Example Sentences

These mutations, which prevent the p53 protein from forming a tetramer -- an assembly of four p53 proteins -- had been studied before, using a technique that involves inserting artificial copies of a mutated p53 gene into a cell.

From Science Daily

However, when the MIT team introduced those same mutations using the new prime editing technique, they found that the mutation prevented the tetramer from forming, allowing the cells to survive.

From Science Daily

Each nucleosome consists of approximately 147 base pairs of DNA wrapped around a histone octamer which is composed of two H2A-H2B dimers and one H3-H4 tetramer.

From Science Daily

Further analysis using X-ray crystallography and thermodynamic simulations revealed that tetramer formation is driven by hydrophobic interactions occurring between two 3D-DS dimers.

From Science Daily

The formation of the 3D-DS tetramer can help prevent protein aggregation by decreasing flexibility, potentially avoiding the formation of insoluble aggregates.
