Answer:
<h2>
Transcription is defined as formation of messenger RNA (mRNA) from the DNA. Transcription occurs through RNA polymerase.</h2>
Explanation:
For transcription one strand serves as template and other strand works as coding strand. Coding strand is identical to the RNA strand forms after transcription using the template strand. Promoter gene base sequence will ultimately determines which DNA strand will serve as template strand for transcription. It also depends on where the genes are present which will be transcribed and ultimately forms the proteins.
Here are the answers:
1. WHAT YOU WILL BE LOOKING FOR AS EVIDENCE OF REACTION IN THIS EXPERIMET IS FORMATION OF OXYGEN BUBBLES.
This is because, the catalase enzyme on which this activity is based is an enzyme that speeds up the rate of decomposition of hydrogen peroxide in the cells, breaking it down to oxygen and water. Thus, when this reaction is taking place you will notice that bubbles will form in the test tube. These bubbles is the oxygen gas that is been given off. The presence of the bubbles indicate that the reaction is occurring.
2. YES, THE CATALASE ENZYME WAS PRESENT IN THE PLANT TISSUE THAT WAS TESTED.
The catalase enzyme is present in all plants. The plants need the enzyme to help them breakdown hydrogen peroxide into water and oxygen. This is because the hydrogen peroxide is very toxic to the plant cells and can destroy them, thus the hydrogen peroxide has to be broken down into water and oxygen immediately it is formed.
3. YES, THE CATALASE ENZYME WAS PRESENT IN THE ANIMAL TISSUE TESTED.
In animals, the catalase enzyme is found in great number in the liver. As a result of the metabolic reactions which occur in the liver, hydrogen peroxide is always produce in the liver. The hydrogen peroxide is very toxic to the liver cells and has to be getting rid of on an immediate basis. The catalase is the enzyme which breakdown the hydrogen peroxide into water and oxygen which are not toxic to the cells.
Answer:
Cobalt Co
Explanation:
Co and Zn can fully replace each other, except perhaps for small individual requirements that are met by minute metal concentrations supplied as contaminants.
