The Central Dogma Quiz

What is the process called when DNA makes an identical copy of itself before cell division?

• Protein Translation

• DNA Replication

• RNA Transcription

• DNA Transcription

Which enzyme 'unzips' the DNA strands for copying during DNA replication?

• Helicase

• Ligase

• Polymerase

• Primase

What happens during RNA Transcription?

• RNA nucleotides match with DNA

• DNA unzipping

• Protein building

• DNA zipping back together

What is the role of tRNA in Protein Translation?

• Decodes the mRNA message

• Forms the structure of ribosomes

• Carries the instructions from DNA

• Links amino acids based on mRNA instructions

Which type of RNA carries the instructions from DNA during Protein Translation?

• rRNA

• tRNA

• mRNA

• sRNA

What is the function of rRNA in Protein Translation?

• Carries the instructions from DNA

• Links amino acids based on mRNA instructions

• Decodes the mRNA message

• Forms the structure of ribosomes

What is the specific section of DNA copied into a single-stranded RNA molecule during RNA Transcription?

• Intron

• Exon

• Promoter

• mRNA

Which base pairing rule is followed during RNA Transcription?

• A-T in DNA becomes A-U in RNA

• C-G in DNA becomes C-U in RNA

• A-T in DNA becomes G-C in RNA

• C-G in DNA becomes A-T in RNA

What is the function of mRNA in Protein Translation?

• Links amino acids based on mRNA instructions

• Decodes the mRNA message

• Forms the structure of ribosomes

• Carries the instructions from DNA

What is the role of DNA zipping back together during RNA Transcription?

• Decodes the mRNA message

• Forms the structure of ribosomes

• Carries the instructions from DNA

• Ensures each new cell gets a complete set of instructions
