Answer:

Many cell cycle control factors, mainly cyclins, cyclin-dependent kinases (Cdks) and cyclin-dependent kinase inhibitors (CKIs). Cyclins and Cdks activate cell cycle factors that are essential for the start of the next cell cycle phase.

The cell cycle is controlled by many cell cycle control factors, namely cyclins, cyclin-dependent kinases (Cdks) and cyclin-dependent kinase inhibitors (CKIs). Cyclins and Cdks, which are positive regulators of the cell cycle, activate cell cycle factors that are essential for the start of the next cell cycle phase.

Some bacteria viruses parasites and fungi can cause an illness. these are known as?

yawa3891 [41]

Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites.

<h3>What are viruses bacteria and parasites?</h3>

Viruses, bacteria, and parasites live organisms that are found all around us. they're in water and soil. they're on the surfaces of foods that we eat. they're also on surfaces that we touch, like Counter top in the bathroom or kitchen. Some bacteria sleep in and on our bodies and don't cause problems.

<h3>Which are infectious diseases?</h3>

The flu, measles, HIV, streptococcal sore throat , COVID-19 and salmonella are all samples of infectious diseases. Cancer, diabetes, congestive coronary failure and Alzheimer's disease are all examples of noninfectious diseases.

What are the causes of disease?

Similarly, diseases are caused by different microorganisms and may be classified as diseases caused by bacteria, fungi, viruses etc. Some diseases also are caused by multicellular organisms such as worms.

Fittoniya [83]

They use cognitive biases like framing, loss aversion, status quo etc. to elicit an emotional response in hopes of you making impulsive purchases.

You can use skepticism by listening more carefully to what is being said and looking up any claims made by the advertiser. Like if they say they are the cheapest car insurance, you don't just believe them you compare prices.

Why is it difficult for scientist to find fossils from the pre-Cambrian period

mojhsa [17]

Because Precambrian rocks are in short supply, hence fossil evidence is harder to find.they only discovers sections of some Precambrian rocks there were no bones or shells to be permineralized.

In sickle-cell disease, as a result of a single amino acid change, the hemoglobin tetramers associate with each other and assemb

Phoenix [80]

Answer:

One of the common genetic disorders is sickle cell anemia, in which 2 recessive alleles must meet to allow for destruction and alteration in the morphology of red blood cells. This usually leads to loss of proper binding of oxygen to hemoglobin and curved, sickle-shaped erythrocytes. The mutation causing this disease occurs in the 6th codon of the HBB gene encoding the hemoglobin subunit β (β-globin), a protein, serving as an integral part of the adult hemoglobin A (HbA), which is a heterotetramer of 2 α chains and 2 β chains that is responsible for binding to the oxygen in the blood. This mutation changes a charged glutamic acid to a hydrophobic valine residue and disrupts the tertiary structure and stability of the hemoglobin molecule. Since in the field of protein intrinsic disorder, charged and polar residues are typically considered as disorder promoting, in opposite to the order-promoting non-polar hydrophobic residues, in this study we attempted to answer a question if intrinsic disorder might have a role in the pathogenesis of sickle cell anemia. To this end, several disorder predictors were utilized to evaluate the presence of intrinsically disordered regions in all subunits of human hemoglobin: α, β, δ, ε, ζ, γ1, and γ2. Then, structural analysis was completed by using the SWISS-MODEL Repository to visualize the outputs of the disorder predictors. Finally, Uniprot STRING and D2P2 were used to determine biochemical interactome and protein partners for each hemoglobin subunit along with analyzing their posttranslational modifications. All these properties were used to determine any differences between the 6 different types of subunits of hemoglobin and to correlate the mutation leading to sickle cell anemia with intrinsic disorder propensity.
