<li>Transcription factors are proteins that bind to DNA and regulate gene expression.</li>
<li>They can activate or repress gene transcription by binding to specific DNA sequences.</li>
<li>Transcription factors are crucial for controlling gene expression and coordinating cellular processes.</li>

<li>DNA microarrays (gene chips) are used to study gene expression on a large scale.</li>
<li>They consist of an orderly arrangement of thousands of DNA fragments or probes.</li>
<li>They can provide valuable information about patterns of gene expression in different tissues or under different conditions.</li>
