It should be D. The blood pressure would increase!
Answer:
Monozygotic twins
Explanation:
Monozygotic or identical twins are those that originate from a single ovary_ and a single sperm and therefore share the same genetic load.
What happens in these cases is that the embryo splits in two, and depending on the moment in which this happens, different configurations can be expected in the development of the placenta.
When the embryo is cleaved within the first four days after fertilization it results in a bicorial-biamnotic pregnancy, that means, two sacs and two independent chorions will be visible (exactly the same as in the case of dizygotic twins from two different embryos).
Two atria and two ventricles..
The new cells would have incorrect number of chromesomes
Answer:
DNA packaging is the method to convert long DNA into condensed chromosomes. Histone protein is responsible for basic level packaging of DNA into the nucleosome. Histone proteins are positive in nature that neutralize the DNA's negative charge.
A nucleosome consists of eight histone proteins which wraps around 147 bp of DNA. Each nucleosome has linker histone which forms chromatosome.
The next level of organization is the compaction of nucleosome into approx 30nm diameter fiber due to the attraction between nucleosomes.
Then protein condensin helps in making the 30 nm chromatin fiber to condense more to become a chromosome which is 1000 fold smaller than its original length.
