What modification neutralizes the charges on histones and looses up the interactions between histones and DNA? - Answer- ACETYLATION Two types of post-transcriptional modifications that take place in the mRNA of eukaryotes - Answer- the addition of a CAP at the 5' end of the transcript and the addition of a POLY A sequence at the 3' end of the message Nucleic acid blotting is widely used in recombinant DNA technology. In a Southern blot one generally - Answer- Hybridizes filter-bound DNA w...

MBG 2040 / MBG2040 QUIZ 1 ANSWERS Question 1 0 / 1 point In pea plants round seeds are dominant over wrinkled. The gene responsible for this trait exhibits typical Mendelian expression and is designated with a D for the dominant allele and with a d for the recessive allele. If two heterozygote plants are crossed (Dd x Dd) this would be considered a _ . Homozygous Cross Dihybrid Cross Heterozygous Cross Question 2 0 / 1 point In reference to the pedigree above, what ...

Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but more closely resembles one homozygous phenotype than the other? - -incomplete dominance -Which mode of inheritance results in the phenotype of a heterozygote being indistinguishable from that of an organism homozygous for the dominant allele? - -complete dominance -Which mode of inheritance results in both alleles being detected equally in the heterozygous phenotype? - -codominance -A...

5. You are studying a mutation in mice, which acts dominantly. Mice that have only one copy of the allele carrying this mutation have a kinky tail phenotype You identify the gene that the mutation affects and find that the codon that encodes the second amino acid in the predicted protein has been mutated to a stop codon. Would you characterize this mutation as a loss-of- function or a gain- of-function and what specific subtype (hypermorphic, antimorphic, etc. ) within these categories? Exp...
