Summary Introduction

Introduction: “Gene duplication” is the phenomenon of the occurrence of more than one copy of the genes in the genome of the organisms like the alpha and the beta globin gene family. It takes place in the genome due to the presence of the transposable genes inserted in the chromosomes. This causes the development of the formation of the unequal crossing of the chromosomes.

Sickle cell anemia is a widespread disease in many African countries and can be caused by a change in the amino acid sequence from glutamic acid to valine. A patient is diagnosed with the disease and a genetic fingerprint reveals the following DNA sequence for the gene: (a) (b) (c) (d) (e) Write down the mRNA sequence for the given DNA sense strand indicating the polarity. Derive the polypeptide from the mRNA molecule using the table of the genetic code (Table Q1 below) again indicating the polarity of the peptide chain. Indicate the position in the DNA molecule that could have caused the disease and write down all possible point mutations in the DNA sequence that could have caused it. [ The polypeptide chain is polymerized at the ribosomes using t-RNA molecules. Write down all possible t-RNA molecules with their anti-codons that are used to polymerize the amino acid VAL. Indicate the polarity. 3'-TAC TGA GCA AGA TTA CAT ACT-5' Explain what is meant by redundancy of the genetic code.…
If the codon AAA is mutated to AAG, it still codes for the amino acid, lysine, and the protein remains functionally the same; which of the following would best describe the result of this mutation? 1) frameshift mutation. O 2) insertion mutation. O 3) silent mutation. 4) nonsense mutation. O 5) back mutation.
If you were to hybridize a eukaryotic gene to its corresponding mRNA, the two molecules would not perfectly align. Why would it not? A) Exons contained in the gene have been removed from the mRNA via splicing.B) RNA polymerase adds introns to the mRNAC) Introns contained in the gene have been removed from the mRNA via splicing.D) RNA polymerase adds exons to the mRNA
