  1. The genetic code & codon table (article) | Khan Academy

    Decoding messages is also a key step in gene expression, in which information from a gene is read out to build a protein. In this article, we'll take a closer look at the genetic code, which …

  3. Intro to gene expression (central dogma) - Khan Academy

    During translation, the nucleotides of the mRNA are read in groups of three called codons. Each codon specifies a particular amino acid or a stop signal. This set of relationships is known as …

  4. Gene expression and regulation | AP®︎/College Biology | Khan …

    Understand how the genetic code directs translation from mRNA to protein. Explore the central dogma of gene expression and the role of ribosomes in building polypeptides.

  5. Overview of transcription - Khan Academy

    For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some …

  6. The genetic code (article) | Translation | Khan Academy

    How are the instructions for building a protein encoded in DNA, and how are they deciphered by the cell? In this article, we'll take a closer look at the genetic code, which allows DNA and RNA …

  7. The genetic code (article) | 3rd quarter | Khan Academy

    Course: SHS Biology 2 > Unit 1 Lesson 3: Genetics: Central dogma ... Replication Transcription and mRNA processing Overview of transcription

  8. Stages of transcription: initiation, elongation & termination (article ...

    In eukaryotes like humans, transcription termination happens differently depending on the type of gene involved. Here, we'll see how termination works for protein-coding genes.

  9. Types of RNA (article) | Khan Academy

    Mutations or defects in snRNAs or their associated proteins can lead to improper splicing, which is linked to various genetic diseases, such as spinal muscular atrophy.

  10. Early experiments on the genetic code - Khan Academy

    This experiment was an early step in the process of deciphering the genetic code, which was completed in 1966 when researchers identified the codons for all twenty amino acids.
