ANSC 1401 Crossland Exam 3 Questions and Answers Already Passed DNA is located in the chromosome of the nucleus of the cell. True Gene Small section of DNA that codes for a specific purpose. Genome Sum of genetic material of an animal. Trait Observable characteristics Allele you receive one of these from each parent which can make a gene have various forms of genotypes and phenotypes. Mitosis somatic cell division Meiosis Development of germ cells, aka gametogenesis C...

MEDICINAL CHEMISTRY AND MOLECULAR PHARMACOLOGY MCMP 442 Exam 2 2024 – QUESTIONS AND DETAILED CORRECT ANSWERS Which is the most likely reason that HIV-infected people with heterozygous HLA loci have a delayed progression to AIDS compared with patients who are homozygous at one or more HLA loci? A. The greater number of HLA alleles provides a wider variety of HLA molecules for presenting HIV-derived peptides to CD8 T cells even if HIV mutates during the course of infection. B. Heteroz...

The ecology of algae in aquatic ecosystems parallels that of plants in terrestrial ecosystems. Make three points to support this statement. - Aglae and mosses/plants have similar features such as: - branched apical growth - cuticles - asymmetrical flagellated cells - cellulose, thylakoids, chlorophyll b, some have 2 flagella... If some Euglenoids have the same pigment as green algae and higher plants, why are they not so closely related? - secondary endosymbiosis Why evolve towards a s...

What type of serological testing does the blood bank technologist perform when determining the blood group of a patient? A. Genotyping B. Phenotyping C. Both genotyping and phenotyping D. Polymerase chain reaction Answer B Phenotyping, or the physical expression of a genotype, is the type of testing routinely performed in the blood bank. An individual, for example, may have the AO genotype but phenotypes as group A. If anti-K reacts 3+ with a donor cell with a genotype KK and 2+ ...

Interpret this statement: Extinct fossil species are typically succeeded by similar living species - Answer Extinct and living forms represent ancestors and descendants Which is an example of developmental homology a) gene content b) similar organismal structures c)vestigial traits d) similar embryonic traits - Answer d) Which is not one of Darwin's 4 Postulates: a) Individuals in a population vary in their traits b) These differences are not heritable; they are not passed onto offs...

A new fossil of a mammal is discovered from Eocene deposits that is remarkable for its extremely short neck coupled with very long legs. What would you predict for the number of neck vertebrae that would be found in this fossil? - 7 Alleles are most likely to show linkage disequilibrium if they: - occur very close together on the same chromosome An approach to estimating the narrow-sense heritability of a trait - measure the trait in parents and their offspring for comparison Based on the...

What are the positives to sexual reproduction? 1. increased heterozygosity 2. purging of deliterious mutations 3. recombination and cross over 4. behavior What is asexual reproduction? offspring arise from a single organism, and inherit the genes of that parent obly; it does not involve the fusion of gametes and almost never changes the number of chromosomes - typically single cell organism - horizontal gene crossover What is sexual reproduction? the production of offspring by combining geneti...
