  • Genomic Analyses
    Technique using DNA sequence information to infer protein sequences, offering speed, efficiency, and comprehensive data compared to direct methods.
  • Direct Protein Sequencing
    Approach for determining protein sequences from isolated samples, capable of identifying unknown proteins and modified amino acids.
  • Tandem Mass Spectrometry
    Analytical method for direct protein sequencing that detects amino acid modifications and identifies unknown protein samples.
  • Edman Degradation
    Classic direct sequencing technique for determining amino acid order in proteins, used on purified protein samples.
  • DNA Sequencing
    Process of determining nucleotide order in DNA, enabling derivation of protein sequences via the genetic code.
  • Amino Acid Sequence
    Linear arrangement of amino acids in a protein, deduced from nucleotide sequences using the genetic code.
  • Nucleotide Sequence
    Ordered series of nucleotides in DNA or RNA, serving as the template for protein sequence determination.
  • Genetic Code
    Set of rules mapping mRNA codons to specific amino acids, essential for translating nucleotide sequences into proteins.
  • Codon
    Triplet of nucleotides in mRNA specifying a particular amino acid during translation.
  • mRNA
    Messenger molecule transcribed from DNA, carrying genetic information for protein synthesis.
  • Transcription
    Cellular process converting DNA coding sequences into mRNA, replacing thymine with uracil.
  • Translation
    Process decoding mRNA codons into a sequence of amino acids, forming a peptide.
  • Peptide
    Short chain of amino acids produced during translation, representing a segment of a protein.
  • Chemically Modified Amino Acid
    Residue altered post-translationally, detectable by direct sequencing but not by genomic analyses.
  • DNA Coding Sequence
    Segment of DNA containing information for protein synthesis, transcribed into mRNA for translation.
