Understanding RNA

Everybody knows a little bit about DNA. Everybody has seen a diagram of it and they understand how important it is. Thing isn't everyone knows about its own cousin RNA. RNA is just as important as DNA since without RNA, DNA wouldn't be in a position to do anything. RNA stands for Ribonucleic acid unlike DNA that stands for Deoxyribonucleic acid. The difference in title simply says that DNA lacks an oxygen one oxygen atom over RNA. However, naturally there are more differences than that.

First if you have seen a diagram of DNA then you will know it resembles a twisting ladder. RNA looks like DNA except its own cut down the center. Therefore it looks like a spiraling thread foundations sticking out towards the center. The coil like DNA is made out of sugar and phosphate. Another distinction is the four letters of DNA is A G C and T the four letters that are in RNA are A G C and U. The U is a version of Thymine (T) called Uracil.

RNA is created by a process known as transcribing. The process of transcribing occurs in 4 measures. The very first thing is when the DNA "unzips" as there bonds break. The next step will be when the free nucleotides (the spiral's) that will develop into the RNA setup with complementary DNA bases. The third step happens as soon as the spirals take shape from the sugar and phosphate and becomes the backbone. Then the fourth step is when the untwisted bonds that occur between the RNA and the unzipped DNA ladder burst. At which point the newly formed RNA leaves through the nuclear pores. At this time it does its own job out in the cytoplasm.

There's more than one kind of RNA. The first type is mRNA (messenger RNA). MRNA is the type of RNA you probably consider when you consider RNA. The task of mRNA is to visit the ribosomes of a cell with a genetic message imprinted to it to tell the ribosomes to create various proteins. Then there is the none-coding RNA named ncRNA. This type of RNA isn't encoded by DNA but rather other RNA. The third type of RNA is called Transfer-Message RNA (tmRNA) tmRNA is used by certain bacteria and viruses.
