1. Mis on sidumissait? Mille poolest ta a) sarnaneb, b) erineb TATAbox-
st?
2. Sidumissait - regioon (valgus, DNA-s jne), mis on spetsiifiliseks
seostumiseks teistele molekulidele, ioonidele. It is a region on a protein,
DNA, or RNA to which specific other molecules and ions -- in this context
collectively called ligands, or more specifically, protein ligands -- form a
chemical bond.
3. TATA-box is a DNA sequence (Cis-regulatory element) found in the
promoter region of most genes in eukaryotes. It is the binding site of either
transcription factors or histones and is involved in the process of
transcription by RNA polymerase. It has the core DNA sequence 5'-
TATAAA-3' or a variant, which is usually followed by three or more
adenine bases and has been highly conserved through evolution. The TATA
box is usually located 25 base pairs upstream to the transcription site.
