Match each term with its definition.

1) a DNA sequence located near the start of a gene that RNA polymerase binds to initiate transcription
2) a regulatory protein that blocks transcription by binding to the operator site
3) a transcriptional element that blocks the signal between enhancers and promoters
4) a gene that controls the expression of one or more genes by promoting or inhibiting transcription
5) a small molecule that activates transcription by inhibiting the action of a repressor protein
6) a short DNA sequence that can be recognized by a repressor protein

a) insulator
b) operator
c) repressor
d) inducer
e) regulatory gene
f) promoter

The correct terms have been inserted before the description that matches it:

Promoter

1) a DNA sequence located near the start of a gene that RNA polymerase binds to initiate transcription

Repressor

2) a regulatory protein that blocks transcription by binding to the operator site

Insulator

3) a transcriptional element that blocks the signal between enhancers and promoters

Operator

4) a gene that controls the expression of one or more genes by promoting or inhibiting transcription

Inducer

5) a small molecule that activates transcription by inhibiting the action of a repressor protein

Regulatory Gene

6) a short DNA sequence that can be recognized by a repressor protein

Notice the difference between genes and proteins, it is by working together that the cell is able to control these functions. A defect in any of these could possibly prevent the normal functioning of the cell.

Hope that answers the question, have a great day!

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
