Explain briefly the process of transcription and translation and the differences between the molecules involved.
Transcription is the process in which DNA will be transcribed into mRNA in the nucleus. DNA consists of a double helix and is made up by four bases: Adenine, Thymine, Cytosine and Guanine. mRNA is single stranded and consists of 4 bases as well which are the same as DNA, only Thymine is replaced by Uracil. Translation is the process in which mRNA will be translated into proteins by ribosomes outside of the nucleus. Proteins consists of 20 different Amino Acids and have different structures dependant on the amino acid configuration (for example alpha helices and beta sheets).
