    Study Notes

    Protein Synthesis

    • Protein formation usually takes place in the ribosomes.
    • mRNA (messenger RNA) sequence is composed of codons, which are triplets of nucleotides that code for amino acids.

    mRNA Structure and Function

    • The first step in protein production is transcription, where DNA is transcribed into mRNA.
    • mRNA transcripts are produced from a DNA template through the process of transcription.
    • The mRNA sequence composition includes a sequence of codons that dictate the amino acid sequence of a protein.

    Codons and Protein Synthesis

    • Codons represent specific amino acids or stop signals during protein synthesis.
    • The process by which cells synthesize proteins is called gene expression, which involves transcription and translation.

    Importance of Gene Expression

    • Studying gene expression is important in disease diagnosis, as changes in gene expression can contribute to disease development and progression.
