Where does transcription occur in eukaryotic cells?
Cytoplasm
Ribosome
Nucleus
Mitochondria
What is the role of mRNA in protein synthesis?
Stores genetic code
Carries the genetic code from the nucleus to the ribosomes
Forms the structure of ribosomes
Transports amino acids to the ribosome
Which enzyme is responsible for reading DNA and building mRNA?
DNA polymerase
RNA polymerase
Ribosome
Helicase
What is a key difference between RNA and DNA?
RNA is double-stranded
RNA uses thymine instead of uracil
RNA uses uracil instead of thymine
RNA has deoxyribose sugar
What is the role of mRNA in protein synthesis?
It carries specific amino acids to the ribosome.
It contains the codons that specify amino acids.
It catalyzes peptide bond formation.
It acts as a stop codon.
Which of the following is a start codon in the genetic code?
UAA
UAG
AUG
UGA
What happens during the elongation step of protein synthesis?
mRNA binds to the ribosome.
The ribosome reaches a stop codon.
tRNA with the matching anticodon brings the correct amino acid.
A release factor binds and the polypeptide is released.
What type of mutation involves a single base change in the DNA sequence?
Frameshift mutation
Silent mutation
Point mutation
Nonsense mutation
Which effect of mutation results in a premature stop codon?
Silent
Missense
Nonsense
Frameshift
What can mutations potentially alter in an organism?
The organism's habitat
The organism's diet
The organism's protein structure and function
The organism's lifespan
Which of the following is a cause of genetic disorders?
Regular exercise
Balanced diet
Spontaneous errors in DNA replication
Adequate sleep
What is the role of mRNA in protein synthesis?
To store genetic information
To transport amino acids
To carry the genetic code from DNA to ribosomes
To replicate DNA
How do mutations relate to genetic disorders?
They always prevent genetic disorders
Some mutations in specific genes can lead to genetic disorders
Mutations have no effect on genetic disorders
Mutations cure genetic disorders
