The condition that is most likely to be present in the region left by the melting glaciers in Alaska is that algae and fungi growing on bare rock. This is because environment in primary succession is essentially deprived of vegetation and several kinds of organisms. Thus, plants are unable to grow since the soil lacks nutrients.
Independent of the conditions of the outside of the cell
The study of chemical reactions of living this is called biochemistry.
DNA ligase is an enzyme that repairs irregularities or breaks in the backbone of double-stranded DNA molecules. It has important role in the process of DNA replication and DNA repair. It has three general functions: It seals repairs in the DNA, it seals recombination fragments, and it connects Okazaki fragments (small DNA fragments formed during the replication of double-stranded DNA). DNA ligase functions by forming a bond between the end of a “donor” nucleotide and the end of an “acceptor” nucleotide.
