Protein synthesis

Genes

Dna contains what?

Polypeptides

These genes code for what?

Proteins

     are used to build cells and do much of the work inside cells.

Amino acids

proteins are made of__linked together by peptide bonds

Nucleus

DNA is found inside the

proteins

     are made in the cytoplasm of cells by organelles called ribosomes.

Ribosomes

     may be free in the cytosol or attached to the surface of rough endoplasmic reticulum.

DNA’s code

must be copied and taken to the cytosol.

protein synthesis

this code must be read so amino acids can be assembled to make polypeptides (proteins). This process is called

RNA

the blueprint

DNA

the master plan

RNA

has a sugar ribose

DNA

has a sugar deoxyribose

Uracil

RNA contains the base

Thymine

DNA contains the base

RNA molecule

single stranded

DNA molecule

double stranded

Ribosomal RNA

     along with protein, makes up the ribosomes.

messenger rna

     copies DNA’s code and carries the genetic information to the ribosomes.

transfer rna

     transfers amino acids to the ribosomes where proteins are synthesized.
