The life cycle of an organism in the model begins with a single reproductive cell. In each round, all cells divide and the daughter cells each develop into one of the different cell types. Once the ...

Researchers from Japan and France have successfully reconstituted the development of mouse egg cells, known as oocytes, from ...

Scientists believe that they are an important step nearer to success in creating an artificial egg from the combination of the nucleus of a somatic cell and an oocyte which has had its DNA ...

The cells involved with human reproduction, however, carry only half after division occurs. In this step-by-step explanation, learn about mitosis and meiosis, the two types of cell division.

The reproductive cell of an organism; typically contains half or a reduced number of chromosomes compared to a somatic cell. In mammals, gametes are haploid cells that fuse to form a diploid zygote.

In genetics and developmental biology, somatic cell nuclear transfer (SCNT) is a laboratory technique for creating an ovum with a donor nucleus. It can be used in embryonic stem cell research, or ...

Scientists Found Cells That Defy the Rules of Reproduction—and Could Change Biology Mitosis is no longer just what you learned in high school. By Elizabeth Rayne Published: May 06, 2025 1:00 PM EDT ...

A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information. ... Sexual reproduction. Video Sexual reproduction. 4 of 6. 0:46 ...

A simple mechanism could underlie the growth and self-replication of protocells - putative ancestors of modern living cells - suggests a study publishing September 3 in Biophysical Journal.

From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body's typically efficient DNA repair machinery and potentially affecting our health ...

Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information.
