An mRNA macromolecule transcribes genetic codes from a DNA macromolecule in a cell's nucleus and carries the code into the cytoplasm to synthesize a protein. Which of the following statements is true about the nucleotides in the mRNA macromolecule and the DNA macromolecules?
1. The number of uracil bases in the mRNA is the same as the number of cytosine bases on the strand of DNA that it transcribed.
2. The number of uracil bases in the mRNA is the same as the number of thymine bases on the strand of DNA that it transcribed.
3. The number of uracil bases in the mRNA is the same as the number of adenine bases on the strand of DNA that it transcribed.
4. The number of uracil bases in the mRNA is the same as the number of guanine bases on the strand of DNA that it transcribed.

Getting rid of my account might as well do it with some fun make sure to read all of this it is hilarious a plane was about to crash and there were 5 people on board and only 4 parachutes. the first person said: " i am roy keane, one of the best footballers in ireland. i am worth a lot of money and my fans need me so i think i should be saved." the others agreed and gave him one of the parachutes and off he went. the second person said: "i am gerry adams, a radical irish politician who can really my country and i think i should be saved." the others said: "o. k.", and gave him a parachute. the third person said: "i am george bush, president of the most powerful country in the world. everyone knows i am a really nice guy and everyone thinks i am stupid, but i'm not, so i am taking a parachute." and off he went. there were two people left, the pope and a 10 year old schoolgirl. the pope said: "child, i am old and frail and have lived my life while you are young, with everything before you. you take the parachute and i will stay with the aircraft and take my chance." "it's o. k." said the girl, "there are still two bush picked up my schoolbag."

The endoplasmic reticulum (er) is an organelle in some cells. in these cells, it is continuous with the nuclear membrane and forms a large part of the cell\'s total membrane. sort the phrases below as describing rough er, smooth er, both, or neither. note: if you answer any part of this question incorrectly, a single red x will appear indicating that one or more of the phrases are sorted incorrectly.1) found in prokaryites and uekaryotys2) involved in protein synthesis3) involve in lipid synthesis4) contains molecular chaperones in lumen5) bound with ribosomes6) involved in toxin or drug metabolism7) large systemot internnected tubules, vesicles, and sacs8) "packages" enzymes in vesicles for secretion.
