Study Notes
Transcription and Translation Overview
- mRNA is synthesized during transcription, which occurs in the nucleus.
- DNA is also located within the nucleus, serving as the template for mRNA formation.
Role of RNA Types
- mRNA functions to carry the genetic information from DNA to ribosomes for protein synthesis.
- rRNA, or ribosomal RNA, is a structural component of ribosomes, essential for protein assembly.
- RNA contains uracil (U) in place of thymine (T), which is found in DNA.
Protein Synthesis
- Proteins are composed of amino acids, which are linked together during translation at the ribosome.
- tRNA (transfer RNA) has crucial roles in translation, utilizing anticodons to pair with mRNA codons and delivering the appropriate amino acids.
Locations of Key Processes
- Transcription occurs in the nucleus, where the DNA sequence is converted into mRNA.
- Translation takes place in the cytoplasm, where ribosomes read the mRNA to build proteins.
tRNA Functions
- tRNA is responsible for attaching amino acids to form polypeptide chains, which eventually fold into functional proteins.
- tRNA resides primarily in the cytoplasm, facilitating the transport of amino acids to ribosomes.
Mobility of RNA
- RNA can exit the nucleus after its synthesis, in contrast to DNA, which remains in the nucleus.
