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

n species was discovered that has DNA comprised of 6 different bases: G binds to C; A binds to T: and X binds to Y. Approximately 16% of this alien genome is comprised of nucleotides containing C, and 22% is comprised of nucleotides containing Y. Given this information, calculate the percentage of the alien genome that is comprised of nucleotides containing G, T, A, and X. (a) _____% of the alien genome is comprised of G. (b) _____% of the alien genome is comprised of T. (c) _____% of the alien genome is comprised of A. (d) _____% of the alien genome is comprised of X.

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 land breeze similar to a sea breeze? How do the differ?
Pavel [41]
<span>Sea breezes and land breezes are similar in that they are both created by changes in temperature near the ground. With a sea breeze, the air over land warms (during daytime), pressure drops, and air accelerates from sea to land in response. With a land breeze, the air over land cools (during nighttime), pressure rises, and air accelerates from land to sea in response.</span>

How does an organisms growth compared to the growth of an icicle
Travka [436]

Answer:

An icicle grows as water drips down the structure and freezes adding to its length and thickness. Organisms grow via the addition of new cells to the organs it contains. These organs grow from the inside out over the entire structure.

Y’all help meeeee
OLEGan [10]

Answer:

C. Balancing a chemical equation simply means ensuring that the same numbers of atoms of the elements which are involved in the reaction (reactants) are represented in the result of the reaction (products). This demonstrates that matter is not created nor destroyed in a chemical reaction.

Explanation:

The products of a reaction contains a certain number of each atom constituting each product;

Matter cannot be created or destroyed so the reactants must contain the same number of each atom;

Balancing the equations means this will be the case and hence, this will demonstrate the number of each reactant atom/molecule necessary for the reaction to proceed
