How proteins are made​
Ira Lisetskai [31]

Proteins are an important class of molecules that carry out most of the work inside cells. The building blocks of proteins are smaller organic molecules called amino acids. Most organisms, including humans, use only 20 different amino acids to assemble the vast multitude of proteins needed to build and run a cell.

To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.  

After the polypeptide chain is synthesized, it will sometimes undergo additional processing. For example, some proteins will have certain amino acids removed. Or extra molecules such as sugars or phosphates may be attached to some of the amino acids in a protein.

patriot [66]

Answer:

The adopted child is the one with type O blood.  

Explanation:

<u>Available data:</u>

  • A man with type AB blood is married to a woman with type O blood.
  • They have two biological children and one adopted child.

The man´s genotype for blood type is AB (Codominant type of blood) and the woman´s genotype for blood type is OO, as this type of blood is expressed by two recessive alleles.

Cross:

Parental)  AB   x   OO

Gametes) A   B   O   O

Punnet square)      A      B

                        O    AO   BO

                        O    AO   BO

F1) Half of the biological progeny will be AO and the other half BO.  

   There are no possibilities that any of the biological child could be OO. This means that the adopted child´s blood type is O and the biological children´s blood type are A and B.
