What do the regulatory regions found in a chromosome primarily regulate?
The expression of genetic regions
Are all regions in a particular biome located in one place?
no
How might x inactivation cause patchy hairiness on women who have congenital generalized hypertrichosis even though the disease causing allele is dominant?
Since one X chromosome in each cell is randomly inactivated at some point during development, a woman heterozygous for hypertrichosis would have varying regions of patchy hair if the alleles responsible for the trait were located on the X chromosome. Variation would look similar to the varied tortoise shell coat color pattern on female cats, where the presence of yellow and black (red and gold/blue and cream) is controlled by X chromosome inactivation.
What process helps make meiotic cells genetically different and occurs during prophase but not during prophase 2?
Th process of independent orientation of chromosomes while in their tetrad forms. But, the more important process that also happens in prophase I is the process of crossing over where chromosomes, male and female, exchange regions of the chromosomes, one with the other.
What are nine abdominopelvic regions and the location of each?
the 9 abdominopelvic regions are: 1 epigastric - located in the right upper quadrant 2 right hypochondriac - located in the right upper quadrant 3 umbilical - located centrally in the right/left quadrant 4 right lumbar - located in right lower quadrant 5 hypogastric located in right lower quadrant 6 right iliac - located in right lower quadrant 7 left hypochondriac - left upper quadranrt 8 left lumbar - left lumbar - left lower quadrant 9 left iliac - left lower quadrant
How many chromosomes do you have in a cell found in your elbow?
The X chromosome is one of the two sex chromosomes in humans (the other is the Y chromosome). The sex chromosomes form one of the 23 pairs of human chromosomes in each cell. The X chromosome spans about 155 million DNA building blocks (base pairs) and represents approximately 5 percent of the total DNA in cells. Each person normally has one pair of sex chromosomes in each cell. Females have two X chromosomes, while males have one X and one Y chromosome. Early in embryonic development in females, one of the two X chromosomes is randomly and permanently inactivated in cells other than egg cells. This phenomenon is called X-inactivation or Lyonization. X-inactivation ensures that females, like males, have one functional copy of the X chromosome in each body cell. Because X-inactivation is random, in normal females the X chromosome inherited from the mother is active in some cells, and the X chromosome inherited from the father is active in other cells. Some genes on the X chromosome escape X-inactivation. Many of these genes are located at the ends of each arm of the X chromosome in areas known as the pseudoautosomal regions. Although many genes are unique to the X chromosome, genes in the pseudoautosomal regions are present on both sex chromosomes. As a result, men and women each have two functional copies of these genes. Many genes in the pseudoautosomal regions are essential for normal development. Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. The X chromosome likely contains between 900 and 1,400 genes. These genes perform a variety of different roles in the body. (Note: So I believe your answer will be 46; 23x2)
What do the regulatory regions found in a chromosome primarily regulate?
The expression of genetic regions
What are regions of the chromosome with few functional genes called?
Regions of the chromosome with few functional genes are called gene deserts or gene-poor regions. These regions typically have a lower density of genes compared to other parts of the chromosome, and are often associated with non-coding DNA or regulatory elements.
Regions of DNA within each chromosome?
gene
What is heteropycnotic cromosome?
This is the characteristic of how much stain different regions of a chromosome take up..making some regions darker than others. This term can also refer to the X chromosome that has become a barr body in a female.
