This is literally an ancient, microbiological factory.
- An RNA template strand comes out of it. Each rung of the ladder is called a base pair and there are about 3 billion base pairs that make up the genome, 30,000 genes and each cell have 23 pair of chromosomes. They thread around a spool as in torsion.
- Transcription factors bind open DNA and can recruit other proteins such as enzymes.
- RNA polymerase; DNA reads and transcribes DNA into RNA.
- The single strand RNA copies the A, C, T, and G of the mRNA
- It carries it out of the nucleus to the ribosome for the production of the particular protein that this gene codes for.
- There can be millions of ribosomes in a typical eukaryotic cell
- These complex cells use the RNA copy of the gene for info. to assemble amino acid building blocks into the 3D proteins that are essential for life. The ribosome is composed of one large and one small subunit that assembles around the mRNA which then passes through the ribosome like a computer tape.
- The amino acid building blocks are carried into the ribosome attached to SPECIFIC transfer RNA. They are attached to the glob of tRNA.
- The small subunit of the ribosome positions the mRNA so that it can be READ in groups of 3 letters known as a codon.
- Each codon on the mRNA matches a corresponding anticodon on the base of a transfer RNA molecule.
- The larger subunit of the ribosome removes each AA and joins it onto the glowing protein chain.
- As the mRNA is ratcheted through the ribosome the mRNA sequence is translated into an AA sequence (the Tzolkin themeplexes)
- There are 3 locations inside the ribosome designated A, P, and E site
- The addition of each AA is a 3-step cycle.
- #1. RNA enters the ribosome at the A site and is tested for a codon, anticodon, match with the mRNA
- #2. If there is a match the tRNA is shifted to the P site and the AA it carries is added to the end of the AA chain.
- The mRNA is also stuck on 3 nucleotides or 1 codon.
- #3-the spent tRNA is moved to the E site and then ejected from the ribosome to be recycled.
- 6 feet of DNA fits in the nucleus of every cell of an organism.
- In the helicase, it’s copied backward. It moves as fast as a jet engine looping and coiling leading to chromosomes.
- Then comes the KINETICORE. It’s a crazy, universal operation with its microtubule fibers.
- Chromatin is called the tightly packed cell
- Then it’s a chromatid
- Then it’s a chromosome
- Then it’s a nuclear pore and has a nuclear membrane gateway in the cell. The membrane breaks down.
