For a detailed account of how protein synthesis actually takes
place, see Harun Yahya, The Miracle of Protein, Araştırma Yayıncılık.
This chapter will describe only the general lines of the process as we

show how use is made of the information in DNA.
Protein synthesis is carried out in two stages, known as transcrip-
tion and translation, which permit the information in DNA to be trans-
mitted to RNA, and from there to the proteins.
Transcription, the first step, begins in the cell nucleus. The genetic
information in the double strip of DNA is to be transported by means
of the single-strip RNA molecule.
Translation, the final step in protein synthesis, takes place in the
cell cytoplasm outside the nucleus, where of the genetic information in
RNA is transmitted to new proteins.
Let's now look at the general outlines of these stages:

M Molecules Being Different
In cells, nucleic acids are found in two separate forms: DNA (short
for deoxyribonucleic acid) and RNA (ribonucleic acid), which perform
different tasks. The general differences between the two are as follows:
