Students illustrate a flow-chart model of gene expression. How does genetic information flow in the cell? Complete the model by placing the labels into the boxes.
Genetic information is stored in DNA molecules.
Genetic information is used to assemble protein into DNA molecules.
Genetic information is carried by messenger molecules (RNA).
Genetic information is stored in protein molecules.
Genetic information is used to assemble amino acids into protein molecules.

which fault and or fold did you find most difficult to diagram

i guess because there isn't enough love going around. < 3

1. the geologists have established a set of principals that can can be used o determine the relative ages of rock. this principal is applied to sedimentary and volcanic rocks. the rocks exposed to wall of grand canyon has layers and by studying the number of horizontal layers in the rock(strata) the relative age can be determined. the layer first formed will appear at the bottom and the the layer of strata last formed appear at the top. by using this information the approximate age of rocks can be determined.

2. carbon dating is used to find the relative age of rock in numbers which means for the rocks that has age between 1-70,000 years.

3. for the rocks of age range between 1,000 - billion of years potassium-argon dating is used.
