What's hanging off of the side of this long molecule that's formed by polymerizing nucleotides are - is this base unit.
在这条由多聚核苷酸,构成的长链分子,一侧悬挂着碱基单位
And these tree trunks were the chords and at the base of each of these chords at least conceptually, theoretically, is this thing called the root.
这些树干就是和弦,而每个和弦的底部,从理论上说,就是被称为根的东西。
Jacob Milgrom sees a moral message at the base of this complex, symbolic picture. And that is that humans and humans alone are responsible for the rein of wickedness and death or the rein of righteousness and life.
米尔格罗姆在这这个复杂的基础上看出了一个道德上的信息,一副象征性的图画,那就是人类,应该单独承担起驾驭邪恶与死亡,正义和生存之间的责任。
This is our little sanity check, the base case.
这是合法性检查,是基本条件。
People in serious accidents with their paralysis as the result of the accident, very often, usually-- again, this is all the average-- go back to their base level of happiness: if they are happy before, they will be happy one year after; if they are unhappy, they will remain unhappy.
遇到严重意外的人,意外导致瘫痪,经常地,一般性的…,再次强调,这是平均而言-,都会恢复到基础幸福水平:,他们以前是快乐的,一年后,他们也会快乐;,如果不快乐,将维持不快乐。
Yeah. You're jumping slightly ahead of me, but basically, I'm done when this is equal to 1 right? Because I get down to the base case, so I'm done when b u is over 2 to the k is equal to 1, and you're absolutely right, that's when k is log base 2 of b.
因为这就是最基本的情况了,因此当b/2的k次方等于1的时候就停止了1,你说的太对了,就是k等于b的以2为底的对数的时候,你们都坐的挺靠后的啊,我不知道是不是我讲的不太明白?
e This is just base e, natural logarithm.
减去EXP自然对数中的。
But mathematically, we've mentioned this before, log N or really to be precise, log base 2 of N, is the way you express this mathematically.
但从数学上说,之前我们已经提到过了,准确地说是log,N,以2为底N的对数,这就是它在数学上的表示。
You know that messenger RNA is read in three base units called codons, and so this particular piece of messenger RNA is drawn in this cartoon in three base pair units.
RNA是按每三个碱基组成一个密码子,进行翻译的,在这幅动画中所画的mRNA,就是按三个碱基一组的方式来描绘的
This label is DNA that might be made radioactive or made fluorescent, and it has a base pair sequence that is from some other region of the gene that you're interested in.
这种标签就是具有放射性,或者荧光性的DNA,它有一个取自于,你感兴趣的那段基因上,其他位置的碱基对序列
This particular base is , this is ribose.
这个特别的碱基是A,这个是核糖
Well one way you could do it is by saying 'if I have this one base pair difference then this sequence is going to be cut by a specific restriction enzyme that recognizes the sequence CTGAGGA'.
一种方法是通过考虑,"如果我有这个不同的碱基对,那该序列必然会,被特定的限制酶识别并切割,这个特定的限制酶能识别,CTGAGGA "
The native structure is this double stranded structure here and if I heat it up slightly and I add some base, so under slightly basic conditions, these molecules will fall apart because you've created conditions where the hydrogen bonding is no longer favorable so they peel apart.
原始结构,在这里就是指DNA双链,如果我稍微加热,并且加入一些碱,在弱碱性的条件下,这些配对碱基会分开,这是因为在一定条件下,碱基对之间的氢键,不再稳定并且会断裂分开
