b. What percent of females would be expected to express haemophilia?

c. What proportion of the females would you expect to be carriers for haemophilia?

d. The observed frequency of women affected with haemophilia is actually higher than expected. Propose a genetic explanation for this.

All primary oocytes that a female mammal will ever produce are present in the ovaries at her birth. In humans, these oocytes mature at a rate of approximately one per month from puberty to menopause. What kinds of reproductive problems may result from the long retention of oocytes in the ovaries? Do you think that problems of this kind increased in incidence as women are choosing to delay childbirth?

If you do not wear contacts but you use or make cleaning solutions for your housework, how would you accurately prepare solutions to clean?

Along the loop of Henle, how does the movement of water and salt influence the volume and concentration of the filtrate.

inny Genestudy performs the following experiment. She wants to replicate a test strand of DNA using wildtype of Saccharomyces cerevisiae (budding yeast) and two mutants which she calls poor-rep1 and poor-rep2. She performs the experiment with her wildtype strain, and her test DNA strand replicates perfectly. She does the same experiment with poor rep-1 and discovers that this strain can only synthesize the DNA strand if she adds a purified wildtype DNA polymerase-a exogenously. When she performs the experiment with poor rep-2 she discovers that adding wildtype DNA polymerase-a has no effect. Which of the following scenarios is a possibility for the poor rep-1 and poor rep-2 strains.

The poor rep-1 strain has a mutation in the gene that codes for either PriS or PriL but not the gene encoding polymerase-a, whereas the poor rep-2 strain has a mutation in the gene that codes for polymerase-a.

The poor rep-1 strain has a mutation in the gene that codes for PriS and polymerase-a, but not PriL, and the poor rep-2 strain has a mutation in the gene that codes for PriS or PriL but not the gene that codes polymerase-a

The poor rep-1 strain has a mutation in the gene that codes for PriL and polymerase-a, but not PriS, and the poor rep-2 strain has a mutation in the gene that codes for polymerase-a, but not PriS or PriL

The poor rep-1 strain has a mutation in the gene that codes for Pola, but not for either PriS or PriL, and the poor rep-2 strain has a mutation in the gene that codes for either PriS or PriL but not for the gene that codes for polymerase-a .

All of the above are correct

P.S the answer in Q and A is wrong, so posting here thanks

Ralph Researcher studies transcription of his favorite gene, FAVE1, in bacteria. He notes that the wildtype strain of bacteria constantly expresses Favorite-1 Protein unless he the protein Squash-1 is also expressed. When Squash-1 is expressed, the level of Favorite-1 protein decreases. One of his mutant strains continues to express Favorite-1 Protein regardless of whether Squash-1 is present or not. What might be the regulatory mechanism of the gene coding for Favorite-1 and what is the role of Squash-1.

P.S. the answer in Q and A is wrong so i'm posting it here.

Suppose there is a gene called VID that codes for the incredible ability to play any video game. This gene is 360 nucleotides long, with no introns. The wildtype version codes for a protein consisting of 120 amino acids. Some people cannot play video games well at all. Their VID gene was isolated and sequenced and found to have a nonsense mutation. The resulting non-functional VID protein consisted of just 20 amino acids. However, some rare individuals who also carry this same nonsense mutation in their gene do have a functional VID protein consisting of the full 120 wildtype amino acids. Which of the following most likely accounts for these rare individuals with a mutation in their gene but a fully functional protein.

Imagine that you are driving a car through the Riverside neighborhood, and you see a basketball bounce across the road. Beginning with the transmission of the receptor potential, identify the areas of the brain that would be involved in the neurological response to the stimulus. What parts of the brain does the signal activate, how does it get there, what happens there as a result of the signal, and what is the output?

Histone proteins are among the most highly conserved proteins in eukaryotes. Histone h4 proteins from a pea and a cow, for example, differ in only 2 of 102 amino acids. Comparison of the gene sequences shows many more differences, but only two change the amino acid sequence. These observations indicate that mutations that change amino acids must have been selected against during evolution. Why do you suppose that amino- acid-altering mutations in histone genes are deleterious (harmful)?
