The correct answer is: a. A site in DNA that recruits the RNA Polymerase
Promoters are regions of DNA molecule located near the transcription start codons of genes, usually upstream on the DNA with the function to initiate DNA transcription. Promoters contain specific DNA sequences (e.g. TATA boxes) that are binding sites for the enzyme RNA polymerase and transcription factors that recruit RNA polymerase. Transcription factors can regulate gene expression and act as activators or repressors depending on sequences that attach to specific promoters.
True.
I know this because it happened to my family and friends families. Sorry if it’s wrong
Oh god, large question. My eyes hurt... Mitosis is the formation of 2 identical daughter cells (cell division). Mitosis have 5 phrases: interphase, prometaphase, prophase, metaphase, anaphase, telophase and cytokinesis. The chromosomes are duplicated during the cell life just before mitosis since mitosis states that it is the splitting of the cells so duplicating the chromosomes isn't actually mitosis but it is still important to mitosis. Anyway, in interphase, the nucleolus starts to disappear, the microtubule starts to form and the chromosomes start to condense. In pro metaphase, some of the microtubule connect to the centromere, the cell membrane fully disappear and the chromosomes finishes condensing. In metaphase, the chromosomes are pulled to the center of the cell via by the contraction of the spindles and 2 spindles are connected to each of the kinetochores. In anaphase, the chromatids are separated via by the spindles. In Telophase, the nuclear membrane reappears, the chromosomes un-condenses and the micro tubal breaks down. In Cytokinesis, the cell membrane in one cell breaks apart from the other cell forming 2 daughter cells or in plant cells, another cell wall is formed. (this process can differ fro each different organism)
