures.

• White hair only grows during certain times of the year.

Multiple Choice

CRISPR-Cas9 is a genetic modification technique that edits parts of the genome of an organism . Using this technique scientists can add, remove, or modify sections of the DNA sequence.

How can scientists use this technique to control gene expression?

• By determining the number of chromosomes in an organism

• By identifying how closely related one individual is to another

• By calculating the number of genes different organisms produce

• By activating or deactivating specific genes
