How far off are scientists from making a synthetic cell?
Is there any method to detect whether a protein is at all active (phosphorylated) using a tool such as an antibody that targets all or multiple phosphorylation sites?
I have an 8-year-old son bent on becoming a scientist. He is very bright but feels he can't make any mistakes and has to be right all of the time. Is there any way I can get a scientist to let him know it is okay not to be right all of the time, and that he has to accept that he will make mistakes before he can become a scientist?
I've learned how DNA contains instructions for building specific proteins, but what about the next step? In other words, how does the protein control what colour a person's hair will be, or how tall she will be? Also, how does the protein control how the body is constructed? Does it define that my kneebone is connected to my thighbone, or that my heart has four chambers? Thanks!
I have heard conflicting answers to the following question and wonder which is correct: If unesterified cholesterol were added into the bilayer membrane of human cells in increasing amounts, would the cell membranes become more stiff or less?
In my pharmacology class, I noticed that many generic drug names have words after the name (e.g., morphine sulfate and potassium bromide). I know the words are derived from the molecular structure of the drug, but I was wondering what they mean exactly. Is there a pharmacokinetic or pharmacodynamic significance (e.g., sulfates are minimally protein bound and chlorides have a short onset)? Can a drug have multiple forms (e.g., morphine sulfate and morphine phosphate)? Also, what is the name for this collective group of words?
During telophase, when new daughter cells form how do they "know" what type of cell they will become?
During mitosis, where do the organelles go as the process is occurring?
Why is it that a graph representing enzyme activity for pH is drawn in most textbooks as a perfect bell curve graph vs. a temperature graph, which tends to show a quicker denaturing of enzyme in small increments of temperature change? I would like to know what is happening to the enzyme at the molecular level.
Is a virus a living organism?
