What cell in the body doesn't have a nucleus when it is mature?
Red Blood Cells (erythrocytes) don't have nuclie when they are mature, the same thing applies to platelets (thrombocytes).
Corralaries: 1. You can't clone a human being from a red blood cell. (Even if we knew how to clone human beings :) )2. You can't do genetic test that depend on the genome using a red blood cell. (You can do genetic test based on microsomal RNA since the microsomes are intact and weren't part of the cell's nucleus to begin with.)
Mature red blood cells do not have nucleus in them. Nucleus contains the chromosomes. With out the chromosomes, you can not have cell division, in your body. ( You have about 25 trillion red blood cells in your body. You have about 100 trillion cells, in your body. That means one forth cells in your body can not undergo cell division.)
What nucleus is removed from a body cell of one organism and is palced in an egg cell that has had its nucleus removed?
The nucleus controls the cell. It is like the brain of the cell. Another way to put it is that the nucleus is like the control panel of the cells in your entire body. If that^ doesn't make sense then think of the nucleus as your brain. The cell is like your body. The brain( nucleus) controls your body's movements and reactions to certain things that do not include love.
A (proto)typical neuron contains three parts: a cell body, an axon, and a tree of dendrites. The cell body is also called the soma, which comes from the Latin for "body". Among many important tasks, the cell body houses the nucleus and most of the other cytoplasmic organelles. For this reason, yet another name for the cell body is the perikaryon, which comes from the Greek for "around the nut", where "nut" refers to the…
