DNA to Proteins Unit Test Review

Define protein synthesis.

• The process in which a strand of DNA is copied into an RNA strand

• The production of a protein molecule through DNA transcription and translation

• Cells that are specialized to perform a specific function

• The process by which the sequence of nucleotides in a messenger RNA is converted by a ribosome and transfer RNAs into a polypeptide with a specific sequence of amino acids

Match the following

• Single-stranded

• RNA

• Ribose

• RNA

• Double-stranded

• DNA

• Deoxyribose

• DNA

Reorder the following steps of transcription:

• After leaving the nucleus, the mRNA travels to the ribosome.

• Adenine-->Uracil,

  Guanine-->Cytosine,

  Thymine-->Adenine,

  Cystosine-->Guanine.

• DNA unzips and creates a template for mRNA to form.

• A single strand of mRNA leaves the nucleus through a nuclear pore.

What is a catalyst?

• They slow down chemical reactions within cells of living organisms.

• They stop chemical reactions within cells of living organisms.

• They accelerate chemical reactions within cells of living organisms.

• They heat up chemical reactions within cells of living organisms.

In the "Make Me A Sandwich" Lab, what part of the cell did the sandwich shop owner represent?

• rough ER

• nucleus

• ribosome

• smooth ER

What is the function of the rough ER?

• genetic code

• packages the protein

• builds the protein

• carries amino acids used to build proteins
