Proteins Synthesis Notes

If DNA's shape is altered that can't function properly. RNA is more versatile so changing the shape improvements the function, which is desired. Any form of RNA could become another. 3 shapes/functions of RNA: -mRNA: messenger (linear_____)

-rRNA: ribosomal (large and such as a globe) Even more stable than mRNA. -tRNA: transfer (shaped like t) If you trim this it becomes mRNA. Hydrogen Bonds ……………………………….

Protein Synthesis Overview- Two Processes:

Transcription- synthesis of mRNA beneath the directions of DNA Translation- is the genuine decoding in the mRNA into a polypeptide. Occurs in ribosome's of cytoplasm and hard ER. (Ribosome's don't do anything but house). ---To generate proteins we all reassemble aminoacids found in meat, beans, seafood, nuts, ect; Triplet Code: codon- a series of three bottom pairs that code pertaining to an amino acid. DNA polymerase adds facets and is aware when to stop when it visits the terminator. The path DNA replicates is 3' (antisense strand) to 5' (sense strand) on parent and 5' to 3' on fresh. RNA digesting is like an editor. Exons are the parts of mRNA which can be kept (codons). Introns happen to be what is unneeded so are removed; they no longer make proteins. Caps and Tails happen to be protection; they may be like helmets and shoes or boots. DNApre-RNARNA processingRNA mRNA is created in the center during pre-mRNA AUG is a start codon; Stop codons: UAU, UAA, UGA.

Changement Notes

Mutation- is a everlasting change in organism's nucleic stomach acids (DNA/RNA). They might be results of mistakes in replication or perhaps transcription. Mutagens are chemicals that cause mutations (smoking, UV radiation) Two degrees of Mutations: chromosomal level and point level.

Chromosomal Level: Large variations involving the complete chromosome (or large sections of them) and are also almost never useful. Four types: * Duplication- Parts of a chromosome are made too many occasions * Translocation- Two nonhomologous chromosomes change information. (Eye color and height happen to be...
