What is the function of the translocon in co-translational translocation of a membrane-bound protein?

1 answer:

7 0

The translocon (commonly known as a translocator or translocation channel) is a complex of proteins associated with the translocation of polypeptides across membranes.[1] In eukaryotes the term translocon most commonly refers to the complex that transports nascent polypeptides with a targeting signal sequence into the interior (cisternal or lumenal) space of the endoplasmic reticulum (ER) from the cytosol. This translocation process requires the protein to cross a hydrophobic lipid bilayer. The same complex is also used to integrate nascent proteins into the membrane itself (membrane proteins). In prokaryotes, a similar protein complex transports polypeptides across the plasma membrane or integrates membrane proteins.[2] Bacterial pathogens can also assemble other translocons in their host membranes, allowing them to export virulence factors into their target cells.[3]

How can an individual with a recessive genetic disorder have parents who are not afflicted?

jonny [76]

Both parents must be carriers, which means they have the heterozygous gene (one uppercase letter & one lower case letter). They will still carry that mutated gene (because they have a lower case letter), and their offspring will have a 25% chance of getting a recessive disorder. The percentage is low but still possible.

How does the size of the soil particles impact<br> the soil's permeability (movement of water)?

Usimov [2.4K]

Answer:

Water moves by gravity into the open pore spaces in the soil, and the size of the soil particles and their spacing determines how much water can flow in. Wide pore spacing at the soil surface increases the rate of water infiltration, so coarse soils have a higher infiltration rate than fine soils.

How does soil particle size affect permeability?

But permeability is a different thing. It increases as particle size increases. By definition, permeability is a MEASURE OF EASE with which fluids will flow though a porous rock, soil or sediment. ... That means capillarity increase as particle sizes decreases.

Chloe reads that given the correct conditions, cuttings from certain plants will form roots along the stem, enabling a new plant

Archy [21]

Answer:

The correct answer is - If you use the rooting hormone when cloning plants from cuttings, then it will be beneficial for the cuttings.

Explanation:

A hypothesis is a possible explanation or solution behind the particular natural world process or phenomenon. It is formed on the basis of the observation of the phenomenon or process, how it works or what characteristics it shows.

In this study, it is found that the root hormones promote the growth in the clonings from the cuttings of plants thus, the provided hypothesis is the correct hypothesis for the experiment given.

Here are the cases for you to solve remember that you just have to choose ONE of the following cases to discuss in your Case Stu

Zielflug [23.3K]

Answer:

It is known that the lungs and mouth are associated with a passage known as trachea. At the time of an infection, if there is a passage between the lungs and the mouth, the body makes a fluid known as sputum, also known as phlegm. By coughing the body is in real sense attempting to get rid of this phlegm.

The most general pathogens, which are found in Sputum culture are Haemophilus influenzae, Streptococcus pneumonia, Mycobacterium species, and Staphylococcus aureus. In the given case by observing the symptoms demonstrated by Navin, one can presume that Navin is suffering from Tuberculosis.

The disease is the result of Mycobacterium tuberculosis bacteria. These are the pathogenic bacteria, that comprise a mycolic acid on its cell surface. Due to the presence of this coating, it is tough to determine it with the help of Gram staining. Thus, Acid-fast staining, like Zehl-Neelsen is used.

These bacteria are aerobic in nature and need a huge concentration of oxygen, it mainly infects the respiratory system of the mammals, and generally spreads from infected persons via sneeze, coughing, talks, or laughing. Smoking is also a supplementary element of the condition. The major symptoms of the condition are weight loss, fatigue, severe cough, no appetite, chest pain, and night sweats.
