Chromosomes are made up ofgenes, meaning theanswer is c). Chromosomes are structures made up of condensed DNA, and within this DNA are special...
A chromosome carries the same complement of genes whether it is transmitted from the father or the mother, and most of these genes appear to be functionally the same. However, a small number of mammalian genes are functionally different depending on whether they were transmitted by the egg or ...
In a human cell that's busy doing its job—such as being a muscle cell, for example—the chromosomes are locked up in a cellular vault called the nucleus. The nucleus keeps the chromosomes—and the genes they contain— safe from outside interference. When a cell is ready to split into ...
Association of Types of Overlapping Genes with the Size of Chromosome in Human Genome Since the discovery of maize B chromosomes by Kuwada (1925), they have been intensively studied. Evolution of Maize Landraces in Southwestern China: Evidence from B Chromosomes "Beyond any one application, the pa...
Such events yield isodicentric Y chromosomes that contain two centromeres, two copies of some genes, and no copies of other genes (Figure 4B). The Y chromosome ``I wanted to show there were five or six Y chromosomes circulating,'' he says. Bloodstock Desk: People think were suddenly going...
(100,000 cells lined up to equal one meter), DNA must be tightly packaged to fit in the cell’s nucleus. At the same time, it must also be readily accessible for the genes to be expressed. During some stages of the cell cycle, the long strands of DNA are condensed into compact ...
Chromosomes X and Y do not make up a fully homologous pair. The X chromosome in humans is much longer than the Y chromosome and also contains many more genes. However, there is a short region on both the X and Y chromosomes, called the pseudoautosomal region (PAR), that allows the X ...

What other genes are on the Y chromosomes? Chromosomes are located in a nucleus in which of the following? Prior to supercoiling, what are chromosomes referred to as? What determines the heredity of the 46 chromosomes? What is the term that describes a cell with only one set of chromosomes...
diseases.The Nobel Assembly at Karolinska Institutet in Stockholm, Sweden, announced on Monday that the three Nobel Laureates won their award for the discovery of "how chromosomes are protected by telomeres and the enzyme telomerase".The genes that make up our genome are the blueprint of our ...
