When DNA ligase has compelted its job catalyzing the formation of a phosphodiester bond to bring together the backbone of two separate DNA strands and bind them together, the result is that two separate strands of DNA become one.
It was very bright.
It was quite hot.
It was not so big.
It was 2 million yrs old.
It was made of electrons and neutrons.

Cell membrane allows some material to pass through it while on the same time it blocks other material from entering through it
Answer/Explanation:
The DNA in all living organisms is made up of 4 bases, adenine, thymine, guanine, cytosine. The RNA replaces thymine with uracil, making 5 types of nucleotide. The number of nucleotide pairs in a genome can range from half a million up to 100,000 million - meaning there are an exponential number of combinations of these 4 bases.
Imagine an organism exists that has only 2 nucleotides (<u><em>this is over 200,000x smaller than even the smallest bacterial genome</em></u>). If we allow any nucleotide at each of the 2 positions, then we have 4x4 (4²) or 16 possible combinations of sequences. For a nucleotide length of 4, the total number of possible combinations are 4⁴ or 256.
Since we are dealing with many millions of nucleotides, there are essentially infinite combinations of nucleotides, giving rise to the variation that produces over 20 million organisms on the planet.
