Study Notes
tRNA (Transfer RNA)
- Delivers amino acids to ribosomes for polypeptide chain assembly.
- Contains anticodons that pair with mRNA codons.
- In RNA, thymine (T) is replaced with uracil (U).
mRNA (Messenger RNA)
- Serves as a copy of DNA, moving from the nucleus to the cytoplasm.
- Carries genetic information required for protein synthesis to ribosomes.
- Contains codons; also uses uracil instead of thymine.
rRNA (Ribosomal RNA)
- Constitutes the building blocks of ribosomes.
- Plays a crucial role in interpreting the information encoded in mRNA.
DNA (Deoxyribonucleic Acid)
- Contains all genetic information and serves as a template for protein synthesis.
- Undergoes transcription to produce mRNA for use in protein synthesis.
Transcription in Protein Synthesis
- Involves copying information from DNA to mRNA, directing the synthesis of proteins on ribosomes.
RNA Characteristics
- RNA is single-stranded.
- Uses uracil to bind with adenine.
- Comprises ribose sugar.
DNA Characteristics
- DNA is a double-stranded helix.
- Utilizes thymine to bind with adenine.
- Contains deoxyribose sugar and only exists in the nucleus.
Comparison of DNA and RNA
- Both DNA and RNA are made up of long chains of nucleotide units.
- RNA is found in both the nucleus and cytoplasm, whereas DNA is exclusively in the nucleus.
Types of Nucleic Acids
- There is one type of DNA.
- There are three types of RNA: mRNA, tRNA, and rRNA.
