PROFESSOR: All right, start again, what's the hybridization of the carbon atom?

好了，再说一遍，碳原子的杂化轨道是什么？

So again, if we think about that shape of that carbon atom, it's going to be trigonal planar, 120° it's going to have bond angles of 120 degrees, because we have this set up of having three hybrid orbitals.

如果我们考虑碳原子的形状，它是平面三角形，键角是，因为我们有这三个杂化轨道。

An amino acid consists of a carbon atom with four groups of atoms attached to it.

ECONOMIST: Folding stuff

The technique is so sensitive that it can detect a single radioactive carbon atom hiding among a quadrillion (one million billion) ordinary ones.

ECONOMIST: Monitor

Methylation, the addition to a base of a group of three hydrogens and a carbon atom, is one way in which genes are regulated.

ECONOMIST: Nanopores may lead the way to a new generation of sequencing
