Amoeba Sisters DNA vs RNA Worksheet Answer Key
The Amoeba Sisters DNA vs RNA worksheet provides an overview of the differences between DNA and RNA. This answer key provides the correct answers to the worksheet questions, highlighting the key points of each molecule.
Key Differences between DNA and RNA
- Structure:DNA is a double-stranded molecule, while RNA is a single-stranded molecule.
- Function:DNA stores genetic information, while RNA is involved in protein synthesis.
- Location:DNA is found in the nucleus of cells, while RNA is found in both the nucleus and the cytoplasm.
- Stability:DNA is more stable than RNA due to its double-stranded structure.
DNA Structure and Function
DNA, or deoxyribonucleic acid, is a molecule that contains the instructions for an organism’s development and characteristics. It is a double-stranded molecule composed of nucleotides, which are made up of a sugar molecule, a phosphate molecule, and a nitrogenous base.
Role of DNA
- Stores genetic information
- Transmits genetic information from parents to offspring
- Directs the synthesis of proteins
DNA Replication
DNA replication is the process by which DNA makes a copy of itself. This process occurs before cell division, ensuring that each new cell receives a complete copy of the genetic information.
RNA Structure and Function: Amoeba Sisters Dna Vs Rna Worksheet Answer Key
RNA, or ribonucleic acid, is a single-stranded molecule that is involved in protein synthesis. It is composed of nucleotides, which are made up of a sugar molecule, a phosphate molecule, and a nitrogenous base.
Types of RNA, Amoeba sisters dna vs rna worksheet answer key
- mRNA (messenger RNA):Carries genetic information from DNA to the ribosomes, where proteins are synthesized.
- tRNA (transfer RNA):Transfers amino acids to the ribosomes during protein synthesis.
- rRNA (ribosomal RNA):Forms the structure of ribosomes, where protein synthesis occurs.
Role of RNA in Protein Synthesis
RNA plays a crucial role in protein synthesis by transferring genetic information from DNA to the ribosomes, where proteins are assembled.
Comparison of DNA and RNA
| Characteristic | DNA | RNA |
|---|---|---|
| Structure | Double-stranded | Single-stranded |
| Function | Stores genetic information | Involved in protein synthesis |
| Location | Nucleus | Nucleus and cytoplasm |
| Stability | More stable | Less stable |
