Answer:
the reporter gene can randomly insert near to an enhancer sequence which can induce its expression
Explanation
Enhancers are genetic sequences capable of activating gene expression by binding to specific proteins (e.g., transcription factors). Enhancers can regulate the expression of nearby genes located thousands of nucleotides away, i.e., over several kilobases away. In the human genome, it is well known that enhancers are scattered across the 98% of the genome. In this case, it is expected that the reporter GFP gene construct is randomly inserted near an enhancer sequence (a 10% chance of insertion), thereby being regulated by that enhancer.
Answer:
D. Aa
Explanation:
Given:
Jill (mother) is heterozygous for gene A --------- i.e Jill = Aa
Jack (father) who is homozygous recessive for gene A-------- i.e Jack = aa
Now if both cross and fertilization occurs, we have:
A a
a Aa aa
a Aa aa
The offsprings are (Aa, Aa, aa, aa)
Nondsijunction is the inability of homologous chromosomes to seperate properly during cell division. Now, we were told that this fertilization undergone nondisjunction in meiosis 1. Hence, both homologous chromosome move into the same daughter cells instead of different daughter cells because separation of homologous chromosome does not occur properly.
Therefore the result of these fertilization of a normal haploid sperm with an egg that had undergone nondisjunction in meiosis yields offspring with genotype Aa of their Mother (Jill).
I guess the point about increasing level of oxygen is most correct......
Answer:
Maternal inheritance means the transfer of characters from mothers to offspring through mitochondria. The paternal leakage means some mitochondria transfer from the father as well.
As the information given in the question, the amount of DNA from father's mitochondria is small. The quite small amount of DNA will not affect the conclusions and results that are made by the studies and do not affect the inheritance of mitochondrial DNA.
