RNA is stranded. It leave the nucleus, unlike DNA. It still consists of , however the in the backbone of the strand is different than in DNA. The nitrogenous bases are different in RNA; instead of Thymine, Adenine now pairs with .

Explanation:

RNA is single-stranded. It does leave the nucleus, unlike DNA. It still consists of strands, however, the ribose in the backbone of the strand is different than in DNA.

The nitrogenous bases are different in RNA; instead of Thymine, Adenine now pairs with Cytosine.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
