The linear sequence of the base pairs provides the code for genes and ultimately proteins. count(base) is actually implemented in C and runs very much faster than loops in Python. 6 ng/µL is also 0. If the moleculeconsists ofonelongpolynucleo-. Web tool (software) provides comprehensive facilities for designing for most PCR applications including standard, multiplex, long distance, late-pcr, inverse, real-time, unique, group-specific, bisulphite modification assays, overlap extension PCR (OE-PCR) multi-fragments assembling; the design oligonucleotide sets for long sequence assembly by ligase chain reaction (LCR) and in silico. European Molecular Biology Laboratory. Conversion DNA - protein. Now, push "Calculate" in "Calculation of the molar concentration". The gel is usually made from agarose, a polysaccharide that when heated in a buffer solution forms a semi-solid, slightly porous gel. The concentration of DNA can be estimated by running it on an agarose gel. Answer 2: If you know how many base pairs a DNA molecule has, then you can calculate the length - so I hope you like to do some math!. Molecular weight is a measure of the sum of the atomic weight values of the atoms in a molecule. Addition of 159. Thus, the size in base pair length of a DNA fragment can be calculated using the distance the fragment travels through the gel. Calculate the weight in grams of a double-helical DNA molecule stretching from the Earth to the moon (~320,000 km). Assume the phosphate group carries a sodium (Na+) counter-ion. edit: I have found references to masses of DNA with salt bound giving an average mass for a base-pair at roughly 660, so perhaps that's where your number comes. For simplicity's sake, base-pair length is substituted for molecular weight. , as well as an intramol. coli DNA molecule. Question: Calculate the molecular weight of a single-stranded DNA molecule that contains 25 nucleotides (an oligonucleotide). Figure out 1) how many picomoles are 1 microgram of the plasmid?. In the above 100,000-fold amplification example, if the targeted amplicon were to be 500 bp in length, the estimated molecular-weight of duplex DNA of 500bp is 325,000 g/mol (based an average base-pair having a molecular mass of 650 g/mol).
