Which of these is what DNA and RNA are? * O A. lipids
O B. proteins
O C. nucleic acids
O D. carbohydrates

DNA and RNA are both examples of nucleic acids

They consist of a strand of nucleotides with a phosphate group, a 5′ sugar and a nitrogenous base.

Extra info: DNA and RNA molecules are polymers. DNA is double stranded, whereas RNA is single stranded.

The nucleotides of DNA can pair together by base pairing, creating a strand that is complementary to its pair

Various types of RNA exist which have roles in protein synthesis as well as regulation of cellular programmes by fine-tuning gene expression.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this

i have to report this, it doesn't relate to biology
