Answer:
1) Describe the whole experiment shown in this document
Explanation:
The blue-white screen refers to a procedure of screening that allows for the brisk and convenient determination of recombinant bacteria in vector-based molecular cloning experiments. In the process, the DNA of interest is ligated into a vector. The blue colonies constitute of self-relegated plasmids that are devoid of DNA inserts obstructing the lac Z gene.
The white colonies contain bacteria that conduct plasmids, which possess the inserts of DNA fragments that obstruct the lac Z gene. Therefore, the researcher needs to sequence the plasmids of the white colonies prior to knowing which allele it constitutes.
Answer:
<h3>A) Only Male offspring can inherit the disease.
</h3>
Explanation:
As per the pedigree chart, only the males are shown as affected by the disease. Thus, it must be a sex-chromosomal inheritance, expressed in the Y chromosome or the male chromosome.
As the females in the family are unaffected, hence the mother in the original parental generation cannot be a carrier.
It is likely that the father from the original parental generation might be the carrier.
As there are affected individuals in both the generation after the original parental generation ( the last generation having two more affected males), the statement that the chances of inheriting the decease with each successive generation is not true.
Answer:
It shows their evolutionary history and their possible common ancestor.
Explanation:
Similarity of early embryos of different species is a phenomenon observed by many scientist such as Karl von Baer, Charles Darwin and Ernst Haeckel.
Karl von Baer even formulated the law of embryonic development. He explained that there is a certain embryonic form, basic form, which is similar in different species. After this stage (basic form) each species develops independent-there is a branching pattern of further development.
So, according to von Baer development goes " from the most general forms the less general".
