This activity is aimed at helping students understand protein synthesis with words.
Translation: Making Protein Synthesis Possible - …
The genetic material making up genes is composed of deoxyribose nucleic acid (DNA). DNA has several properties that enable it to function as genetic material; it is able to (1) direct the synthesis of copies of itself (replicate itself), (2) store information that directs protein synthesis, and (3) direct the synthesis of structural and regulatory proteins. DNA is composed of nucleic acids. Therefore, appreciation of the structure of nucleic acids and DNA, and the process of protein synthesis are essential prerequisites to the understanding of control of cellular activity, drug action, and various disease processes.
The three codons, UAA known as ochre, UAG as amber and UGA as opal, that do not code for an amino acid but act as signals for the termination of protein synthesis.
A regulatory protein that binds to DNA and affects transcription of specific genes.

Initiation: RNA polymerase (enzyme) attaches to the promoter site to start RNA synthesis
Step One toward making a protein -- DNA is "transcribed" to RNA.
Translation: mRNA to Protein
mRNA leaves the nucleus and goes into the cytoplasm
Transcription & Translation
DNA is the map for building proteins in the body.
Ribonucleic Acid -- it has a ribose sugar and uses the same bases as DNA EXCEPT it replaces Uracil for Thymine.
RNA makes a copy of the DNA strand in order to transport the "code" out of the nucleus to the ribosome (site of protein synthesis).

Consistent symbols are used in both and the mammalian molecular model animations. Species-specific forms of the gene and its protein product PER are essential components of the negative feedback loop that regulates circadian rhythms. The regulatory enzyme doubletime is similar to the mammalian casein kinase 1 epsilon enzyme. The transcription factors that turn on gene transcription in (CYCLE and CLOCK) are close relatives of gene transcription factors in mammals (BMAL1 and CLOCK). (BMAL1 is homologous to CYCLE; the same molecule in different organisms often has a different name.) While cryptochrome is an essential molecular regulator for both and mammalian circadian rhythms, its function is quite different in these two organisms. Cryptochrome in is directly responsive to light input; light can pass through the exoskeleton of and enter neurons, where it produces a conformational change in cryptochrome. This activated cryptochrome then effects the degradation of TIM proteins in the nucleus. In contrast, the gene in mammals acts in concert with the gene in circadian rhythm regulation through the negative feedback loop. An active area of research is the examination of how light affects mammalian circadian clock genes.
Messenger RNA (mRNA) is a mature, copy of a gene that describes the exact sequence in which amino acids should be bonded together to form a protein. Transfer RNA (tRNA) molecules are responsible for picking up particular amino acids and transferring them to the ribosomes for assembly into polypeptides. Each tRNA molecule contains a triplet nucleotide sequence that can base-pair with a codon on the mRNA. This triplet nucleotide sequence on tRNA that is complementary to the codon of mRNA is called an anticodon. Ribosomal RNA (rRNA) is used in the manufacture of ribosomes where mRNA and tRNA come together in the synthesis of proteins.

Three Stages of Transcription
Once the RNA polymerase binds to the promoter, the DNA strands unwind, and the polymerase initiates RNA synthesis at the start point of the template strand.
A collection of proteins called transcription mediate the binding of RNA polymerase an the initiation of transcription.

Explain important scientific principles through the animations. For example, the biological clocks animations can be used to demonstrate the fundamentals of transcription and translation.
The synthesis of proteins from RNA is known as translation
DNA transcription is the process of making a single strand complementary RNA copy of DNA. Data is copied from the DNA to the RNA with the aid of the enzyme RNA polymerase. Using this process, the genetic information stored in the DNA is carried in the form of RNA to other parts of the cell. In eukaryotic cells a gene begins with a promoter region and an initiation code and ends with a termination code. However, the intervening gene sequence contains patches of nucleotides that have no meaning. If they were used in protein synthesis, the resulting proteins would be worthless. Eukaryotic cells prune these segments from the mRNA after transcription. RNA polmerase synthesizes a strand of pre-mRNA that initially includes copies of the meaningful mRNA coding sequences (exons) and the meaningless mRNA coding sequences (introns). Soon after its manufacture, this pre-mRNA molecule has the meaningless introns clipped out and the exons spliced together in the final version of mature mRNA
