Researchers have identified two genes from the human genome’s “dark matter” that influence brain size and synaptic signaling.

ASSESSMENT. Student Handout Questions Procedure Step 1: Sample description of the main steps of the Sanger method of DNA sequencing. Student answers will vary, but they should include: Scientists ...

DNA sequencing was revolutionized after scientists discovered a new bacterium in the hot springs of Yellowstone National Park ...

For example, the activity of genes can be altered by what are called epigenetic modifications—a chemical alteration of some bases that don't change the DNA sequence.

Because sequencing is performed on a sample that contains both maternal and placental DNA, it is not surprising that many false positive results are of maternal origin. 32 In one study, two thirds ...

This Review presents a quantitative framework for translating DNA sequences into transcriptional behaviours. Such a model, based on the binding affinity landscape of molecules to genomic sequences ...

A tooth from a mammoth that roamed the Siberian steppe more than a million years ago has yielded the world’s oldest DNA sequence. It’s the first time that DNA has been recovered from animal ...

The recognition of specific DNA sequences by proteins is thought to depend on two types of mechanism: one that involves the formation of hydrogen bonds with specific bases, primarily in the major ...
