Write a paragraph explaining how nucleic acids and proteins work together to provide instructions for the structures and functions of an organism.

Nucleic acids are responsible for the transfer of genetic information from one generation to the next. The two type of nucleic acid are DNA and RNA.  When a cell divides, its DNA is copied and passed from one cell generation to the next generation. RNA is essential to the synthesis of proteins.

Cell have different regulatory proteins like enzymes and some trans acting elements that attached to the cis acting elements of DNA and help its trancrption and translation each DNA has specific arrangment of nucleotides according to which RNA is produced which instruct ribosomes to form specific protein which will perform specific function in organism or play structural role
hope this helps

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
