Proteins are polymers--long chains of many similar building blocks linked by covalent bonds. There are 20 building blocks, or monomers, that are used to build proteins. These monomers share a common structure.

The given question is incomplete as question is not specified however the complete question is as follows:

Proteins are polymers--long chains of many similar building blocks linked by covalent bonds. There are 20 building blocks, or monomers, that are used to build proteins. These monomers share a common structure.

Drag the labels to the appropriate blanks on the diagram. (diagram is attached)

The correct answer is - amino acid is in top box, side chain is in the second number, amino group in bottom left and carboxyl group in bottom right box.

Explanation:

Amino acid is the building block of the protein that are linked covalent bonds. These are the monomers of the proteins. There are twenty different amino acids that share common structure the only difference is in their confirmation and arrangement.

Amino acids have A side chain that is attached to the carboxyl group and amino group in their general structure.

Thus, the correct answer is - mino acid is in top box, side chain is in the second number, amino group in bottom left and carboxyl group in bottom right box.

idk im sorry.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
