Study Notes
RNA and DNA
- Ribonucleic Acid (RNA) is a nucleic acid carrying instructions for protein production from the nucleus to the cytoplasm.
- Transcription is the process of making mRNA from RNA.
- Translation is the process of making a protein from RNA.
- Mutations are changes in the nucleotide sequence of a gene.
- Proteins are created with RNA's assistance.
- RNA is a single-stranded molecule, unlike double-stranded DNA.
- RNA contains uracil (U) in place of thymine (T) found in DNA.
- mRNA is the first step in protein synthesis.
- There are three types of RNA: mRNA, tRNA, and rRNA. These RNA types work together to create proteins.
Causes of Mutations in RNA
- Exposure to X-rays
- Exposure to ultraviolet light
- Exposure to certain chemicals
- Exposure to radioactive materials
Types of RNA Mutations
- Insertion: adding one or more nitrogen bases to the DNA sequence.
- Deletion: removing one or more nitrogen bases from the DNA sequence.
- Substitution: replacing one nitrogen base with a different one.
Results of Mutations
- Mutations can alter proteins, potentially changing traits or causing genetic disorders.
- Not all mutations negatively impact the organism; some have no effect or even benefits.
DNA vs. RNA
- DNA:
- Double-stranded
- Deoxyribose sugar
- Contains the genetic material
- Found in the nucleus
- Contains Thymine (T)
- RNA:
- Single-stranded
- Ribose sugar
- Contains proteins
- Found in the cytoplasm
- Contains Uracil (U)
