DNA together with RNA are the most important molecules in biology. It is the hereditary material in humans and almost all other organisms in our planet. Most DNA is found in the nucleus and some or small portion can be found in the mitochondria.
The main features of the three-dimentional structure of DNA are:
DNA is double-stranded composing of two polynucleotide strands alongside each other which are wound round each other to form a double helix. The two strands are joined together by hydrogen bonds between the bases and these bases form base pairs which is like a rung of a ladder. The base pairs are specific. Base pair A only binds to T (T with A), and C only binds to G (G with C). These are called complementary base pairs. As a wholes, DNA molecules control the production of proteins which characterize each type of organism.
Answer: a crack forms, magma pushes upward, rock moves outward, magma hardens.
I know this 100% fact
Explanation:
Answer:
I would say B.
Explanation:
A would only fix biodiversity temporarily, until humans come and wipe them out again. C is just kind of impossible, and containing them could also be problematic. D is also unreasonable, and some animals would not be able to thrive in new ecosystems. B would help save the environment, which would save the animals, which would help biodiversity.
Answer:
Explanation:
The formation of a gas is a clue to chemical changes. The bubbles of gas that you observed form when an antacid is dropped into water is an example of change. ... After ice melts into liquid water, you can refreeze it into solid ice if the temperature drops. Freezing and melting are physical changes.
Answer:
Fructose 1,6-bisphosphatase, on the other hand, is inhibited by AMP and activated by citrate. A high level of AMP indicates that the energy charge is low and signals the need for ATP generation.
