DNA binds to silica because of the strong electrostatic interactions between the negatively charged phosphate groups in the DNA backbone and the positively charged surface of silica. This attraction allows DNA to adhere to silica surfaces, making it useful for various applications in biotechnology and research.
Transcription factors bind to specific DNA sequences called enhancers and promoters to regulate gene expression.
ATTCG signify adenine (A), thymine (T), cytosine (C) and guanine (G). The bonding pairs are AT, GC when DNA replicates. Therefore the fragment ATTCG will bind to TAAGC.
There are basically two types of enzymes that can bind to DNA and copy it. The DNA polymerase and the RNA polymerase. The RNA polymerase, which copies DNA into RNA, will only bind to single stranded DNA, in other words areas of the DNA where the nitrogen bases holding the two strands of nucleotide units together have been separated. On the other hand the DNA polymerase that copies DNA into DNA will only bind to DNA that is double stranded. So in lies the dilemma. To make a copy of the DNA the DNA polymerase is use, but it will not bind to single stranded DNA so there is no way to make a DNA primer using aDNA polymerase, but the RNA polymerase will bind to single stranded DNA and there for can be used to make a small RNA primer on the open strands of DNA. Now the DNA polymerase has place that is double stranded and can attach and start copying the DNA.
Enhancers bind to specific regions of DNA within the cell to regulate gene expression.
RNA polymerase binds to the DNA at a specific region called the promoter to initiate transcription.
A adenine (A) nucleotide will bind to thymine (T) nucleotide in parental DNA through hydrogen bonding.
Transcription factors bind to specific DNA sequences called enhancers and promoters to regulate gene expression.

Readily bind to complementary chains of DNA. Thus, pieces of DNA that have been cut with the same restriction enzyme can bind togeher to form a new sequence of nucleotides.

Transcription factors.
bind repressor proteins to inhibit the start of transcriptions
Reactants: (dNTPs, template DNA (to be amplified), primers(bind to DNA to begin elongation of strand), DNA Polymerase (elongate DNA), & MgCl2) in buffer + H2O
Enhancers bind to specific regions of DNA within the cell to regulate gene expression.
