Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.
Answer:
Because the promoter region is initiation sites for transcription to occur.
Explanation:
Transcription is the first process of gene expression in both eukaryotic and prokaryotic cells. Transcription involves the synthesis of a complementary RNA strand from a DNA template. It is carried out by an enzyme called RNA polymerase which binds to the DNA molecule and adds nucleotides based on the sequence it reads on the DNA.
On the DNA molecule, are sequences of nucleotides which the RNA polymerase recognizes and binds to in order for the transcriptional process to start. These sequences are called PROMOTER regions. They are located upstream i.e. after initiation site, of the DNA. Without these promoter region, RNA polymerase cannot bind to the DNA molecule and hence transcription cannot occur.
PCR multiplies the DNA in 25 to 75 cycles
