BIO 3147 Lecture Notes - Lecture 5: Euchromatin, Chromosome, Nucleosome
Document Summary
One cell becomes different --> causes the neighbour to be different. Delta and notch, anchor vs ventral uterine cell. Promoter opens, more transcription factors can come in. Can be two or 5 or any number like that. Intergrates the exterior cytoskeleton and in the inner cytoskeleton. Some proteins can also affect factors like the wnt paracrine factor. Like fibers stopping factors from travelling very far. Case study where the bio-inks help grow hair follicles. Will help localize the factors near the cells. Bio-inks made from gels based on tissue from place you want to use the bio-ink for. One cell diploid and one cell no nucleus. Five different layers to play with to make different. Size of the genome a. b. c. d. Usually the more complex the organism, the bigger the gene. When open can use, when close-hetero, cannot use. Found on fully developed cells eg muscles cells iv. Enhancer decides whether the gene will be transcribed or not.
