Document Summary
What would increase or decrease the amount of active protein that gets to final location. Activators and repressors binding to enhancers: post transcription. All need to be present to have transcription. Acetyl = promotes initiation of transcription by relaxing histone making them more accessible. Deactyl= demotes initiation of transcription tightens histone with dna. Inactivates transcription by hav methyl group places on cytosine the dna. Heterochromatin (dark spots) = tightly bounded= silenced gene. Tf are often highly regulated by external factors. Length of the poly-a tail gives yo idea of life. Long tail lasts for long time makes more protein more tim ribosomes to bind. After proteins are made needs to get to its locations. This requires cytoskeleton and motor proteins see section bellow. Gelsolin= cuts microfilaments response to high calcium: elongation control, stabilization control, capping proteins, cross-linking proteins, serving proteins. Need tim and tom to be ready to allow it to go into the matrix.
