- please help molecular biology technique RT-PCR that have been used to study the protein Epidermal growth factor receptor I need to following using 1 journal article. please provide the link in the end i will appreciate it. and provide the answer in 1-3 paragraph per each part part 1 Detail the technique used to study this protein. part 2 What were the results reported for the protein using this technique (clear understanding of the set of results.a.) Explain briefly how silica allows us to purify DNA. Be sure to state the relevant biochemical features of silica and DNA as well as any relevant reagents or steps that are important for the purification. Your answer should explain both how we get the DNA to bind in the first place, and how we are able to remove the DNA. You do not (and should not) explain earlier steps in a DNA purification; focus you answer on the silica:DNA interaction. b.) In theory, can a silica spin column also be used to purify RNA? If so, explain how (and why we did not observe RNA when analyzing plasmid DNA via agarose gel electrophoresis). If not, explain why not.Please ASAP. Thank you. Regarding the double helix of DNA, which of the following is true? a. Guanine pairs up with cytosine with three hydrogen bonds b. Complementary strands of DNA are held together by covalent bonds c.

- Preparing plasmid DNA (double stranded, circular) for Sanger sequencing involves annealing a complementary, single-stranded oligonucleotide DNA primer to one strand of the plasmid template. This is routinely accomplished by heating the plasmid DNA and primer to 90°C and then slowly bringing the temperature down to 25°C. Why does this protocol work? What enzyme is used and what other components are required in the sequencing reaction? How does the Sanger method determine the sequence?Preparing plasmid (double-stranded, circular) DNA for sequencing involves annealing a complementary, short, single stranded oligonucleotide DNA primer to one strand of the plasmid template. This is routinely accomplished by heating the plasmid DNA and primer to 90 °C and then slowly bringing the temperature down to 25 °C. Why does this protocol work?Which statements are true? Explain why or why not.1 Because the DNA double helix is only 2 nm wide—well below the limit of resolution of the light microscope—it is impossible to see chromosomes in living cells withoutspecial stains.2 A fluorescent molecule, having absorbed a singlephoton of light at one wavelength, always emits it at a longer wavelength.

PotassiumQuick help Only cell biology Which process is described in the following paragraph? During DNA synthesis, before the enzyme adds the next nucleotide to a growing DNA strand, it checks whether the previously added nucleotide is correctly base-paired to the template strand. If so, the polymerase adds the next nucleotide; if not, the polymerase clips off the mispaired nucleotide and tries again. This is carried out by cleaving the phosphodiester backbone using the enzyme’s 3’-to-5’ exonuclease activity.
