<h2>
Answer</h2>
The right option is (A).
<h2>
Explanation</h2>
The RNA gets its information from DNA to synthesise the proteins. It is different from DNA also due to the difference in one nitrogen basis as uracil. The thymine, the nitrogen basis that is only present in DNA is replaced with uracil to form RNA coding. The uracil also contains the same features as thymine has in DNA strains. Uracil makes a double H-bond with the adenine but does not contain CH4 group which is present in thymine.
Answer:
Explanation:
Gene expression is a tightly regulated process that allows a cell to respond to its changing environment. It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.
Answer:
30, 000 plaques.
Explanation:
Plaques may be defined as the clear zones or spots that indicates the lysis of the bacteriophages. These plaques are useful to count the number of progeny phages.
The formula used to calculate the phage is as follows;
Plaques progeny = [Number of plaques observe/(Dilution factor x Volume of diluted virus)]
Since, in the given question the dilution factor and volume is not given and it can be taken as unity.
Plaques progeny = 30, 000 / ( 1 x 1)
Plaques progeny = 30, 000.
Thus, the answer is 30, 000.
