How transposons could have led to selective advantages in organisms. Introduction: Transposons are genetic sequences that can more across the genome. That is why they are also called jumping genes. This leads to the change of nucleotide sequences that could result in mutation by translocation, insertion and deletions. This is why transposons hold a significant place in evolution of organisms.

Transposons are genetic sequences that can more across the genome. That is why they are also called jumping genes. This leads to the change of nucleotide sequences that could result in mutation by translocation, insertion and deletions. This is why transposons hold a significant place in evolution of organisms.

Expert Solution & Answer

Explanation of Solution

The movement of transposons led to the change in the ORF (open reading frame). This could hinder the protein synthesis, thus acting as a regulator. At times it is possible this happened in an important gene and the organisms were affected adversely. On the other hand it is possible that a harmful gene was silenced.

For example: If a transposon got incorporated into the gene that codes for the colour of an insect with a red coat then the organisms will no longer be red. It is possible that the predators will not be able to find its prey as it no longer is coloured. As this insect survives, it will reproduce and spread its genes (natural selection). Thus, in this case transposons led to selective advantage in a species.

The numerous repeat sequences found in organisms are thought to have been the work of transposons. The corn kernel colour change is also attributed to the jumping genes.

Conclusion

Transposons change the nucleotide sequences at random. There are chances that these changes could lead to advantages in species and cause evolution.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours. (Example: If percent is 20%, then Time in Hours = .2 * 24 = 4.8) Record your data in Data…
