    DNA sequencing and coding

    See attached for full problem description You are given a genomic DNA from human with unknown function. You suspect this piece of DNA might code for a protein, but you are not sure which of the 6 frames are really coding. Which frame is most likely coding? Which is the most significant domain match? Does this prote

    Hidden Markov Model

    CpG islands are stretches of CG-rich sequences in the genome. They are often of functional important, as 50% of the human genes have a CpG island around 500bp upstream of the transcription site. Of course, CpG sequence is not only CG, and non-CpG island sequences could still contain some CG. Therefore, we could use HMM to predic

    What is the human RefSeq sequence otholog of NM_007527?

    Use reciprocal blast (bi-directional best hit) to find the human RefSeq sequence ortholog for mouse RefSeq sequence NM_007527. Note you should limit the database to RefSeq and select the right organism. You can obtain NM_007527 sequence by searching Nucleotide for NM_007527 from the the NCBI website.

    X-linked Inheritance & Autosomal inheritance

    In humans, red-green color blindness is recessive and X-linked, while albinism is recessive and autosomal. What types of children can be produced as the result of marriages between two homozygous parents, a normal-visioned albino woman and a color-blind, normally pigmented man?

    Determine the frequency of allele A

    50. Determine the frequency of allele A after one generation under the following conditions of migration: (a) P=0.6; Pm=0.1; m=0.2 (b) P=0.2; Pm=0.7; m=0.3 (c) P=0.1; Pm=0.2; m=0.1

    (1) Two inbred strains of mice, one strain with black fur and one strain with brown fur, were crossed. All of the offspring had black fur. If the offspring are bred together, what percentage of their offspring will have black fur? (2) Given the B and b alleles from the above question, and the T and t alleles which determine

Genes that are located at the same position on homologous chromosomes are called A) recessive B) dominant C) alleles D) albinism 5. Which of the following would represent the sex chromosomes of a normal female? A) XX

    Using Probability to solve a genetic problems

    Hi, I don't have a problem with the question itself but i don't understand how my textbook use probabilty in solving the problem. How many genetically different eggs could be formed by a women with the following genotypes? Aa bb CC DD Now it's obvious that one gamete will have (A b C D) and the other gamete will hav

    4 genetics questions

    1. Draw all possible chromosome configurations in Metaphase I with a dihybrid AaBb. 2. Do the same things as in question 1 for the genotype AaBbCc. 3. How many types of gametes would result from a dihybrid AaBb? What are they? 4. What portion of the zygotes will be a. AaBBCc? b. AABBCc? c. AaBbCc?


    For the problems attached please show the symbols used in human pedigree analysis and/or Punnett Square if needed. Please also explain answers. Thank you! --- 1.
