What is the role of ribosomes in protein synthesis?
Ribosomes play a crucial role in protein synthesis by facilitating the translation of mRNA into polypeptide chains.
Ribosomes are responsible for DNA replication
Ribosomes store genetic information
Ribosomes help in cell division

4
3
6
What is the start codon in the genetic code?
UAC
UAA
AUG
UAG
What is the anticodon of a tRNA molecule?
A type of protein
Sequence of three nucleotides
A specific gene sequence
A chemical compound
What is the final product of protein synthesis?
polypeptide chain or protein
carbohydrate
nucleotide
amino acid
Explain the difference between transcription and translation in protein synthesis.
Transcription copies DNA into mRNA, while translation decodes mRNA to build a protein.
Transcription builds proteins directly from DNA, while translation copies DNA into mRNA.
Transcription decodes DNA into mRNA, while translation copies mRNA to build a protein.
Transcription and translation are the same process in protein synthesis.
What is the function of mRNA in protein synthesis?
mRNA brings amino acids to the ribosome
mRNA decodes the tRNA sequence
mRNA carries the genetic information from DNA to the ribosome
mRNA synthesizes proteins directly
What is the role of DNA polymerase in DNA replication?
DNA polymerase unwinds the DNA double helix
DNA polymerase adds nucleotides to the growing DNA strand
DNA polymerase transcribes DNA into mRNA
DNA polymerase translates mRNA into proteins
How does the genetic code determine the sequence of amino acids in a protein?
By directly coding for amino acids
By specifying the order of tRNA molecules
By using codons to represent specific amino acids
By regulating the function of ribosomes
Explain the role of mRNA in protein synthesis.
mRNA brings amino acids to the ribosome
mRNA decodes the tRNA sequence
mRNA carries the genetic information from DNA to the ribosome
mRNA synthesizes proteins directly
What is the function of rRNA in protein synthesis?
rRNA brings amino acids to the ribosome
rRNA decodes the mRNA sequence
rRNA forms the structure of ribosomes and helps in protein synthesis
rRNA regulates gene expression
