Hello!
RNA in cells differs from DNA in that it is single-stranded and can fold up into a variety of structures.
RNA is the abbreviation for RiboNucleic Acid. It is a biological molecule that fulfills an important role by copying the information stored in the DNA (DeoxyriboNucleic Acid) and transporting it to the different proteins by folding into different shapes. Its name come from a Ribose molecule that is present in this single-stranded molecule.
Viruses don't have DNA, only RNA. They only replicate in the host's cells by copying their own RNA information.
Have a nice day!
The R group varies, and it is the carbon-phosphate backbone
Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection.
The atmosphere is also slightly heated by absorption of electromagnetic radiation from the Sun. The warm land and water radiates infrared, some of which is absorbed by the atmosphere, adding to its thermal energy. The remaining heat on the surface is sent out into space in the form of infrared radiation.
True, because if the world gets warmer, glaciers will melt, causing there to be more available water. If the world gets cooler, glaciers will form, causing there to be less available water.
