Q1. Each allele of single gene in a diploid cell during the G1 phase is present as part of a single (double-stranded) molecule. The Drosophila genome is approximately 150 Mb. which means that single haploid genome (one allele of each gene) would be 150,000,000 base pairs. Recalling that Avogadro's number is 6 x 10^23 (no units; this is a "pure" number), how several diploid Drosophila cells would be needed to have 1 picomole of each allele?
Q2. In peaches, Fuzzy skin (F) is completely dominant to smooth (nectarine) skin (F), and hetrozygous condition of oval galnds at the base of leaves (G ^o) and no glands (G^N) gives round glands. A homozygous fuzzy,no-gland peach variety is bred to a smooth, oval-gland variety.
a) What will be appearance of the F1 peaches?
b) What will be appearance of the F2 peaches?
C) What will be appearance of the offspring of a cross of the F1 peaches back to that smooth,oval glanded parent?
What type of compensation plan will you recommend? What are some of the problems you want to be aware of. Develop new coating methods and new applications of coating.
List whether the movement is diffusion, osmosis, active transport, or bulk flow. Clarify the adaptations that increase the effectiveness of this movement. what is the meaning of this observation.
Diploid nuclei of the ascomycete, Neurospora crassa, contain 14 chromosomes. A single diploid cell in an ascus will undergo one round of meiosis, followed in each of daughter cells by one round of mitosis, producing a total of eight ascospores.
Approximation the age group and gender (where possible) of the individuals in this find. Throughout exposure to elevated glucose, a yeast cell's membrane glucose transporters will rapidly enhance so the cell can import glucose. Which will represent t..
Which condition is best described while the ovaries shut down their production of eggs and hormones like estrogens and progesterone approximately 30 years after they started.
Male frogs give calls that attract female frogs to approach and mate. Researchers examined mating calls of closely related tree frogs in South America. What outcomes be able to occur where the ranges of two species overlap.
Why are algae important in nature. Joan and Alex Smith have five daughters who are quite dissimilar in appearance and talents. Examine why this occurs based on the 2 events in meiosis that enhance genetic diversity.
Oceans receive materials from land primarily as runoff from rivers. Which of the statements is true regarding the materials and nutrients found in the oceans? Most elements that enter the oceans from other compartments remain suspended in the water.
How do these duplications arise and what do they propose in terms of mechanisms of transposition. Could you help to understand FEV1/FVC and how the expected percentage of this figure relates to respiratory problems.
If you were asked to create a karyotype from the chromosome spreads you made from HeLa cells in Activity 4.2.1, list materials you would use and explain how you would make the karyotype.
