The gene “C” codes for the membrane-associated protein C, responsible for signal transduction. A mutant allele of this gene, Cm, encodes a malfunctioning C protein, which has the same size as the wild type and associates with the plasma membrane like the wild type, but it has no function in signal. With respect to the expression of the C proteins, the wild-type allele is: A. codominant to the Cm allele. B. dominant to the Cm allele. C. haploinsufficient. D. incompletely dominant to the Cm allele.

Answer #1

Answer is B.

Explanation:

It is given that wild type allele encodes the signalling in the cell but the mutant allele don't encode any signalling in the cell. This suggests that the wild type allele (C) is dominant to the mutant allele (Cm).

    Help with both please! 10. In a wild-type diploid fungus, protein E (encoded by the haplosufficient gene “E”') normally homodimerizes, and the E-E dimer catalyzes a biochemical reaction necessary for the production of a dark pigment. E represents a mutant, dominant negative allele of gene E. What is the predicted phenotype of a fungus cell of genotype ET/E”, and why? A) mutant (no pigment production), as E is haplosufficient B) mutant (no pigment production), as no E-E dimers will form...

    In zebrafish, the half baked (hab) gene is caused by a mutation in E-cadherin. A new allele of this gene, k51, has a wild-type phenotype as a heterozygote, and a strong lethal phenotype as a homozygote. However, k51/deletion has a slightly more dramatic phenotype than k51/k51. This test tells us that the new allele is: O a null allele O codominant. O dominant lethal. O temperature sensitive. O haploinsufficient. O a leaky allele O incompletely dominant. O dominant negative. O...

    In a wild-type carnivorous plant, protein X is encoded by a haplosufficient gene “X”. The X protein normally homodimerizes. The X-X dimer enzymatically catalyzes a biochemical reaction that is critical for the digestion of insects that it traps. XD represents a dominant negative allele, a mutation, of gene X. What would be the predicted phenotype of a plant with the genotype X+/XD ? Which one of these pieces of information allows you to reach that conclusion? a. The plant would...

    ACTN3 is a gene that encodes for alpha-actinin-3, a protein expressed only in type-Il muscle fibers. The R allele has been associated with high endurance and speed in athletes. However, not all individuals that have the R allele show the "fast" phenotype. Lets pretend that the Rallele is dominant, and there is another gene involved in mitochondria efficiency, the A allele codes for highly efficient mitochondria and the a allele codes for low efficient mitochondria. When mitochondria efficiency is low,...

    Last guy got it wrong - Thank you. 2. You discover a signal transduction pathway that regulates actin polymerization. SigC is the ligand, which binds to and activates a receptor tyrosine kinase (RTK). Activation of the RTK leads to the activation of the Ras protein, which then activates the protein kinase PK1 that phosphorylates the RingA protein on S34. When SigC plasma membrane phosphorylated, RingA binds EXTRACELLULAR to the gene regulatory SPACE inactive Ras protein activated Ras protein protein, AP1....
