Genes, in turn, are made of DNA, helical strands of compounds called nucleotides that contain chemicals called bases.

反过来，因是由DNA，即核苷酸的螺旋链组成，核苷酸含有一种叫做碱的化学物质。

Nucleotides are the building blocks of DNA and RNA.

核苷酸是 DNA RNA 的组成部分。

Usually, for gene expression, nucleotides are read in groups of three.

通常对于因表达来说，核苷酸以一组被读取。

Each composition of this nitrogenous base, pentose sugar, and phosphate group is called Nucleotide.

这种含氮碱、戊糖磷酸的每一种组成称核苷酸。

That's because the instructions carried by genes are read in sets of three nucleotides.

因因携带的指令是被一组的核苷酸读取的。

This is because of a particular single nucleotide polymorphism on my BCMO1 gene.

这是因我的 BCMO1 因具有单核苷酸因多态性。

But the synergy happens when you add certain kinds of nucleotides.

It is a polymer, and it is made up of lots of nucleotides that contain bases.

它是一种聚合物，由许多含有碱的核苷酸组成。

Like DNA, RNA is made up of a long chain of nucleotides.

DNA 一样，RNA 是由一长串核苷酸组成的。

That “form” is called ATP, if you're familiar with that.

如果你熟悉这种形式的话，它的名字叫做 ATP（嘌呤核苷磷酸）。

Each nucleotide contains a phosphate group, a sugar group, and a nitrogen base.

每核苷酸包含一磷酸、一糖一氮。

But most SNPs have no known effect at all.

但大多数单核苷酸多态性根本没有已知的影响。

Then it starts to make more, using a bunch of different chemical reactions.

然后身体利很多不同的化学反应开始制造更多的嘌呤核苷磷酸。

RNA polymerase also then binds the RNA nucleotides together making a new RNA strand.

The nucleotides on one strand pair up using hydrogen bonds with nucleotides on the opposing strand to create the double-stranded DNA.

一条链上的核苷酸通过氢键与相对链上的核苷酸配对，形成双链DNA。

This is known as a single nucleotide polymorphism, or SNP, familiarly known to biochemists as a Snip.

这种情况被称单一核苷酸多样型（SNP），也就是生化学家所说的Snip。

Within the DNA of the cells in these polyps, there are specific stretches of nucleotides that are called CpG islands.

息肉细胞的DNA中有一些特定的核苷酸序列被称CpG岛。
