Which of the following is a property of bases?

B. Feels slippery

This is most likely the Chemical Properties of Bases

The Chemical Properties of Bases include:

- Bases change the colour of litmus from red to blue.

- They are bitter in taste.

- Bases lose their basicity when mixed with acids.

- Bases react with acids to form salt and water. This process is called Neutralisation Reaction(Read).

- They can conduct electricity.

- Bases feel slippery or soapy.

- Some bases are great conductors of electricity.

- Bases like sodium hydroxide, potassium hydroxide, etc are used as electrolytes.

- Alkalis are bases that produce hydroxyl ions (OH-) when mixed with water.

- Strong alkalis are highly corrosive in nature whereas other alkalis are mildly corrosive.

- The pH value of bases ranges from 8-14.
Alkalis and ammonium salts produce ammonia.

- Hydrogen gas is evolved when metals react with a base.

- Bases are classified on the basis of strength, concentration and acidity.

- The different kinds of acids are strong base acid, weak base acid, concentrated base, dilute base, monoacidic base, diacidic base and triacidic base.

PLEASE HELP!! (I will mark brainiest) (REAL ANSWERS ONLY PLEASE!)
Inessa [10]

The phosphate group of one nucleotide bonds covalently with the sugar molecule of the next nucleotide, and so on, forming a long polymer of nucleotide monomers. The sugar–phosphate groups line up in a “backbone” for each single strand of DNA, and the nucleotide bases stick out from this backbone. The carbon atoms of the five-carbon sugar are numbered clockwise from the oxygen as 1′, 2′, 3′, 4′, and 5′ (1′ is read as “one prime”). The phosphate group is attached to the 5′ carbon of one nucleotide and the 3′ carbon of the next nucleotide. In its natural state, each DNA molecule is actually composed of two single strands held together along their length with hydrogen bonds between the bases.
