Textbook Question
Chapter 15, Problem 1CC
Using the figure below, describe the stages that may have led to the origin of life.
Expert Solution & Answer

Summary Introduction
To describe: The stages that lead to the origin of life.
Introduction:
The life on earth is evolved from the primitive life forms. According to scientists, there are many theories and experiments which prove the origin of life on earth. The origin may be from biomolecules, DNA or RNA as a genetic material is also considered as the point from where the life begins.
Explanation of Solution
The stages that show the origin of life are as follow:
- The monomers formed by abiotic synthesis are collected in the atmosphere. The collection of molecules may be through the influence of lightening and UV radiations.
- The reason of the formation of monomers is the heat from hot rocks and volcanic activity. Now, the short RNA polymers are formed from the combination of monomers.
- The membrane surrounds the polymers and differentiates between the external and internal environment.
- The replication of RNA polymers takes place through natural selection, in this step. The polymers are influenced and pass to the new protocells

- Molecular 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. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank youarrow_forwardMolecular Biology Question Please help.
