Your answer: The precipitin line occurs when the antigen and antibody are in optimal proportions and cross-linking occurs forming an insoluble precipitate. 3. Did you think human serum albumin and bovine serum albumin would have epitopes in common? How well did the results compare with your prediction? Your answer: yes;results showed they have partial identity Activity 3: Indirect Enzyme-Linked Immunosorbent Assay (ELISA) Lab Report 1.
To confirm this idea, Marshall Nirenberg used a synthetic RNA containing only one kind of base. What question was his experiment attempting to answer? 8. Briefly describe Seymour Benzer’s experiment that answered the question: “Do mutations in the DNA sequence of a gene correlate with protein changes?” 9. Marshall Nirenberg and Heinrich Matthaei used mRNA made up of repeating uracil nucleotides in a cell free extract.
Answer: C Topic: Concept 14.1 Skill: Knowledge 3) Which of the following statements about Mendel's breeding experiments is correct? A) None of the parental (P) plants were true-breeding. B) All of the F2 progeny showed a phenotype that was intermediate between the two parental (P) phenotypes. C) Half of the F1 progeny had the same phenotype as one of the parental (P) plants, and the other half had the same phenotype as the other parent. D) All of the F1 progeny resembled one of the parental (P) plants, but only some of the F2 progeny did.
CMT1A is an autosomal dominant disease. An autosomal dominant disease means that only one copy of the abnormal gene is needed in order to have the disease. (2) CMT1A is caused by genomic duplication on chromosome 17, see figure 3. The Duplication is

Marker: a gene or DNA sequence with a known location that can be used to localize a gene of interest with an unknown location. ANSWERS TO APPLIED QUESTIONS 1. a. D b. C. c. A d. H e. G f. C g. H h. F i. G 2. Haplotypes can reveal if people without symptoms have the haplotype associated with the condition. These people are non-penetrant.
But since the ratio of dominant to recessive alleles are not the same, we can use the allele frequencies for both alleles for a more accurate prediction. The first part of this lab consists of a taste test to determine the allele and genotype frequencies within a class population. The three samples will be based on the bitter taste receptor gene. If there is a strong bitter taste present, the result will
These traits are carried on alleles, and we are given one by each parent. If both alleles have the same trait, then you are homozygous for the gene. If there are two different alleles, then you are heterozygous for the gene. A particular gene can be dominate, which means it will express. However we often share hidden traits as well, called recessive traits.
http://www.genome.gov/25020028 This site discusses the history behind cloning, when cloning receive its scientific breakthrough, the advantages and disadvantages of cloning, and how technology plays a part in cloning. I would use this information in my paper in regards to comparing advantages and disadvantages of cloning, and also go in to the ethical reasons why or why not to clone. 4. http://www.ama-assn.org/ama/pub/physician-resources/medical-science/genetics-molecular-medicine/related-policy-topics/stem-cell-research/human-cloning.page? This site gives valuable information on the statistical data of clones. It goes in depth of how many times mammal clones were attempted to be created, and how many times they actually succeed.
Nurture refers to traits that are taught or that one may have gained through experience after conception. The debate lies in deciphering whether the trait came from the nature or the nurturing aspect, or often times both. We know that genetics do have some specific roles such as a persons’ look or certain genetic disabilities that come straight from gene mutation or are passed on, but in the debate of nature vs nurture it is of those traits that are behavioral. There are two major sides to the nature vs nurture debate. Those who see personality traits as strictly hereditary and those who believe traits are learned from birth on, through experiences (McLeod, S.A. 2007).
