Replication, Transcription and Translation

Where is the DNA located inside the cell?

• Ribosome

• Endoplasmic reticulum

• Golgi apparatus

• Nucleus

Where in the cell is DNA transcribed into mRNA?

• Cytoplasm

• Ribsome

• Nucleus

• Mitochondria

What are the subunits of DNA and RNA?

• simple sugars

• amino acids

• nucleotides

• carbohydrates

What does the DNA polymerace do during DNA replication?

• It replicates tRNA, mRNA, and rRNA

• It adds A-U-G-C as compliments to the original strand of DNA

• It adds complimentary free nucleotides to the original strand of DNA

• It unzips the DNA

Check all the ones that apply to RNA

• single strand

• uracil

• large molecule

• leaves the nucleus

• unable to leave the nucleus

What is the purpose of protein synthesis?

• to make a protein (polypeptide)

• to make mRNA

• to make an amino acid

• to copy DNA

During protein synthesis, what does mRNA do?

• it strings together two complementary DNA strands

• it constructs proteins out of random amino acids

• it delivers DNA's instructions for making proteins to the ribosome

• it constructs proteins out of random amino acids

Translation takes place in the 

• ribosome

• chloroplast

• nucleus

• mitochondria

Brings the amino acids to the ribosome

• mRNA

• tRNA

• rRNA

• DNA

What would happen if we did not have start codons?

• Polypeptide chains would continue to grow

• Amino acids would bind to tRNA

• Protein synthesis wouldn't occur

• mRNA would form a double strand
