5 Questions
Match the following cellular components with their association to RNA:
Nucleus = Site of RNA synthesis Mitochondria = Site of RNA translation Chloroplasts = Site of RNA degradation Ribosomes = Site of protein synthesis
Match the following RNA types with their cellular locations:
mRNA = Found in the nucleus and ribosomes tRNA = Found in the soluble part of the cytoplasm rRNA = Found in the mitochondria and chloroplasts snRNA = Found in the ribosomes and cytoplasm
Match the following RNA functions with their descriptions:
mRNA = Carries genetic information from DNA to ribosomes tRNA = Transfers amino acids to ribosomes rRNA = Participates in protein synthesis as part of ribosomes snRNA = Involved in RNA splicing and processing
Match the following cellular organelles with their RNA-related activities:
Ribosomes = Translate mRNA into protein Mitochondria = Synthesize RNA during energy production Chloroplasts = Regulate gene expression through RNA Nucleus = Process and modify RNA transcripts
Match the following RNA-related terms with their meanings:
Soluble part of the cytoplasm = Region where RNA is translated into protein Messenger RNA = Carries genetic information from DNA to ribosomes RNA synthesis = Process of creating RNA from DNA template RNA degradation = Process of breaking down RNA molecules
Study Notes
Gene Expression
- Gene expression involves two essential steps: transcription and translation
Transcription
- Occurs in the nucleus of eukaryotes
- Involves the synthesis of mRNA using the gene on the DNA molecule as a template
Translation
- Involves the synthesis of a polypeptide chain using the genetic code on the mRNA molecule as a guide
- Relies on the mRNA molecule as its template
RNA (Ribonucleic Acid)
- Found throughout the cell, including:
- Nucleus
- Mitochondria
- Chloroplasts
- Ribosomes
- Soluble part of the cytoplasm
- Types of RNA:
- Messenger RNA (mRNA)
