Mutations are random spontaneous changes that occur suddenly in the DNA. A single mutation can have a large effect, however in may cases evolutionary changes are based on the accumulation of many mutations. The gene flow is any movement of genes from one generation to another and is an important source of mutation

Now can you predict nucleotide quantities in a hypothetical scenario with more than four different types of nucleotides? An alie
den301095 [7]

Answer:

16% is G

12% is T

12%is A

22% is X

Explanation:

Given that each nucleotide is complimentary to another nucleotide, there cannot be more of one than the other. For example, C bonds to G, so there cannot be more C than G, because there would be nothing for it to bond to.

So if there is approximately 16% of the genome composed of C, that would mean that approximately 16% is composed of G (for it to bond to).

The same logic can be used to determine the amount of nucleotide X is present. If Y binds to X, and approximately 22% is composed of nucleotide Y, then the same percentage can be given to nucleotide X, and say the amount of X is 22%.

Now all of the nucleotides have to add up to 100%, so:

A + T + G + C + X + Y = 100%

A + T + (16%) + (16%) + (22%) + (22%) = 100%

A + T = 24%

Given that A binds to T, they must be equal to each other, hence we can say that the concentration of A, equals the concentration of T.

Therefore, the concentration of A is 12%, and the concentration of T is also 12%.

How is a terrarium similar to a natural ecosystem? how is it different?
inessss [21]

Answer:Terrarium is actually an artificially made greenhouse glass container where sunlight easily passes through and we give other necessary objects for the plant growth inside the glass container. And our earth is very similar to the terrarium, our mother nature gives all the necessary objects for plant growth. A terrarium is different however, because in a terrarium there are glass walls that collect the moisture and let it drop back down in smaller quantities.
