In next week’s lab you will be determining your genotype for PV92, a human-specific Alu insertion on chromosome 16. PV92 only has two alleles: the presence (+) of the Alu insertion, or the absence (-). This means that you will have one of three PV92 genotypes (++,+-,or --).
1. Evolution: Genetic Evidence – Transposons. During or after you watch the video, answer the following questions:
What is a transposon?

What is a SINE? short interspers transposable elements that are usless to the gemome but can be used to be compares to other sequences of other individuals.

What is a LINE? long interspers transposable elements that are usless to the genome...

Where do you get your LINES and SINES?
They are inherited from your parants.

How did biologists use transposons to examine the evolutionary relationship between whales and hippos? …show more content…
2. Read the Article: “Functions and Utility of Alu Jumping Genes”. As you read, answer the following questions (they go paragraph by paragraph and will help you understand the reading).
Introductory paragraph:
In your own words, define an Alu element? Alu elements are DNA sequences that are phenotypically usless bye genotypically significant. They can replicate with the help of various enzymes and incerts themselfs into new locations of the genome.
What types of organisms have Alu elements? only primates

Short Interspersed Elements (SINEs): The Alu Example
Describe how a retrotransposon is replicated. It is transcribed into mRNA by RNA polymerase and then converted into a DNA molecule by reverse transcriptase.
What does it mean to be
