Question
Chapter 10, Problem 31ESP
Summary Introduction
To determine: The model of DNA which consistent with the given observations.
Introduction: The analysis of the genetic material of primitive eukaryotes provides some important information. X-ray diffraction experiments show that the DNA of the organism have different dimensions and irregularities. A major hyperchromic shift is also observed on heating and analyzing at 260 nm (UV absorption).

Thank youarrow_forwardMolecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB.
