The DNA is splitting in two, thymine pairs with adenine, and guanine pairs with cytosine
Answer:
mRNA
Explanation:
poly-deoxythymidine (poly-dT) beads binds to polyadenylated (poly (A) molecules with high affinity because Thymidine base pairs with the Adenine of the poly(A) chain.
Since messenger RNA (mRNA) is polyadenylated after transcription in contrast to other RNA species, this method is more suitable for mRNA purification.
Cellular respiration i believe
Zwitterion
Zwitterion also known as dipolar
ion refers to a substance that has at least one positive and one negative
electrical charge at different locations and the net charge of the entire
molecule is zero. Examples of zwitterions are amino acids.
I am pretty sure that biologists use molecular clocks to try to measure <span>when two species separated from a shared ancestor. Do hope you still need the anwer because this one is definitely correct, do not hasitate to use it! Regards.</span>
