Now don't think of longevity noodle as a single strand like spaghetti.

但可别以为长寿面就是像意大利面那样是一条条的。

How curly a single strand of human hair gets depends on the hair follicle it's growing out of.

一根人类头发的卷曲程度取决于它长出来的毛囊。

HIV is a single-stranded, positive-sense, enveloped RNA retrovirus, meaning that it injects its single strand of RNA into the T-helper cell.

HIV是单链、正义、有囊膜的RNA逆转录病毒，也就是说，病毒会将单链DNA注入辅助T细胞中。

Good and evil are like a white and a black thread that make up a single strand.

善与恶就像一条白线和一条黑线，合而为一。

To offer a sense of perspective, a single strand of human hair is approximately 80,000 nm wide.

为了提供透视感，一根人类头发的宽度约为 80,000 纳米。

They produce a lot of silk, too — each one spins a cocoon from a single strand that can be up to 1, 000 meters long.

并且它们可以生产出大量的蚕丝——每个蚕茧都是由一根长达1000米以上的蚕丝裹成的。

Each single strand of DNA is composed of a sequence of four types of nucleotides - which are the individual letters or building blocks of DNA.

每一条DNA单链都是四种核苷酸组成的序列；核苷酸是DNA的基本组成单位。

Rapunzel gets around this problem by throwing down a big braid or ponytail of hair, instead of a single strand.

长发公主通过扎一条大辫子或马尾辫来解决这个问题，而不是单链。

So this means, if we take 400 of our nanoparticles and we stack them on top of each other, we get the thickness of a single hair strand.

这意味着四百个纳米粒子一个一个叠在一起，就是一根头发的厚度。

So if you make a staple strand with the right pattern of bases it will bind to the single strand piece of DNA automatically.

所以如果你用正确的碱基模式制造一条短链，它会自动结合到单链 DNA 上。

They mean that a single strand of hair is about half as strong as a piece of steel the same size, notes Ray Goldstein.

Ray Goldstein 指出， 它们意味着一根头发的强度大约是一块相同尺寸的钢材的一半。

Kolinsky hairs are chosen because every single strand has a surface of directional, interlocking scales, increasing the surface area and giving the hairs their strength.

之所以选择 Kolinsky 毛发， 是因为每根单线都有一个定向的、互锁的鳞片表面，增加了表面积并赋予了毛发强度。

This technique solves the equations for liquid motion along every single hair strand, computes the cohesion effects between the hairs, and it can also simulate the effect of water dripping off the hair.

这项技术需要求解沿着每根发丝的液体运动方程、计算发丝之间的集聚效应并且模拟水从头发上滴落的情形。

A spider's web is incredibly strong though, with a tensile strength 5 times greater than steel, and yet is incredibly lightweight- a single strand that encircled the globe would weigh only 1 pound 2 ounces.

蜘蛛网非常坚固，抗拉强度是钢的 5 倍，而且非常轻——单根蜘蛛网环绕地球仅重 1 磅 2 盎司。
