Select the correct answer. what are the basic building blocks of dna and rna? a. nucleotides b. phosphorous c. proteins d. sugar

Each RNA nucleotide consists of three parts: a sugar, a phosphate group, and a nitrogen-containing base. The four RNA bases are adenine, uracil, guanine, and cytosine—often referred to as A, U, G, and C. RNA shares three bases in common with DNA: adenine, guanine, and cytosine. Instead of uracil, DNA contains thymine.

Nucleotides are the macromolecular building blocks of DNA and RNA. ... The nitrogenous base that makes up the nucleotide can vary between adenine, guanine, cytosine, thymine (in DNA) and uracil (in RNA). Furthermore, the sugar can also vary between deoxyribose in DNA and ribose in RNA.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
