RNA

What is the role of rRNA in protein synthesis?

• rRNA carries amino acids to the ribosome.

• rRNA forms the core of the ribosome's structure and catalyzes protein synthesis.

• rRNA is responsible for the transcription of DNA.

• rRNA helps in the folding of proteins.

What is the product of translation?

• Carbohydrates

• Lipids

• Proteins

• Nucleic Acids

Why is RNA considered a single-stranded molecule?

• RNA is typically double-stranded, which allows it to be more stable.

• RNA is typically single-stranded, allowing it to fold into various shapes and perform different functions.

• RNA is always found in a circular form, which is essential for its function.

• RNA can only exist in a linear form, which limits its capabilities.

What is the difference between transcription and translation?

• Transcription is the process of making proteins from mRNA, while translation is the process of making RNA from DNA.

• Transcription is the process of making RNA from DNA, while translation is the process of making proteins from mRNA.

• Transcription and translation are the same processes that occur in the nucleus.

• Transcription is the process of copying DNA into DNA, while translation is the process of making lipids from RNA.

What is the significance of the start codon in translation?

• It signals the beginning of protein synthesis.

• It determines the amino acid sequence of the protein.

• It acts as a termination signal for translation.

• It is involved in the folding of the protein.

The Process of creating RNA from DNA.

• Translation

• Replication

• Transcription

• Mutation

What are codons?

• Sequences of two nucleotides in DNA that correspond to specific proteins.

• Sequences of three nucleotides in mRNA that correspond to specific amino acids.

• Single nucleotides in RNA that determine the structure of proteins.

• Pairs of nucleotides in mRNA that regulate gene expression.

What is the role of the ribosome in protein synthesis?

• The ribosome is the site where mRNA is translated into a protein.

• The ribosome is responsible for DNA replication.

• The ribosome synthesizes lipids for cell membranes.

• The ribosome transports amino acids to the nucleus.

Carries the code for making a protein.

• tRNA

• rRNA

• mRNA

• DNA

What are the three types of RNA?

• mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA)

• DNA (deoxyribonucleic acid), mRNA (messenger RNA), and tRNA (transfer RNA)

• mRNA (messenger RNA), sRNA (small RNA), and rRNA (ribosomal RNA)

• tRNA (transfer RNA), rRNA (ribosomal RNA), and cRNA (complementary RNA)
