16 Questions
During transcription, what is the role of RNA polymerase?
Unzipping the DNA and reading one of the DNA nucleotide strands
Which process is responsible for the transfer of genetic instructions from DNA to mRNA?
Transcription
What is the start codon in the process of translation?
AUG
Which of these represents the language of DNA?
Sequence of nucleotides
Where does the folding process of amino acids occur after an amino acid chain is made?
Rough ER
What occurs when the ribosome reaches a stop codon during translation?
The amino acid chain is released
What is the role of tRNA in translation?
Bringing amino acids to the ribosome based on the mRNA codon sequence
What is the function of rRNA in translation?
Bonding to the ribosome and moving along until it finds the start codon
What is the universal feature of the genetic code?
All known living things have the same genetic code
Which step does RNA polymerase perform during transcription?
Reading one of the DNA nucleotide strands and attaching complimentary RNA nucleotides to that strand
Where does transcription take place in a cell?
Nucleus
What is the main function of messenger RNA (mRNA)?
Carry instructions to the ribosome for protein synthesis
Which nitrogen base is present in RNA instead of thymine?
Uracil
What is the function of transfer RNA (tRNA) in protein synthesis?
Bring amino acids to ribosomes for protein formation
What is the structure of ribosomal RNA (rRNA) mainly associated with?
Structure of ribosomes
What differentiates RNA from DNA in terms of their sugar components?
RNA consists of ribose, unlike deoxyribose in DNA
Test your knowledge about the processes of transcription and translation in protein synthesis. Learn about how cells use DNA to create RNA, and how RNA is then translated into proteins in the cytoplasm. Understand the differences between RNA and DNA in this quiz.
