Q8. Which one of the following is not a part of a transcription unit in DNA?
Answer : Option A
Explaination / Solution:
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
Transcription of DNA requires a promoter, the structural gene to be transcripted and a terminator. The inducer is not required during transcription of DNA.
Q9. A small town with a demand of 800 kW of electric power at 220 V is situated 15 km away from an electric plant generating power at 440 V. The resistance of the two wire line carrying power is 0.5 Ω per km. The town gets power from the line through a 4000-220 V step-down transformer at a sub-station in the town. Power that the plant supply, assuming there is negligible power loss due to leakage is
Answer : Option A
Explaination / Solution:
Total electric power required, P = 800 kW
supply voltage V = 220 volt
voltage at which electric plant generating power V1 = 440 volt
distance between town and power generating station, d = 15 km
total resistance of two wire cable R = (15+15) x 0.5 = 15 ohm
input voltage of transformer Vi = 4000 volt
output voltage of transformer Vo = 220 volt
current in wire line
total power supplied by the plant = 800 + 600 = 1400 KW
Q10. Three voltmeters, all having different resistances, are joined as shown. When some potential difference is applied across A and B, their readings are V1, V2 , V3 .
Answer : Option D
Explaination / Solution:
V3 and combination of V1 and V2 (V1 + V2) are connected in parallel so potential in V3 must be equal to potential in (V1 + V2)
the potential difference across AB = = +.
