Gene Regulation

The two different cells become mutated

The proteins expressed in each cell are different

They actually have different DNA in the two types of cells.

The genome of the different cells changes

DNA

nucleus

ribosomes

plasma membrane

all sections of DNA are activated to determine the structure of a body cell

ONLY ONE section of DNA are deactivated to determine the structure of a body cell

only specific sections of DNA sequence are activated to determine the structure and functions of a body cell

Pigments change color when the rabbit is shaved.

DNA mutates when exposed to cold temperatures.

Gene expression only occurs in cold temperatures

Temperature can affect how genes are expressed.

The alleles for fur color change as the fox grows older.

The color is affected by the latitude of the animal.

The color of the foxes are determined at birth.

The genes that determine color is affected by temperature.

Genes are regulated through mutations that occur.

External and Internal factors can affect which genes a cell expresses.

Genes can only be regulated by changing the DNA sequence.

None of these

The mutation of DNA to create specialized cells

The turning on and off of genes by environmental factors

The transforming of stem cells into specialized cells

All of these

Operons

Homeobox Genes

Transcription Factors

Temperature

a) By modifying DNA sequences

b) By altering how a gene is expressed.

c) By directly changing gene function

d) None of the above
