DNA & Protein Synthesis

What is translation in the context of protein synthesis?

• The process of synthesizing DNA from RNA.

• The process of decoding mRNA to synthesize proteins.

• The process of folding proteins into their functional shapes.

• The process of replicating DNA before cell division.

What is the function of ribosomes in protein synthesis?

• Ribosomes are the sites where proteins are assembled.

• Ribosomes transport amino acids to the nucleus.

• Ribosomes break down proteins into amino acids.

• Ribosomes synthesize DNA from RNA.

What base in DNA pairs with Adenine?

• Cytosine

• Guanine

• Thymine

• Uracil

What determines the genetic code in DNA?

• The structure of the DNA double helix.

• The order (sequence) of the nitrogen bases.

• The number of chromosomes in a cell.

• The type of organism it belongs to.

What is the role of tRNA in protein synthesis?

• tRNA transports amino acids to the ribosome during translation.

• tRNA synthesizes proteins from amino acids.

• tRNA acts as a catalyst in the formation of peptide bonds.

• tRNA carries genetic information from DNA to the ribosome.

What is one key difference between DNA and RNA?

• RNA contains the base Uracil.

• DNA contains the base Thymine.

• RNA is double-stranded while DNA is single-stranded.

• DNA is found in the cytoplasm while RNA is found in the nucleus.

What sugar is found in RNA?

• Glucose

• Fructose

• Ribose

• Sucrose

What is the difference between DNA and RNA in terms of structure?

• DNA is single-stranded, while RNA is double-stranded.

• DNA is double-stranded, while RNA is single-stranded.

• Both DNA and RNA are double-stranded.

• DNA and RNA have identical structures.

What is the process called when DNA makes an exact copy of itself?

• Transcription

• Translation

• Replication

• Mutation

What are the building blocks of DNA?

• Amino Acids

• Nucleotides

• Fatty Acids

• Monosaccharides
