Homework Answers
frameshift mutations are mutations that changes the reading frame from that point.
horizontal gene transfer is the transfer of genes between two organisms,organisms can be in different species.
intragenomic recombination is the recombination between the chromosomes within a cell`s genome.
so the mechanisms by which genes are transferred to the eukaryotic host from the bacteria is horizontal gene transfer.
so the answer is a) horizontal gene transfer.

Question 23 2.5 pts In 2015 Bibiana Montoya and Roxana Torres published a paper in Behavioral Ecology showing that brown booby birds, a tropical long-lived seabird, have gulars (throats) that vary in the intensity of green. They showed that male brown boobies with more intense green gulars produced healthier offspring and provided more parental care. Which TWO types of intersexual selection are brown booby birds...

Explain the proposed importance of “junk DNA” in the human genome with respect to the proliferation and horizonal transfer of cis-regulatory elements into new chromosomal locations. Explain, in as much detail as you can, how the mobile DNA, containing, these cis-elements, can influence expression of functional and genes and potentially enable new gene function or activity.

ΦC31 is a type of bacteriophage that infects Streptomyces bacteria. One gene in the bacteriophage genome specifies a recombinase called ΦC31 integrase that works through a mechanism slightly different from that of the recombinase shown in Fig. 6.30. Most importantly, the two target DNA sequences are different from each other. One called attP is 39 base pairs and is found on the circular bacteriophage chromosome, while the other—attB—is 34 base pairs long and is located on the much larger circular...
