They carry 50%of genetic information
It is due to agitation of the heart. This is the result of a blow in the area directly over the heart.
Answer:
it is located 1000 nucleotides upstream of the gene’s core promoter - true
it is located 1000 nucleotides downstream of the gene’s core promoter- true
it is in the gene’s coding region - False
Explanation:
These enhancers are located 50 or more kilobases from the promoter they controlled upstream from a promoter, downstream from a promoter within an intron, or even downstream from the <u>final exon</u> of a gene which can be thousands of bp away from the gene's core promoter and can also occur thousands of nucleotides away from the gene's core promoter needing the activity of a DNA -bending protein that binds to the enhancer changing the shape of the DNA and allow interactions between the activators and transcription factors.
The researchers will use mice instead of opossums or humans to determine whether the cells of the ear bones originated from the same embryonic cells as the cells that form the jaw in other vertebrates because in this type of experiment, organisms that are ideal are the ones that have a short life span, easy to be researched on and easy to mantain.
It will be very tedious and demanding to use opossums and humans in this type of practical experiment because,it is against the culture and norms guilding human living and existence to use humans as model organisms,opossums as well are very bad model organisms because unlike the mice,opossums are long lived and it will be very difficult to raise and maintain an opossum in a laboratory.
Humans and mice are both mammals just that human is a higher mammal but they share similar features in terms of pattern of development,though there is a clear difference during their early development,so because of the common ancestry shared by the mice and humans,the result of the experiment on the mice with share a close similarity with the pattern that is expected in humans.
