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 ...
1.A linear strand of DNA and associated proteins in the nucleus of eukaryotic cells that carries the genes and functions in the transmission of hereditary information. 2.A circular strand of DNA in bacteria and archaea that contains the hereditary information necessary for cell life. ...
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 ...
What are chromosomes made up of?The Chromosomes:Chromosomes are found in the nucleus of every cell from living things. They are the genetic material that gets replicated during the life cycle of a cell such as during the phase of cell division. When a cell divides, new cells are formed, ...
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 ...
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 ...
(T)]. In each chromosome, sequences of DNA make upgenesthat control or partially control a number of visible characteristics, known as traits, such as eye color, hair color, and so on. A single gene may have multiple possible variations or alleles. Analleleis a specific version of a ...
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...
The sex vesicle could thus ensure that these sex-determining genes are always main- tained on the sex chromosomes. This mechanism could then prevent the occurrence of gene combinations which might upset the normal balance for sex determination. 8. ORIGIN OF THE GIANT CHROMOSOMES There is very ...
