<span>Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.

Answer:
Gravity.
Explanation:
Gravity is what causes stuff to fall. It also keeps us on the ground, If there were no gravity, life wouldn’t exist as we know it today. Brainliest please! I need brainlest in order to keep answering questions!!
Biogeochemical cycles are important because they regulate the elements necessary for life on earth by cycling them through biological and physical aspects of the word.
The right answer is a surface glycoprotein.
The antigens of the non-self correspond to any substance foreign to the organism, identified as such by the immune system of our organism which produces an energetic defense. Antigens are usually proteins (more specifically glycoproteins) contained in cells or foreign bodies (red blood cells transfused, organs transplanted, bacteria, viruses), or present in the environment (pollen, mite droppings, cat hair , etc.).
Our body has its own antigens that allow it to have a "specific identity card" and will be recognized as foreign by other organizations. They are called "self antigens".
The statement above is TRUE.
RNA hydrolysis is a reaction in which a phosphodiester bond in the sugar phosphate backbone of RNA is broken, thus cleaving the RNA molecule.
This reaction is made possible in RNA because the ribose sugar in RNA has hydroxyl group at the two prime position.
