Measles has an incubation period of between three and 21 days. This is the time period between when a child becomes infected with the measles virus and when symptoms develop. Usually, measles has a typical rash but other viral exanthems (widespread rash) are similar or eczema and allergic skin rash.
The centromere is A. a protein composed of 8 subunits that binds to DNA. B. an A-T-rich region of the chromosome which may be bound by kinetochores. C. proteins that help pull apart sister chromatids at the telomeres D. the name given to a specific short (about 10 bases long) region of G-C rich DNA... show more The centromere is A. a protein composed of 8 subunits that binds to DNA.
Compaction of the duplicated chromosomes during cell division (mitosis or meiosis) results either in a four-arm structure (pictured to the right) if the centromere is located in the middle of the chromosome or a two-arm structure if the centromere is located near one of the ends.t is not usually found on its own, but rather is complexed with many structural proteins called histones as well as associated transcription (copying of genetic sequences) factors and several other macromolecules. Two sister chromatids (half a chromosome) join together at a protein junction called a centromere.
