Proteins are essential molecules that perform many functions within cells. A diagram of protein synthesis is shown below.
Based on the image, the structure A is , and its function is to .
Structure B is a , and its function is to .
Location of transcription
Transcribe DNA to mRNA
Translate mRNA to an amino acid sequence
Insulin is a hormone that is produced in the pancreas. Insulin functions as a key to allow glucose (sugar) from the bloodstream to enter the cells. Glucose provides the body with the energy needed to function properly. Without insulin, glucose in the blood stream will build up in the blood leading to high blood sugar levels. People with diabetes do not produce their own insulin.
What factor is most responsible for the lack of insulin in people with diabetes?
Internal factors
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?
How do external and internal factors affect the traits that an organism exhibits?
Look back and Himalayan rabbit item that connects to gene expression and production of proteins.
