How many chromosomes are there in each stage of mitosis in an animal like Drosophila?
What difference exists between the compaction of chromosomes during metaphase
versus interphase? Give at least one reason why this difference may be necessary.
The interphase is the part of the eukaryotic cell cycle that is most transcriptionally active. Gene regulation during this phase involves changes in the chromatin.
a) What is chromatin?
b) How can the chromatin structure change?

Give atleast one reason why this difference may be necessary.arrow_forwardThe term heterochromatin refers to heavily condensed regions of chromosomes that are largely devoid of genes.

None of these are TRUE Interphase chromosomes are loosely compacted, overlapping, and intertwined with each other within the nucleus. Radial loops in the condensing chromosome are formed due to interactions between 30 nm fibers and the scaffolding proteins of the nuclear matrix - producing the 300 nm fiber of the chromosome Interphase chromosomes are loosely compacted and do not associate with histones until the cell is preparing to divide. Interphase chromosomes are also known as euchromatin. Condensed, metaphase chromosomes are also known as heterochromatin.arrow_forward
