Which type of RNA carries the genetic code from DNA to the ribosome?
tRNA
mRNA
rRNA
snRNA
What is the main function of ribosomal RNA (rRNA) in the cell?
To carry amino acids to the ribosome
To form the core of the ribosome and help with protein synthesis
To copy DNA into RNA
To transport genetic information to the nucleus
During transcription, which enzyme is responsible for building the RNA strand?
DNA polymerase
RNA polymerase
Ligase
Helicase
What is the correct order of the steps in the process of translation?
Elongation, Initiation, Termination
Initiation, Elongation, Termination
Termination, Elongation, Initiation
Initiation, Termination, Elongation
Which type of RNA brings amino acids to the ribosome during translation?
mRNA
tRNA
rRNA
snRNA
Given the DNA sequence: 5'-ATG CCA TGA-3', what would be the corresponding mRNA sequence after transcription?
5'-UAC GGU ACU-3'
5'-AUG CCA UGA-3'
5'-TAC GGT ACT-3'
5'-ATG CCA TGA-3'
Explain how tRNA matches the correct amino acid to the mRNA codon during translation.
By using its anticodon to pair with the mRNA codon
By copying the DNA sequence
By forming the ribosome
By breaking down proteins
Why is the process of transcription important for protein synthesis?
It creates ribosomes
It copies the genetic code from DNA to mRNA, which is needed to make proteins
It breaks down proteins into amino acids
It transports amino acids to the ribosome
A mutation changes a DNA base from A to T in a gene. Predict how this might affect the protein produced.
The protein will always be longer
The protein may have a different amino acid, which could change its function
The protein will not be affected at all
The protein will become RNA
A scientist observes that a cell is making a faulty protein. Using your knowledge of the central dogma, suggest one possible reason for this error.
The cell has too much water
There was a mistake during transcription or translation, leading to an incorrect mRNA or amino acid sequence
The cell is not dividing
The ribosome is not made of DNA
