It's easy to know what nucleotide to put in each position as you're going along and polymerizing a new molecule.
这使得复制过程中决定下一个核苷酸位点,应该用哪一个核苷酸更为容易
-
Release of tens of thousands, hundreds of thousands of new virus particles from one individual cell such that the cell gets killed in the process of replicating the virus.
从一个独立的细胞中,释放出数以万计甚至,数以十万记的新病毒,这会使细胞就会在,病毒复制的过程中被杀死
-
So, its genetic material wouldn't be released and even if it was released, the genetic material is also cross-linked, and so it can't be transcribed and translated or replicated.
不能释放遗传物质,而且即使能释放遗传物质,该物质也是交联的,因此转录和翻译,即复制过程不能进行
-
If you repeatedly go through this cycle of denaturing, synthesizing, denaturing, synthesizing you'll get many, many copies of DNA.
如果你不断重复这个变性-复制,变性-复制的循环过程,你就会得到很多很多的DNA复制产物
-
Transcription just means making a single stranded RNA copy of a sequence of base pairs in a DNA.
转录的过程就是从一段DNA碱基序列中,复制出一段单链RNA
-
That's synthesis and that has to happen in order for cells to replicate and cell replication is happening in your body all the time.
这个DNA合成过程是,细胞复制中不可或缺的部分,细胞复制时刻不停的在你身体里进行着
-
The result of this process if this replication went down the whole length of the DNA would be to form two identical, double stranded DNA molecules.
如果复制过程在整条链上持续进行的话,将生成两条完全一样的,双链DNA分子
-
It's totally synthetic, there's no micro-organism involved in making the DNA for you, You can do it very rapidly in a laboratory, and fairly inexpensively now.
完全是复制的过程,没有任何微生物参与制造DNA,你可以在实验室里迅速地进行,费用现在也相当便宜了
-
What's shown here is what's called a replication fork in DNA that's undergoing synthesis.
这里展示的是在DNA合成过程中,形成的DNA复制叉
-
A primer is a short RNA sequence or DNA sequence that gets sort of the process of replication jump started, and that's just because of the biological properties of DNA polymerase that that primer's needed.
引物是一段短的RNA或者DNA序列,引物是整个复制的起点,因为DNA聚合酶的,生物特性,引物在复制过程是必不可少的
-
Synthesis always occurs in one direction and that makes sense to you now because you know there's a directionality and the chemistry is different going one way than the other and this DNA polymerase only works on the chemistry going in one direction.
NA复制过程是单向的,现在你们该明白原因了,因为DNA单链有方向性,DNA在两个方向上化学性质不同,DNA聚合酶,只在一个方向上起作用
-
Certain segments of DNA are being converted into RNA, and whereas in replication, you have to copy the whole genome, the whole - all of the chromosomes, all of the DNA contained in the chromosomes of the cell in order to completely replicate it; transcription only works on particular sequences of DNA.
特定的DNA序列被转录为RNA,在复制的过程中,整条染色体都被复制,包括其中的全部DNA序列,都被分毫不差地复制下来,以保证复制的完整性,而转录过程只发生在特定的DNA序列上
