Re: Chromosome Differences

... single DNA molecules complexed with proteins. Each chromosome is replicated and then the chromosomes separate as a collection of different DNA strands during cell division, all without combining into a single DNA strand. Your genes are scattered about these different DNA molecules.

Re: Totipotent Stem Cell From Molecular Components

... saying that for a particular protein in my stem cell at least, the amount of that particular protein is the average of 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 ...

Help: Confused with primers in a PCR of a vector?

... to just determine the directionality of our insert. Because later in the lab, we did a whole bunch of sequence alignments with our gene (of both strands) and BLASTed it. But...I am just not really sure if I've done the PCR reactions correctly. Any help would be greatly appreciated. Thanks!

Re: mRNA Search for RT-PCR (U to T)

If we design primers to one strand out of two strands of cDNA then there is a chance that one of the primer will not be complementary to mRNA and it will not bind to mRNA.How can we synthesize cDNA from that mRNA?

DNA helix and gene

... other, so one gene sequence can be found on one strand and the second gene sequence on another (read in the opposite direction). However, both strands are required for transcription to mRNA since it's the complement strand that is used as template for it...
