Life takes shape with the motion of a single cell. In response to signals from certain proteins and enzymes, a cell can start ...

Now, researchers at MIT have discovered a way to manipulate these early cellular motions using light, providing a new tool to ...

The researchers observed that light activated the enzyme, causing predictable cell movements. For example, specific light ...

When a sperm cell fertilizes an egg, the resulting zygote has the genetic information from both cells but only cytoplasm—the substance that fills the cell—from the egg. That means that any of ...

As in telophase I, the cytoplasm of the cell will be concentrated in one of the two emerging cells. The resulting large cell will become an egg cell. The smaller cell will degenerate.

Cytoplasmic flows guide chromosome positioning during embryogenesis. During the first stages of animal embryo development, the egg cell undergoes multiple divisions without growin ...

They investigated the interaction of cytoplasm and chromosomes ... as a cellular process involving the fusion of an egg cell and a spermatozoan and the fusion of their nuclei.

Okay let's move on. An animal cell is made of three main parts a nucleus, cell membrane and cytoplasm, which holds the rest of its critical components. And it's so small you could actually fit 100 ...

In prokaryotes, the circular chromosome is contained in the cytoplasm in an area called ... Meanwhile, germ line cells, which go on to produce egg or sperm cells, are called haploid because ...
