How are the modes for reproduction different in unicellular and multicellular organism.
Neporo4naja [7]

The unicellular and multicellular organism are different in asexual and sexual mode of reproduction.

The reproduction is the phenomenon which involves the production of an offspring by particular individuals or individuals to propagate there species. Reproduction are of two types:

1. Asexual reproduction: In asexual reproduction, they does not involve the fusion of gametes. The unicellular organism reproduce mainly by binary fission. In this, a single cell divides into two daughter cell. The daughter cell completely resembles their parent. It involves only one parent.

2. Sexual reproduction: In sexual reproduction, there is a fusion of gametes that brings changes in genetic combination. The germ cell undergoes meiosis that produces haploid gametes that fuse to form new individuals. It involves either one or two parents.

dynamic modeling of alpha-synuclein aggregation for the sporadic and genetic forms of parkinson's disease
Triss [41]

Numerous degenerative neurological conditions, most notably Parkinson's disease, have been linked to an excessive buildup of alpha synuclein (a-syn) in the brain. Intraneuronal inclusions, often known as Lewy bodies, are neuropathological characteristics seen in Parkinson's disease, Lewy body dementia, and other synucleopathies. The aggregation of a-syn is their main structural component. A-syn accumulation, aggregation, and ensuing Lewy body formation can be attributed to a variety of biological processes. These include genetic changes in parkin, synuclein, or the deubiquitinating enzyme ubiquitin C-terminal hydrolase (UCH-L1), which results in less efficient removal of a-syn via the ubiquitin proteasomal pathway (UPP). Additionally, environmental variables and an age-related decline in antioxidant defense mechanisms that heighten oxidative stress and can have an impact on the formation or clearance of a-syn are intracellular insults.

We focused on changes in the aggregation and clearance of a-syn as impacted by the UPP and the oxidative stress pathways in our dynamic models of a-syn processing in both normal and various disease states. A free radical profile similar to that observed in vivo after exposure to the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine is produced during simulation of enhanced oxidative stress (MPTP). To replicate the kinetics of a-syn that correlates to the neuropathology reported for the sporadic and hereditary types of Parkinson's disease, different model parameters of oxidative stress, UPP failure, or both routes are used. With the use of this in silico model, it is possible to evaluate the kinetics of pathway elements and more accurately identify and validate key pharmaceutical targets.
