Faith Schutt Protein Synthesis Practice

Assign each of the characteristics below to either DNA or RNA.

Protein synthesis occurs in which order?

The process of copying a gene's DNA sequence into a sequence of RNA is called:

Which process is shown in the image below?

Use the image below to answer the following questions:

Hint: not ALL of the labels are used!

Put the steps of transcription and translation in the order that they occur in.

1. Amino acids are added together with peptide bonds to make a protein. Translation is complete.
2. RNA nucleotides match their bases to the bases on one of the DNA strands and a strand of mRNA is made.
3. Transcription begins when DNA is "unzipped" beginning at a start codon.
4. Codons on the mRNA pair up with anti-codons on the tRNA, which brings in the correct amino acids.
5. The Stop codon is reached and mRNA leaves the nucleus with the copied strand of DNA.
6. mRNA connects to the ribosome and translation begins.

Transcribe the following DNA:

ATT CCC GGG

Translate mRNA: UUU AAA GGG to Amino acid sequence

Translate the following DNA sequence into Amino acids:

ATA GCG GTG

Translate the following DNA sequence into Amino acids:

AAA CGC ATA CCA

From what DNA Strand was this mRNA: CUC AAG UGC UUC made ?

Write the sequence of mRNA bases that would be transcribed from the sequence of bases below:

TAC ACG CAA TTA

Use the space bar to separate your sequence into codons.

Use the genetic code chart provided above to translate your MRNA from Question 12 into an amino acid sequence to make a protein. Use the first 3 letters of each amino acid in your answer and separate each of your amino acids from the others with a space. Example: MET HIS PRO LEU STOP
