Davion is in the clinic for a check up. At birth, you diagnosed him with Treacher-Collins Syndrome, a genetic disorder that affects the development of the bones and other tissues in the face. TCS is believed to be caused by a change in the gene on Chromosome 5, which affects facial development. About 40% of the time, one parent has Treacher Collins Syndrome. If the parents of the affected child are not affected by the syndrome, the chances of a sibling having Treacher Collins are minimal. Which organelle in the cell is responsible for Davion's inheritance of this genetic disease?

Answers

Answer 1

According to the research, the correct answer is ribosomes. The organelle in the cell that is responsible for Davion's inheritance of this genetic disease called Treacher-Collins Syndrome is ribosome.

What is Treacher-Collins Syndrome?

It is a syndrome considered polyformative when multiple malformations are found, it has an abnormal craniofacial development pattern, and it is caused by a mutation of the chromosome that codes for the protein melasa.

In this sense, the protein melase is involved in ribosomal biogenesis, that is, it is involved in the transcription of the ribosomal DNA gene, as an important component of cell organelles called ribosomes, rRNA is essential for protein assembly.

Therefore, we can conclude that according to the research, Ribosome mutations of the protein melasa have been associated with Treacher Collins syndrome.

Long bones have a diaphysis, the middle part of the bone, which connects its two ends, known as the epiphyses. The medullary cavity is lined by the diaphysis, which is formed by compact bone. The epiphysis is composed mainly of spongy bone and is covered by a thin layer of compact bone.

How is a bone structured?

The bone structure is made up of several types of connective tissue (dense, bone, adipose, cartilaginous and blood), in addition to nervous tissue. It is the outermost, being a thin, fibrous membrane (dense connective tissue) that surrounds the bone, except at the articulating regions (epiphyses).

Prezygotic and Postzygotic barriers are reproductive isolation mechanisms, which avoid mating events or prevent viable and fertile mixtures between different species. Pre-zygotic barriers: One bird species prefers open areas, whereas another bird species prefers wooded areas. One frog species mates in the spring, whereas another frog species mates in the summer. Postzygotic barrier: A horse and donkey mate to produce a sterile mule. Individuals from two different species mate, but the resulting embryo dies before birth.

What is reproductive isolation?

This is a mechanism through which different species or populations do get to mate and produce fertile offspring. This mechanism allows the accumulation of genetic differences and favors speciation.
