Explain. no, it wouldnt have the DNA OP 10. The S phase stands for synthesis, which means to make or build something more complex out of simpler parts. Scientists know that during the S phase DNA is being made in the nucleus of the cell. Why do you think the cell needs to make more DNA at this time in the cell cycle? 11. Refer to Model 1. The chromosomes that are shaped like "X" (made of two sister chromatids) have double the amount of DNA than the chromosomes that are shaped like "I."

- Genetics in Practice case studies are critical-thinking exercises that allow you to apply your new knowledge of human genetics to real-life problems. Case study Michelle was a 42-year-old woman who had declined counselling and amniocentesis at 16 weeks of pregnancy but was referred for genetic counseling after an abnormal ultrasound at 20 weeks of gestation. After the ultrasound, a number of findings suggested a possible chromosome abnormality in the fetus. The ultrasound showed swelling under the skin at the back of the fetuss neck; shortness of the femur, humerus, and ear length; and underdevelopment of the middle section of the fifth finger. Michelles physician performed an amniocentesis and referred her to the genetics program. Michelle and her husband did not want genetic counseling before receiving the results of the cytogenetic analysis. This was Michelles third pregnancy; she and her husband, Mike, had a 6-year-old daughter and a 3-year-old son. At their next session, the counselor informed the couple that the results revealed trisomy 21, explored their understanding of Down syndrome, and elicited their experiences with people with disabilities. She also reviewed the clinical concerns revealed by the ultrasound and associated anomalies (mild to severe intellectual disability, cardiac defects, and kidney problems). The options available to the couple were outlined. They were provided with a booklet written for parents making choices after the prenatal diagnosis of Down syndrome. After a week of careful deliberation with their family, friends, and clergy, they elected to terminate the pregnancy. Do you think that this couple had the right to terminate the pregnancy in light of the prenatal diagnosis? If not, under what circumstance would a couple have this right? What other options were available to the couple?Hi im having some trouble with this question, if someone could help solve these with an explanation it would be very helpful! In cats, a gene on the X chromosome (X-linked) makes the protein amelogenin, which helps direct the formation of tooth enamel. A mutation in an amelogenin allele changes the amino acid sequence of the protein and can cause a condition called amelogenesis imperfecta, leading to defects in a cat’s tooth enamel. In one type of amelogenesis imperfecta in cats, the allele associated with the condition, a, acts in a recessive manner. Its dominant counterpart, A, results in normal levels of amelogenin. Additionally, the dominant allele H at an autosomal locus that regulates the expression of the protein Sonic Hedgehog is responsible for polydactyly (the presence of extra digits on each foot, “double paws”) and the expression of its recessive counterpart h results in the absence of polydactyly (having the 5 digits per front paw, and 4 digits per hind paw). A female cat…Genetic variation in organism is due to?
- Genetics (Study of genes) O a. All the other choices are valid O b. Our traits can be controlled by one or more genes O c. It is the study of the mode of transmission of genes from one generation to the next. O d. There are in general two copies of each gene called alleles in every diploid cell, with one allele on each homologous chromosome.
