Will make brainliest! explain why an mrna strand composed of only uracil nucleotides () did conclusively prove that the dna code was a triplet code.

mRNA composed of only uracil nucleotides did not conclusively prove that the DNA code was a triplet code because only a single amino acid would be produced from this code, regardless of whether or not the code was a singlet, doublet, triplet, or quartet code, since the only base in the sequence was a U. !

Plz mark brainliest! Have a awesome day!

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

you know that this symptom is misleading and quite often is related to: heart attack

a heart attack is a condition that occurs when the blood flow that transports oxygen to the heart muscle is damaged or cut off completely. the coronary arteries that supply the heart muscle with blood flow can be blocked by the accumulation of plaque. also, when the plaque within the heart artery breaks, it creates blood clot that can also hinder the blood flow. men that are over 45years of age and women that are over 55years of age are at risk of having a heart attack. the symptoms of a heart attack include chest discomfort, chest pain, coughing, and shortness of breath.
