A biochemist isolated and purified molecules needed for dna replication. Whne she added some dna, replictation occursd but the d
na molecules were defective. Each consisted of a normal dna strand paired with numerous segments of dna a few hundred nucleotides long. What had she probably left out of the mixture?
DNA replication is the process of formation of new molecules of DNA from the existing one. This process occurs in semiconservative way i.e each new strand consist of one newly synthesised strand and one old parent strand that act as template for the formation of new strand. replication on one strand occurs continuously from 5 prime to 3 prime but on other strands it occurs discontinuously from 5 prime to 3 prime because DNA polymerase moves only in one direction from 5 prime to 3 prime. Hence in discontinuous strands gaps remained. These gaps are filled by Ligase enzyme.
The term plankton comes from the Greek derivative planktos, meaning wandering. Organisms in this group spend either part or all of their life in a drifting state, with no ability to swim against a current. Most have little or no ability to swim at all. Though some are larger, most planktonic creatures are microscopic and make up the bottom of the food chain in aquatic environments
Plankton can be divided into two categories: phytoplankton are those organisms that are plant-like, and zooplankton are organisms that are animal-like. Interestingly enough, many planktonic species are neither plant nor animal but are creatures that belong to the kingdom Protista
Zebra muscles are found in water bodies which attached to pipes and other surfaces of water supply to impliment the availability of plankton
The answer is true as phenotype involves of having to see the organisms character and their morphological features, by this, it is trying to apply to both of the physical and psychological characteristics, making the sentence above as true.
