Protein
Synthesis - Protein synthesis consists of two main events, transcription and translation . Transcription is the copying of a complementary messenger RNA strand on a DNA strand. The DNA strand unwinds and one of the two strands forms an mRNA strand. The nucleotides of mRNA are complementary to those of the DNA strand.
However, in mRNA uracil (U) replaces thymine (T) of DNA. As a result the complementary pairing is A-V and G-C. The mRNA makes its way through the pores in the nuclear membrane to the cytoplasm. Here it forms a complex with a group of ribosomes (polyribosome)
