What does adenine go with

The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine. Base pair describes the relationship between the building blocks on the strands of DNA.

And each of the nucleotides on one side of the strand pairs with a specific nucleotide on the other side of the strand, and this makes up the double helix. So for example, if there's a G on one side of the strand, there will always be a C on the other. If there's a T on one side of the strand, there will always be an A on the other. Day-to-Day Life.

At this point, at least in eukaryotes, the newly synthesized mRNA undergoes a process in which noncoding nucleotide sequences, called introns , are clipped out of the mRNA strand. This process "tidies up" the molecule and removes nucleotides that are not involved in protein production Figure 6.

Then, a sequence of adenine nucleotides called a poly-A tail is added to the 3' end of the mRNA molecule Figure 7. This sequence signals to the cell that the mRNA molecule is ready to leave the nucleus and enter the cytoplasm. What's next for the RNA molecule? More on transcription. How are polymerases different in prokaryotes and eukaryotes?

How is bacterial transcription unique? How is transcription regulated? Once an mRNA molecule is complete, that molecule can go on to play a key role in the process known as translation. During translation , the information that is contained within the mRNA is used to direct the creation of a protein molecule.

In order for this to occur, however, the mRNA itself must be read by a special, protein-synthesizing structure within the cell known as a ribosome.
