to only 23 rounds for a woman of age 20. That is a 6.5-fold greater number of cell divisions and proportionately greater opportunity for new point mutations. Yet, on average, 20-year-old men contribute only about twice as many new point mutations to their offspring as do women. How can you explain this discrepancy?

to a maximum of 23 rounds for a lady of 20 years. This corresponds to a 6.5-fold increase in cell divisions and a proportionately increased possibility for new point mutations. Despite this, 20-year-old males produce around twice as many new point mutations to their progeny than women do. How do you account for this discrepancy?
traffic deaths in 10 years. Does daylight savings time increase the number of traffic deaths? (Many countries are in the process of getting rid of the time change - even though the Senate did vote to stop the time change the legislation seems to have stalled (as usual!)). 6) Epistasis is a phenomenon in which one gene controls the expression of another. In one case, a dihybrid cross should yield a 9:3:4 ratio. You collect the following data on mice: black coat: 218 Is there any reason to doubt the ratio of 9 black: 3 brown : 4 white? brown coat: 76 white coat: 89
Gene Expression and the Impact of a Mutation. Can someone help me to answer the question 8 and 9, please? 8. How has the mutation altered the polypeptide? Is the function of the hemoglobin molecule (which includes 2 ẞ-globin polypeptides and 2 a-globin polypeptides) impaired? (Read your book to learn more about sickle cell disease.) 9. What is the relationship between the genotype in this case and the individual's phenotype? asap please
Part A. When a mutation arises, it can have three possible consequences for the individual: beneficial, selectively neutral, or detrimental. Order these from most likely to least likely. Part B: The spread of a mutation in subsequent generations will depend on its effect on individuals that inherit it. Re-order the three possibilities in part A to indicate which is most likely to spread and become overrepresented in subsequent generations, and which is most likely to become underrepresented or disappear from the population.
Research cancer mutation. Provide the link to the research article that gives you your information. One good resource to use is PubMed. Then answer the following questions, in 3 paragraphs, 3-5 sentences each. 1. What kind of disease/cancer does this mutation cause? 2.What happens during transcription to cause this mutation? 3. Is this trait passed on to progeny? Can the progeny be a carrier or simply affected?
8 points total. Within the general field of biotechnology, DNA technology uses modern laboratory techniques for the studying and manipulation of genetic material. Explain how DNA might be sequenced, analyzed, and "cut and pasted" as DNA technology is employed. In addition, outline one way in which DNA technology could be employed to improve human lives. I 3
You have two patients. Both patients have very low levels of P53 protein. Patient #1 also has very low levels of MDM2 protein; patient #2 has very high levels of MDM2. For each patient briefly describe (briefly justify your answers); Which of the two genes are mutated?P53 or MDM2? Is this an oncogenic or tumor suppressor mutation? Would treatment of the patient with Nutlins be appropriate?
True or false? The most common form of Down's Syndrome results from a spontaneous, somatic, gene mutation.

With Taq polymerase replacing magnesium with manganese case a higher mutation rate. True False
Question. Rewrite the following sentences after correction. (Subject: Biotechnology) The variation in the length of tandem repeat of microsatellite DNA has serious translational affects as this is due to its coding region. Correct: If one parent has sickle cell anemia and other has carrier genotype than there is 25 % chance that any offspring is carrier. Correct: Sickled WBC block the flow of blood and Calcium as they stick together and caused by frame shift mutation. Correct: The N1303K mutation in the CFTR gene of CF patients is autosomal dominant disorder due to insertion of asparagine at 1303. Correct: If a person RBCs have B surface antigen and it will clump with antigen B such clumping indicates Blood type B. Correct: Indirect ELISA can detect polygenic gene expression. Correct:
Correct answers already provided! Please don't just tell me the answers bc I know them already. Help me with my own question. I get everything else in this problem other than the third option: Introduce the mutant human HD allele as a transgene into the mouse genome with transgene integration anywhere in the mouse genome. Why is the first question (left) okay with introducing mutant human HD allele and the second question (right) is not? I heard that introducing allele without using CRISPR-Cas9 is very rare and difficult. If so, how does it work in the first problem (Hungtinton's chorea)?
