my assigned organism is Naked mole rat (Heterocephalus glaber). please type it. The first step in understanding how information is passed from one generation to the next is understanding how cells divide, particularly how the DNA is passed on to the resulting cells. In this discussion, you will describe the life cycle of an animal or plant of your choosing. The animal or plant you choose must have a sexual life cycle (although it may also have an asexual life...

The purpose of interphase of a cell cycle is:
A
to divide itself in half in order to facilitate growth and/or
reproduction
B
to produce gametes
C
the 'living' phase of the cell, in which the cell obtains
nutrients, grows, reads its DNA, and conducts other "normal" cell
functions
D
to facilitate repairs from viruses and bacteria

2. A diploid cell contains two pairs of chromosomes, which we will call 1 and 2. Assume chromosome! is clearly larger than chromosome 2. Each chromosome pair contains a maternal and a paternal member (e.g. 1 and 1 & 2 and 2"). An allele called G is localized to 1" whereas an allele called g is on chromosome 1P. Allele R is localized to 2m whereas alleler is localized to 2. Using these designations and clearly drawn and labeled chromosomes,...
