The description of mutation, which would affect nucleotides, outside the coding region of a gene (beta-globin gene). Introduction: Mutations are permanent and heritable changes of the genome. They can result in diseases by altering the protein sequences. An altered protein sequence either folds incorrectly or does not fold at all. This consequence can render a protein dysfunctional and can cause diseases in the organism.

Question

1. a)What would happen if the aminoacyl tRNA synthetase responsible for charging alanine tRNAs also charged methionine tRNAs with alanine? b)What would happen if an individual was homozygous for mutant alleles of the gene encoding the aminoacyl tRNA synthetase responsible for charging leucine tRNAs?

In Figure 12-4, certain mutations decrease the relativetranscription rate of the β-globin gene. Where are thesemutations located, and how do they exert their effects ontranscription?

As part of a project investigating potential new drug targets in the fight against malaria, you are seeking to clone the gene for a protein from the malaria parasite Plasmodium falciparum. You wish to express this protein in BL21 (DE3) cells, a standard laboratory strain of Escherichia coli. After purification of your protein, you run an SDS-PAGE gel and notice that the major band has lower molecular weight than expected, so you fear you are getting a truncated version. 1. What technique could you use to confirm that you are obtaining a shortened version of your intended protein? explain
