The human body is made up of billions of cells. These cells grow and divide through a process called cell division. There are ...

The purpose of this paper is to describe still another type of sex-chromosome mosaic hitherto unreported, to discuss the possible mode of origin of such mosaics and to consider some of their ...

If the cells didn't have half, a fertilized egg would contain 92 chromosomes and be untenable. Meiosis, a type of cell division specific to reproduction, avoids this by halving the number of ...

Each of the 23 chromosome types has a unique banding pattern. (A chromosome pair has identical banding.) In fact, scientists can identify a chromosome based solely on its banding pattern.

One group of three chromosomes, called group D, was examined in more detail. Drets and Shaw wanted to determine whether the number of types of G-banding patterns was the same as the number of ...

Two types of condensin protein complexes enable this process. To understand how this looping eventually gives rise to rod-shaped chromosomes, the researchers built a computational model based on ...

and he denoted these categories Type A and Type B (Table 1). Table 1: Chromosome Counts in the Somatic Cells of Several Type A and Type B Species As illustrated in Table 1, the somatic cells from ...

A study led by bioengineers at the University of California San Diego sheds new light on how a type of heart valve ... can be traced to a gene on the Y chromosome. The discovery, published in ...
