  2. Pentyl propanoate - Wikipedia

    en.wikipedia.org/wiki/Pentyl_propanoate

    Pentyl propanoate (also known as amyl propionate) is an organic ester formed by the condensation of pentan-1-ol and propanoic acid. [2] It is a colorless liquid with an apple-like odor, that floats on water.

    en.wikipedia.org/wiki/List_of_esters

    Esters of carboxylic acids with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Phosphoesters form the backbone of DNA molecules. Nitrate esters, such as nitroglycerin, are known for their explosive properties, while polyesters are important plastics, with monomers linked by ester moieties.

    The result in the truncated DNA is the same. Some reagents, e.g. DMS, sometimes do not block the reverse transcriptase, but trigger a mistake at the site in the DNA copy instead. These can be detected when using high-throughput sequencing methods, and is sometimes employed for improved results of probing as mutational profiling (MaP). [14] [15]

    For pure DNA, A 260/280 is widely considered ~1.8 but has been argued to translate - due to numeric errors in the original Warburg paper - into a mix of 60% protein and 40% DNA. [6] The ratio for pure RNA A 260/280 is ~2.0. These ratios are commonly used to assess the amount of protein contamination that is left from the nucleic acid isolation ...

    en.wikipedia.org/wiki/Pentyl_pentanoate

    Pentyl pentanoate (C 4 H 9 COOC 5 H 11) is an ester used in dilute solution to replicate the scent or flavour of apple, and sometimes pineapple. [1] It is referred to as pentyl valerate or amyl pentanoate using classical nomenclature. it can be used for a variety of chemical uses, such as in the production of flavoured products, like sweets.

  8. Homing endonuclease - Wikipedia

    en.wikipedia.org/wiki/Homing_endonuclease

    Homing endonuclease recognition sequences are long enough to occur randomly only with a very low probability (approximately once every 7 × 10 9 bp), [2] and are normally found in one or very few instances per genome. Generally, owing to the homing mechanism, the gene encoding the endonuclease (the HEG, "homing endonuclease gene") is located ...

  9. Proliferating cell nuclear antigen - Wikipedia

    en.wikipedia.org/wiki/Proliferating_cell_nuclear...

    The protein encoded by this gene is found in the nucleus and is a cofactor of DNA polymerase delta. The encoded protein acts as a homotrimer and helps increase the processivity of leading strand synthesis during DNA replication. In response to DNA damage, this protein is ubiquitinated and is involved in the RAD6-dependent DNA repair pathway ...
