Question

Which 3 statements describes proteins?

Proteins are created from the code in DNA.

Proteins are synthesized in the nucleus of a cell.

DNA and RNA are proteins.

Amino acids are the building blocks of proteins.

Proteins affect the structures and functions of living things.

The shape and the function of a protein are not related.

Answer 1

1,4,5

Step-by-step explanation:

1,because proteins are synthesized by ribosomes which get the coded mRNA from the nucleus of the cell and these mRNA are also gets it's code from the cods on DNA molecule. so proteins are created from the coded in DNA.

4,proteins are build in cytoplasm by ribosomese because ribosomes accept the mRNA and then tRNA comes attached amino acid and translate the code in mRNA to protein molecule. so Amino acids are building blocks of protein.

5,proteins are almost the building block of every life. proteins affect the structure of life because all life cells are made from proteins. proteins also affect the functions of life because all the chemical reactions are controlled by enzymes which are proteins.
