What makes the human brain distinctive? A new study published in Cell identifies two genes linked to human brain features and ...

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.

The finished sequence of human chromosome 20 comprises 59,187,298 base pairs (bp) and represents 99.4% of the euchromatic DNA. A single contig of 26 megabases (Mb) spans the entire short arm, and ...

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 ...

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 ...

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 ...
