How many reactions can each type of enzyme catalyse?

One, and that is the Beauty of Life. In a laboratory a chemist is super-happy to obtain a 60% yield in a reaction - means 40% waste-product. Any Cell, with its thousands of chemical reactions occurring constantly and simultaneously, would IMMEDIATELY BOG-DOWN in useless by-products unless the YIELD of each and every ENZYME was not 100%.


What population would least likely to survive in a change in its ecosystem?

B. koalas that eat only eucalyptus leaves done


Example of eukarote?

Eukarote is a lifeform wherein reproduction does need mutation to "rapidly" change the "genetic" structure;therefore, changes take much longer to occur.. As a result, bacteria et cie can change almost on the hour.. for a human to change, it takes at least a generation.


How does transcription differ from DNA replication Describe at least four differences?

DNA replication produces a complimentary DNA strand. Transcription produces a complimentary mRNA strand. The major enzyme that carries out DNA replication is DNA Polymerase III (in prokaryotes). The major enzyme that carries out transcription is RNA Polymerase. DNA replication results in two copies of the DNA. Transciption does not affect the DNA - it simply re-anneals (re-joins) after the process. In DNA replication the complementary base to A is T. In transcription the complementary base to A is U.
