Gene Expression

Gene Expression. Gene expression?. Biological processes, such as transcription, and in case of proteins, also translation, that yield a gene product. A gene is expressed when its biological product is present and active. Gene expression is regulated at multiple levels.

Gene Expression

Gene Expression. Cell Differentiation. Cell types are different because genes are expressed differently in them. Causes: Changes in chromatin structure Initiation of transcription RNA processing mRNA degradation Translation Protein processing and degradation. Operons.

Green Florescent Protein as a Marker for Gene Expression

Green Florescent Protein as a Marker for Gene Expression. Role of GFP in Aequorea victoria. Photoprotein aequorin stimulated by calcium ions Aequorin catalyzed to higher energy state: Apoaquorin 3 . Blue light released as Apoquorin relaxes to ground state.

Gene Expression

Gene Expression. The human genome contains about 20,325 protein-encoding genes - However, this represents only a small part of the genome Much of the human genome controls protein synthesis - Including the time, speed, and location. Proteins have diverse functions in the body.

Gene Expression

Gene Expression. Gene: contains the recipe for a protein. 1. is a specific region of DNA on a chromosome. 2. codes for a specific mRNA. mRNA: exits the nucleus and associates with ribosomes. 1. carries the code for a specific protein to the cytoplasm.

Gene Expression

Gene Expression. Review covering RNA Processing & Translation. Posttranscriptional ( RNA Processing). - Transcription has created a primary transcript (pre mRNA) that is not ready to be exported from the nucleus to the ribosome in the cytosol.
