Beschreibung

Gene Sequence of DNA or RNA which codes for molecule that has function. Product include: SiRNA, rRNA, miRNA, tRNA, mRNA. Gene Expression, information from a Gene is used in the synthesis of functional gene products. Molecular Levels Level one:1-DNA, 2-TranscriptionLevel Two - 1-RNA, 2-Translation, 3-RNACommon transcription factor motifs Zinc finger Helix-loop-helix (HLH) Leucine zipper (LZ) HMG box (high mobility group ) Shared feature Structurally stable framework Specific DNA recognizing sequences are correctly positioned, Repression of Transcription Cells also possess negative regulatory elementsMechanisms: Binding to promoter elements. Blocking assembly of the preinitiation complex. Inhibiting binding or functioning of transcriptional activators. Modifying DNA and its interaction with nucleosomes. Some transcription factors activate some genes and repress others.
