DNA particles that mimic viruses hold promise as vaccines
网页2024年1月30日 · Using a virus-like delivery particle made from DNA, researchers from MIT and the Ragon Institute of MGH, MIT, and Harvard have created a vaccine that can induce a strong antibody response against SARS-CoV-2. The vaccine, which has been tested in mice, consists of a DNA scaffold that carries many copies of a viral antigen.
Memory-making involves extensive DNA breaking - MIT News
网页2021年7月14日 · To provide access to genes needed for the encoding and storage of memories, brain cells snap open their DNA, breaking both strands. A new study finds this happens more extensively than previously realized and it occurs not only in neurons but other supporting cell types.

10 unexpected ways Neanderthal DNA affects our health
网页2024年5月17日 · For example, a 2020 study published in the journal Nature found that Neanderthal DNA on chromosome 3, which is carried by 16% of Europeans and 50% of South Asians, is associated with an increased ...
Scientists preserve DNA in an amber-like polymer - MIT News
网页2024年6月13日 · Capturing DNA. DNA, a very stable molecule, is well-suited for storing massive amounts of information, including digital data. Digital storage systems encode text, photos, and other kind of information as a series of 0s and 1s. This same information can be encoded in DNA using the four nucleotides that make up the genetic code: A, T, G, and C.

网页2021年6月10日 · Currently, DNA files are conventionally retrieved using PCR (polymerase chain reaction). Each DNA data file includes a sequence that binds to a particular PCR primer. To pull out a specific file, that primer is added to the sample to find and amplify the desired sequence.
Untangling DNA knots | MIT News | Massachusetts Institute of …
网页2018年5月3日 · A knot near the end of a stretched DNA molecule is driven toward the end and unties, leaving an unknotted molecule. (Image: Alex Klotz) The MIT team found that they could manipulate knots in these pinned DNA molecules by varying the strength of the electric field. When the field is weak, knots tend to …
