Unit 7

In what process is mRNA synthesized?

• Transcription

• Translation

• DNA Replication

• Mitosis

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

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

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

GTACAT

• CATGTA

• GAUCUA

• CAUGUA

• CUTGTU

What brings the amino acids to the ribosome to assemble a protein?

• mRNA
• tRNA
• rRNA
• DNA

How many nucleotides code for 1 amino acid?

• 1

• 2

• 3

• 4

When these bond together, they form a protein

• Amino Acids

• Peptide Bonds

• Ribose

• Nucleotides

The process to go from mRNA to a protein is called ____

• transcription
• rRNA
• replication
• translation

Which process does this diagram illustrate?

• transcription

• DNA replication

• translation

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
