Aresearcher creates random copolymers of three nucleotides by mixing polynucleotide phosphorylase with guanine and adenine nucleotides in a ratio of 5 guanine nucleotides to 1 adenine. which of the following three nucleotide copolymers would most likely be most abundant? a. ggg d. gaa e. aaa b. gag c. aga

The answer is A. GGG.

To calculate this, a multiplication rule is used. The multiplication rule calculates the probability that both of two events will occur. In this method, the possibilities of each event are multiplied.

If a ratio is 5 guanine to 1 adenine, this means that the possibility of adenine to be created is , and the possibility of guanine to be created is .

Now, we will use the multiplication rule to calculate the possibility of creation each of these 5 copolymers:
GGG -  ×  ×  = 0.58
GAA -   ×  ×  = 0.02
AAA -   ×  ×  = 0.005
GAG -   ×  ×  = 0.12
AGA -   ×  ×  = 0.02

According to this, the greatest possibility to be created has copolymer GGG.

An ecosystem is in a certain area and includes living and non living plus there is weather conditions and a biome is a large amount of area with similar climate.so ecosystem is based on weather and biome is based on the average climate
