how do you do transcription and translation? simple step by step instructions would be the best. thanks
This is to make a resulting amino-acid code. In simple terms: transcription comes first. So RNA polymerase "opens up the DNA and copies it into a resulting RNA sequence. This is called mRNA, which is single stranded.
Next up is translation, where the mRNA is transferred to the cytoplasm (from the nucleus) where it goes to a ribosome.
What you need to know is that there are 4 letters of DNA, A,T, G,C where A is the opposite of T. G is the opposite of C. By opposite I mean that if one side of the DNA double helix has a letter A, then the letter opposite from it would have a letter T
RNA works just the same way except instead of A going to T is goes to U. But if there is a T for DNA than the resulting RNA letter would be A. You can look up the full form of the letters if you want
Another thing you need to know is what a codon is. Remember those letters I was talking about? Well a codon is read in pairs of 3. Like 3 letters at a time. So the mRNA has its many letters and they go to a ribosome where they are written in groups of three. Those groups of three specify a specific amino acid. For example, AUG = methionine
As said in the previous example, if the codon is AUG, than a transfer RNA will bring an anticodon (which is the exact opposite base pairs of the codon but is attached to the amino acid that the codon codes for).
Those amino acids make proteins.
