<span>The answer is chromatin. Chromatin is composed
of DNA wound up in protein complexes called histones to form nucleosomes. At the
start of mitosis or meioses, chromatin is folded up into a 30nm fibre which is sequentially
folded up to 1400nm fibres .</span>
The genes involved in pattern formation and organization of body parts are called homeobox genes, which are a large family of similar genes.
The h<span>omeobox genes direct the formation of many body structures during early development of the embryo. </span>

Second, if the earth doesn't recieve sunshine for a long time, it will freeze
Answer:
Characterization of exosomes has become a topic of interest in medical research and molecular biology because it can provide very valuable information for early detection, disease monitoring and development of effective treatments against cancer and autoimmune diseases. Exosomes are known as one type of secreted membrane vesicles that are responsible for intercellular communication by providing means for intercellular exchange of proteins, lipids, mRNA, miRNA and DNA, contributing to intercellular communication in relevant biological processes, playing an important role in the development of several diseases, and specifically, modulating cancer microenvironment and the immune response. Exosomes and its contents also have emerged as non‐invasive biomarkers for various diseases. Exosomes composition and quantity may be directly related to the pathological state of the patient, so the characterization of exosome could be of great relevance for diagnosis.
