longitude lines meet
Explanation:
Answer:
Molecular chaperons in the cells helps in protein folding. These are the group of proteins that have functional similarity and they also assist protein folding.
They have the ability to prevent the non specific binding and aggregation by the binding of the non native proteins.
Molecular chaperons helps in recognizing the hydrophobic surfaces of the unfolded proteins because they themselves are hydrophobic in nature and will combine to the hydrophic binding and bonding.
This helps in guiding the protein to folding.
Answer
When a eukaryotic cell is not undergoing mitosis, the DNA and its associated proteins appear as a visible network of dark fibers called the Chromatin.
Definition
Chromatin is a thread like structure that can be seen inside nucleus before cell division. It is a complex of DNA and histone proteins.
Forms of chromatin
Chromatin exist in two forms, that is
a. Euchromatin
It is less condensed and can be easily transcribed.
b. Heterochromatin
It is highly condensed and not transcribed as easy.
Organization of chromatin
Microscopy has shown the appearance of chromatin as beads on a string. The beads are called nucleosomes.
Nucleosome
Each nucleosome is composed of DNA wrapped around eight histone proteins. The nucleosome is then wrapped into a 30nm spiral called solenoid.
The environment selected is favorable to ponies with longer legs.
solution:
The relative constancy of the body or the ability to maintain an iptimim internal environment is called homeostasis.
Homeostasis, refers to stability, balance, or equilibrium. Physiologically, it is the body’s attempt to maintain a constant and balanced internal environment, which requires persistent monitoring and adjustments as conditions change. Adjustment of physiological systems within the body is called homeostatic regulation, which involves three parts or mechanisms:
1. the receptor
2. the control center
3. the effector
The receptor receives information that something in the environment is changing. The control center or integration center receives and processes information from the receptor. The effector responds to the commands of the control center by either opposing or enhancing the stimulus. This ongoing process continually works to restore and maintain homeostasis. For example, during body temperature regulation, temperature receptors in the skin communicate information to the brain (the control center) which signals the effectors: blood vessels and sweat glands in the skin. As the internal and external environment of the body are constantly changing, adjustments must be made continuously to stay at or near a specific value
.
Thus this is the required answer.
