What is the advantage to prokaryotes grouping related metabolic gene products into a single operon

1 answer:

7 0

The advantage to prokaryotes grouping related metabolic gene products into a single operon is they only needed one mRNA to create several gene products. This makes a prokaryote different to a eukaryote in terms of gene information processing. Prokaryotes have fewer genes. These genes are located in one chromosome only.

Adenylate cyclases (ACs) are the membrane-bound glycoproteins that convert ATP to cAMP and pyrophosphate.

sasho [114]

Adenylate cyclases (ACs) are the membrane-bound glycoproteins that convert ATP to cAMP and pyrophosphate.

When activated by G-protein Gs, adenylate cyclases (ACs), which are membrane-bound glycoproteins, catalyze the synthesis of cAMP from ATP.

Different AC isoforms are widely expressed in various tissues that participate in regulatory systems in response to particular stimuli.

Humans have 9 different AC isoforms, with AC5 and AC6 thought to be particularly important for cardiac activities.

Nitric oxide has an impact on the activity of AC6, hence the protein's nitrosylation may control how it works. However, little is known about the structural variables that affect nitrosylation in ACs and how they relate to G's.

We predict the cysteines that are prone to nitrosylation using this 3D model, and we use virtual ligand screening to find potential new AC6 ligands.

According to our model, the AC-Gs interface's Cys174 in G's and Cys1004 in AC6 (subunit C2) are two potential residues that could experience reversible nitrosylation.

A population of 100 tigers has 30 with horizontal stripes. Using pedigrees, you ascertain that horizontal striping is caused by

bixtya [17]

Assuming that this population is in Hardy-Weinberg equilibrium, we can sayt that the probability that, given enough time, all tigers in the population will have horizontal stripes is 30% = 0.3.

--------------------------

Available data:

Population size, N = 100 tigers
Number of Tigers with horizontal stripes = 30
Horizontal stripes is caused by an autosomal recessive mutation.

We need to know the probability that all tigers in the population will have horizontal stripes, which is the recessive phenotype.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of horizontal striped individuals in the population.

There are 100 individuals, and only 30 have horizontal stripes.

So, the phenotypic frequency, F(HS) is 30/100 = 0.3 = 30%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(hh) = 30%

Finally, we can get the allelic frequency by taking the square root of this value.

F(hh) = q² = 0.3

f(h) = q = √0.3 = 0.55 = 55%

According to these calcs, the probability for the fixation of the recessive allele is 55%, and the probability that all individuals express the recessive horizontal stripes phenotype is 30%.

State any two human activities that have a direct impact on soil formation

olganol [36]

Answer:

Nonetheless, some human activities have clear direct impacts. These include land use change, land management, land degradation, soil sealing, and mining. ... This in turn leads to loss of soil carbon and other nutrients and to changes in soil properties and in soil biodiversity.
