The false statement is: (a) Transcriptional regulators usually interact with the sugar–phosphate backbone on the outside of the double helix to determine which DNA sequence to bind.
Transcriptional regulator or factor is protein with the ability to control and regulate gene expression at the transcription level by binding to DNA. Transcriptional factors have domain-DNA-binding domain which contains structural motif that recognizes DNA and it is responsible for the attachment to specific DNA sequence. It usually binds to the DNA major groove (hydrogen bonding) because it is less degenerate than that of the DNA minor groove.
Transcriptional factors also contain trans-activating domain for the binding of other proteins and signal-sensing domain for the detection of external signals.
If your eyes are exposed to a microorganism, the first thing you should do is to <u>Flush your eyes with water for at least 10-15 minutes. </u>

- Proper eyelid cleanliness stops the bacterial buildup that leads to blepharitis and the potential for Demodex.
- Maintaining clean eyelids and lashes is also essential for safeguarding the many glands that line our eyelids and aid in the production of our tears.
- To allow the fluid to move across the eye, someone should flush their eye for 10 to 15 minutes while attempting to keep their eyes open.

Genetically modified (GM) foods are the ones came from organisms whose genetic material (DNA) are altered as they do not occur naturally. Food shortage, cost, variety can make people support the GM foods, while, religious beliefs, allergy, and worrying about the food can limit the support for these foods.
<h3>What are the characteristics of GM foods?</h3>
Genetically modified (GM) foods are those derived from organisms the ones genetic material (DNA) has been altered as they do not occur naturally.
Its characteristics are:
- More nutritious food.
- Less use of pesticides.
- Faster growing plants and animals.
- Disease- and drought-resistant plants.
As food shortage, cost, variety can make people support the GM foods, while, religious beliefs, allergy, and worrying about the food can limit the support for these foods.
Thus, the correct option is A.

Answer:
Proteins and phospholipids make up most of the membrane structure. The phospholipids make the basic bag, while the proteins are found around the holes and help move molecules in and out of the cell.
The way that you will easily deduce which one it is is that you'll see the mouth first instead of the anus because of the different ways of development.
