Protein Synthesis and Reading a Codon Chart

In which step is an mRNA copy of a gene made (so that it can leave the nucleus)?

• Transcription

• Translation

• S Phase

• Meiosis

What enzyme unwinds DNA and makes an mRNA copy of the gene in the process of transcription?

• Helicase

• DNA Polymerase

• RNA Polymerase

• Ribosome

• tRNA

Click all that are correct: Which of these happen in translation?

• RIbosome attaches to the start codon AUG

• Ribosome reads the codons of mRNA and provides a site for tRNA to attach

• tRNA bring specific amino acids to be linked together

• Ribosomes link the amino acids together to form a protein polymer

• Ribosome releases the mRNA when it reaches a stop codon

Which of these is the product of translation? (Which of these are made in translation?)

• mRNA copy of a gene

• Copy of a DNA chromosome

• Protein polymer (polypeptide)

• Ribosome

In translation, each ____ carries a specific amino acid and delivers it so that it can be attached to other amino acids to make a polypeptide / protein.

• Messenger RNA (mRNA)

• gene

• RNA polymerase

• Ribosome (Ribosomal RNA (rRNA))

• Transfer RNA (tRNA)

In Transcription, RNA polymerase uses the DNA code to make an mRNA copy of the gene.

• UAC UUC CGA GCG

How many nucleotides (mRNA letters) make up a codon on mRNA?

• 1

• 3

• 5

• 15

Here is a section of mRNA:

• Phenylalanine

• Tyrosine

• Leucine

• Methionine
