To determine: The ploidy of individuals with Down syndrome.
Introduction: Down syndrome is a genetic disorder and is regarded as a birth defect. It is mainly caused because of the presence of an extra copy of chromosome 21. Symptoms such as mild intellectual disability and physical growth delays are associated with Down’s syndrome. Developmental disorders are also seen in individuals with Down’s syndrome.
To explain: The reason due to which a modified chromosome causes Down syndrome in children.
Introduction: Birth defect refers to a significant abnormality which is present at the birth of an individual. Down syndrome is one of the examples of genetic birth defect. Down syndrome is caused due to an accident during cell division. Down syndrome is a genetic disorder and it is mainly caused due to the presence of an extra copy of chromosome 21.

- . Early in development, most human cells turn off expression of an essential component of telomerase, the enzyme responsible for addition of telomere repeat sequences (5’-TTAGGG) to the ends of chromosomes. Thus, as our cells proliferate their telomeres get shorter and shorter, but are normally not lost over the course of a lifetime. If cells are removed from the body and grown in culture, however they ultimately enter a state of replicative senescence and stop dividing when their telomeres get too short. By contrast, most human tumor cells express active telomerase, allowing them to maintain their telomeres and grow beyond the normal limit imposed by senescence - good for them, bad for us. Anticipating a universal cure for cancer, you set up a company to screen chemical ‘libraries’ for telomerase inhibitors. The company share price takes a dive, however, when a rival group generates a strain of telomerase-knockout mice. These mice breed happily for several generations, but…arrow_forwardResearch cancer mutation. Provide the link to the research article that gives you your information.

- Part I. Structure-Function Relationships in Genes 1. Consider the "two-line model" of a gene shown below - each line represents one strand of a DNA double helix, and the transcription start site is indicated as +1. Use the two-line models provided when answering the following questions. 3' 5' +1 Assume that you know RNA polymerase will move to the right during transcription. On the diagram above, do the following: • Label "upstream" and "downstream" on this gene • Label where you would find the promoter min I • Draw a box where you would expect to find the TATA box • Draw a third line below the model representing the RNA transcript (label the ends!) • Label one of the DNA strands as the template strand 3' 2. Now, let's try that again! This time assume that you know RNA polymerase will move to the left during transcription. Repeat the same tasks as before on the diagram below: 5' 5' 3' +1 I I 5' 3'arrow_forwardGene Interaction and Epistasis Hair color is due to the presence of melanin. There are two types of melanin produced by melanocytes. One is eumelanin, which is responsible for black (homozygous), brown (heterozygous), and blond (recessive) hair colors. The other is pheomelanin, which is responsible for red hair color. During melanin synthesis, MCR1gene converts pheomelanin to eumelanin. However, a variant of the MCR1 gene (MCR1variant), prevents this conversion. A cross between a blond-haired mother and a red-haired father produced 100% brown-haired children. When they came of age, one child married a double heterozygote, and both were blessed with 7 children; 2 with black hair, 2 with brown hair, 1 with blond hair, and 2 with red hair.
