Re: Totipotent Stem Cell From Molecular Components

... the gene expression in # of strands of mRNA * 100. I am getting the protein this way. I take the results of PCR and put it in a test tube with RNA polymerases, Ribosomes, and other proteins that help with protein synthesis. I then look at the structure of the protein as is and inside a cell(every ...

A question regarding PCR

... is how many base pairs the amplified product will have, but it's not clear to me how to answer it. When the two DNA strand separate and have polymerases amplifying them, won't the initial products have different lengths since there is this little acatttg sequence before the first primer position? ...

Why is ATP rather than GTP, CTP or TTP the energy currency?

... soon as ATP was being used/produced a bit more than the others, a feedback loop set in, and it became dominant. Obviously, all 4 are used by DNA polymerases, and GTP is used by numerous receptor proteins. I'm not aware of much use for TTP or CTP, but GTP is prominent. So, as JackBean said: "(hint ...

Re: question for evolutionary biologist.

... This process starts with Transcription. This is the first step in decoding a cell's genetic information. During transcription, Enzymes called RNA polymerases build RNA molecules that are complementary to a portion of one strand of the DNA double helix. Now what is an enzyme? Guess what? It is ...

Help please with viruses?

... in its capsid? Does the capsid contain any enzymes? How does the virus enter the host cell? How is its genome replicated? Does it encode its own polymerases? Which ones? Where does it replicate its genome? Where is the virus assembled? How does it get out of the cell? How does it get to the kidneys? ...
