To test his hypothesis, the student will have to design an experiment to measure the effects of <u>temperature on cellular growth</u>.

To test the effects of temperature on cellular growth the student will have to create an experiment containing the there kinds of variables:

Dependent
Independent
Control

In this experiment, the control variable will be the kind of cells used, as well as the incubation methods being used. We identify these as the control variable given that they will remain constant.

The independent variable will be the Temperature at which we will place each cell being studied. The dependent variable, on the other hand, is by definition, what we seek to measure. In the case given it would correspond to the amount of cellular growth.

To test his theory of the effects of temperature on cellular growth, a student can design an experiment in which the control variable will be the cells themselves, the independent variable will be the Temperature, and the cellular growth can act as the dependent variable.

Answer:

Regulatory gene

Explanation:

Transcription is one of the major processes that occurs during gene expression. It is the transfer of the genetic instructions in DNA to mRNA. A strand of mRNA is made using complementary base pairs.

However, there is need for gene expression to be regulated.

Gene regulation refers to the mechanism that acts to induce or repress the expression of a gene. These include structural & chemical changes to the genetic material, binding of proteins to specific DNA elements to regulate transcription. These proteins that influences transcription by binding to specific nucleotide sequences (DNA segments/gene) are referred to as REGULATORY PROTEINS and those involved in regulating transcription of genes are called TRANSCRIPTION FACTORS.

Regulatory proteins controls the rate and manner of gene expression by binding to specific genes, thus, making it easy or hard for RNA polymerase (enzyme that attaches to DNA to synthesize mRNA molecule) to bind to the promoter of that gene.

Transcription factors (regulatory proteins) that promote gene transcription are called ACTIVATORS while those that decrease are called REPRESSORS.
