Biology Protein Synthesis

Why must transcription occur in the nucleus?

• because DNA can't leave the nucleus

• because ribosomes are in the nucleus

• because DNA polymerase is found there

• because helicase unzips the DNA

Choose the sequence of the mRNA strand that would match up with to the following DNA strand:

GTACAT

• CATGTA

• GAUCUA

• CAUGUA

• CUTGTU

What determines the shape and function of a protein?

• The sequence of amino acids

• The type of ribosome that assembles the protein

• The cell that manufactures the protein

True or False: mRNA contains anticodons and tRNA contains codons.

• True

• False

How are DNA and RNA different? (CHECK ALL THAT APPLY)

• Only DNA can leave the nucleus

• RNA contains Thymine; DNA contains Uracil

• DNA is double stranded, RNA is a single stranded

• DNA contains Thymine, RNA contains Uracil

Which organelle is the location where protein is made?

• Ribosome

• Nucleus

• Cytoplasm

• Nucleotide

A string of nucleotides that contain the information to make a specific protein

• Ribose

• Amino Acids

• tRNA

• Gene

The main function of tRNA is to...

• carry a message that, when translated, forms proteins

• form a portion of ribosomes

• string together complementary RNA and DNA strands

• bring amino acids from the cytoplasm to the ribosomes

Which phrase best describes translation?

• converts mRNA into a polypeptide

• catalyzes bonds between amino acids

• produces RNA from DNA molecules

• recycles tRNA molecules for reuse

Which of the following is the site of translation?

• vacuole

• lysosome

• nucleus

• ribosome
