A) The enzyme works faster, that is my own answer is on my mind
Answer:
Macro-molecules are used in the body after the conversion of micro-molecules.
Explanation:
Macro-molecules such as protein, carbohydrates and fats etc are bigger in size which can not be absorbed by the cell of the body so these Macro-molecules first broken down into micro-molecules such as amino acids, glucose and fatty acids etc. Protein is converted into amino acids, carbohydrates is converted into glucose and fats is converted into fatty acids by the action of different enzymes. These micro-molecules are used by the cell in order to generate energy.
Answer:
Option A and Option B
Explanation:
A transcription bubble is defined as a molecular structure which is formed when only a few or very limited section of the DNA strand has unwind-ed.
These transcription bubbles are small in size and in general their size ranges between 12-14 base pairs
An RNA polymerase which is about 9 nt long is responsible for making the DNA sequence ready for producing transcript at the 5' end (a complementary, antiparallel RNA strand )
Rate at which double stranded DNA molecule slide back and forth for transcription ranges with in 40-50 nt/sec
Hence, both option A and B are correct
