Inessa [10]

Answer:

The question lacks the illustrative diagram, the diagram has been attached as an image.

The correct answer, according to the picture is A.

Explanation:

All cells undergo division (mitosis or meiosis). Meiosis reduces the chromosomal number of the daughter cells by half. According to the question, The female species of Myrmecia pilosula ant has diploid cells total number of 2 chromosomes.

At the metaphase stage of meiosis I, homologous chromosomes (similar but non-identical chromosomes received from each parent) aligns at the center/equator of the cell called METAPHASE PLATE. This alignment is done when spindle fibres attach to the kinetochores of the chromosomes.

Option A in the diagram depicts this arrangement of homologous chromosomes in the centre of the cell. Note that, each chromosome has replicated to form SISTER chromatids held together at the centromere. These chromosomes will be pulled apart in the next stage (Anaphase).

Option B depicts only one replicated chromosome

Option D depicts separation of sister chromatids (only one chromosome)

Option E depicts separation of sister chromatids of two chromosomes which occurs in the Anaphase of meiosis II

Artyom0805 [142]

Answer:

DNA coiled to Histone protein.

Explanation:

1) DNA wrap itself around the histone protein due to the negative charge on the histone, that packed DNA tightly so that it can't be used in protein synthesis.

2) Prosthetic groups are itself co-factors that bind tightly to enzymes or proteins. they can be organic or metallic ions and attached to proteins by covalent bond.

3) The transfer of mitochondrial DNA (mtDNA) from mother to  her offspring is known as  maternal inheritance. only female can transmit  mtDNA beacuse, it can be transmitted through female eggs only. One can inherit mtDNA from exclusively their mother.

Since we now have the technology to use genetic fingerprinting to catch criminals, should we make every US resident provide a bl
rosijanka [135]

Answer:

It can be easily exploited by criminals, and it puts our undercover police officers and FBI officers in danger. Also, police officers are already swamped with work and criminal activity as is. It would also be ridiculously hard to get everybody already registered as a resident it the U.S. Take into account the different family types, and how hard it is for single mothers with children.

On the other hand, adding this, despite the obvious hardships, will make catching criminals much easier. Our blood DNA is unique to every human being. It would be extremely helpful to have a system like this in place. This would, at first, be hard to establish, but once it settles in, police officers would be able to spend much more time at home with their families instead of filling out paperwork for overtime.
