Answer:
<u>b. synthesizes new DNA only in the 5' to 3' direction.</u>
Explanation:
DNA Polymerase III is involved in replication of DNA, it is involved in the proofreading of the replication mistakes by activity reading 3' to 5' and synthesizing 5' to 3' . It can add nucleotides to the strand at the rate of about 1000 nucleotides per second.
Answer:
because existing cells divide to produce new cells
It protects the Earth from becoming over heated, but with pollution, global warming has become more apparent because of the destruction of the ozone layer
The effect of a catalyst is to increase the speed of the reaction, this is the speed at which reactants, A and B, are consumed, ant the product, C, is produced.
Given that when C is produced the solution bubbles, the bubbles are an indication of progression of the reaction.
The greater the speed of reaction, the earlier the reaction will end and the earlier the bubbles will stop.
So the student can identify the catalyst because the bubbles will stop first.
Answer: <span>The test tube that stops bubbling first contains the catalyst.</span>
