PROTEINS CANNOT FORM WITHOUT THE
HELP OF OTHER PROTEINS
Now, based on what we have seen so far, let’s understand
why in order for a single protein to form, the help of many other
proteins is needed. First let’s summarize what features the
amino acid chains in the proteins need to have:
1. Of the more than 200 varieties of amino acid in living
structures, only 20 (some use 22) can be used for protein syn-
thesis. The ones necessary for the protein need to be selected
out of 200 amino acids available.
2. The selected amino acids must all be left-handed, not
right-handed. Only left-handed amino acids can be used for the
protein synthesis in living things.
3. The amino acids must be arranged in a particular se-
quence.
4. Proteins are required to copy the relevant information
about the protein inside the DNA and to carry out all other sub-
sequent processes. Therefore, proteins must already be present
in the same environment, ready to carry out those tasks.
5. A ribosome –an organelle of the cell- is required to carry
out the synthesis using the copied data. However, the ribosome
itself is made up of ribosomal proteins and rRNA (ribosomal
RNA); in other words, in order for the ribosome to exist, other
proteins must have existed previously.
6. Inside the ribosome, there is a hydrophobic area (water-
repellent) called ‘peptidyl transferase’ that allows amino acids to
bind together. This structure, which is an enzyme itself, pushes
the water away, and then with its catalytic features allows pep-
tide bonds to form.
Clearly, it is impossible for the above conditions to gradu-
ally and randomly come into existence and give rise to a pro-
