Biochemistry
Biochemistry is the study of the structure, composition and chemical processes in all living organisms. It covers the structures and functions of various cellular components, including proteins, carbohydrates, nucleic acids, lipids, and other biomolecules.

What is the process called when dna is exchanged between two bacteria via cytoplasmic bridges?
The process is called conjugation. It involves the transfer of genetic material, usually in the form of plasmids, from one bacterium to another through a tube-like connection called a pilus. This allows for the exchange of beneficial traits, such as antibiotic resistance genes, between bacteria.
Yes it is a hormone of pitutory.It stimulates production of hormones by thyroid.
What composes the primary structure of the Cell membrane?
The Cell membrane is primarily composed of a lipid bi-layer, two layers of lipids with the hydrophyllic {fatty acid} acid 'heads' on the bi-lateral external surfaces, while the bi-lateral hydrophobic 'fatty' tails co-exist happily on the interiorof the bi-lipid layer.
Bacteria possess a protective Cellulosic Cell Wall exterior to their Cell membranes, while Eukaryotic Cells utilize a Glyco-Protein Cell Coat to accomplish the same Functions.
The Cell membrane contains all of the Biochemically Active 'Trans-Membrane Proteins'.
Be sure that the Composition, and Production, of both [of] the Cell Walls and the Cell Coats are Enzymatically Regulated [aka Controlled].
Are both the egg and zygote of a sea star the same size?
No, the egg of a sea star is typically larger than a zygote. After fertilization, the zygote undergoes cleavage divisions, resulting in smaller cells before developing into a larva.
What do you call the procedure draining a blood from the kidney?
The procedure of draining blood from the kidney is called a renal biopsy. It involves removing a small sample of kidney tissue for analysis and diagnosis.
Can Hydrolysis of simple lipids require an enzyme?
Yes, hydrolysis of simple lipids requires enzymes such as lipases. Lipases help break down lipids into fatty acids and glycerol through a hydrolysis reaction. Without the presence of these enzymes, hydrolysis of simple lipids would not occur efficiently.
What pituitary hormone necessary to govern metabolism?
Thyroid-stimulating hormone (TSH) is a pituitary hormone that controls metabolism by stimulating the thyroid gland to produce thyroid hormones, which regulate the body's metabolic rate.
What type of organic marcomolecule is formed by polymerizaion reactions between amino acids?
Proteins are organic macromolecules formed by polymerization reactions between amino acids. These amino acids are linked together by peptide bonds to form long chains, which fold into complex three-dimensional structures to perform a variety of functions in living organisms.
No, the distal tubule and collecting ducts are not impermeable to water in the absence of hormones. These segments of the nephron regulate water reabsorption based on hormonal signals, particularly antidiuretic hormone (ADH). When ADH is present, water channels called aquaporins are inserted into the tubule walls, allowing for increased water reabsorption.
How do parts of the leaf help with photosynthesis?
The cells in the leaf called chloroplasts contain chlorophyll, a pigment that absorbs sunlight. The stomata in the leaf allow for the exchange of gases, such as carbon dioxide and oxygen, needed for photosynthesis. Veins in the leaf deliver water and nutrients to the cells involved in photosynthesis.
Why is it important to understand the perspective from which a story is told?
Understanding the perspective from which a story is told is important because it influences the way events are portrayed, characters are developed, and themes are presented. Different perspectives can offer unique insights, add depth to the narrative, and help readers or listeners interpret the story in a more nuanced way. It also allows us to appreciate the diversity of experiences and viewpoints, promoting empathy and understanding.
How many people are added to the DNA database every year?
It varies by country and organization, but millions of individuals are added to DNA databases annually around the world. This number continues to grow as more law enforcement agencies and research institutions collect genetic information for various purposes.
Why is cutting DNA into small pieces that can be sequenced is accomplished by?
Cutting DNA into small pieces is accomplished by using restriction enzymes, which recognize specific DNA sequences and cut the DNA at or near those sequences. This process results in smaller fragments that can then be sequenced using various sequencing techniques.
What alkalai objects are in the house?
Some examples of alkaline objects commonly found in a household are baking soda, soap, and certain cleaning products. These items have a high pH level and are used for various purposes like cleaning, cooking, and personal hygiene.
Does chewing tobacco give a false DNA test?
Chewing tobacco can potentially affect the result of a DNA test by contaminating the sample with DNA from the tobacco residue. This could lead to inaccurate results or difficulties in interpreting the test. It is recommended to avoid using tobacco products before providing a DNA sample.
What would happen to an organism that lost or never had the ability to replicate its DNA?
An organism that lost the ability to replicate its DNA would be unable to reproduce and pass on its genetic material to offspring, leading to its eventual extinction. If an organism never had the ability to replicate its DNA, it would not be able to grow, develop, or carry out essential biological functions necessary for survival.
When the chromosomes make an exact copy of themselves what are they then called?
When chromosomes make an exact copy of themselves, they are called sister chromatids. Sister chromatids are identical copies of a chromosome that are held together by a structure called the centromere.
What is a macromolecule and the four basic macromolecule?
A macromolecule is a large molecule made up of smaller subunits known as monomers. The four basic types of macromolecules found in living organisms are carbohydrates, lipids, proteins, and nucleic acids. Each plays a vital role in various biological processes within cells.
Biochemistry is just like that; different Tissue types have a wild [and wide] variety of these parameters - some Tissues do this while other Tissues do that.
Wide refers to the vast complexity of Biochemistry, while Wild refers to the inevitable Results of Mutations.
No, not as it is; yet it is becoming increasingly evident that, by Our Laboratory Hi-Jinks, many examples of otherwise 'Determined Cells' may be Biochemically Reverted to a "pluripotent" State.
What federal agency compiles DNA profiles?
The Federal Bureau of Investigation (FBI) manages the Combined DNA Index System (CODIS) program, which compiles DNA profiles from convicted offenders, crime scenes, and missing persons. This database is used by law enforcement agencies to help solve crimes and identify suspects.
Yes, Glycine is amphoteric. It can act as an acid or as a base (or alkaline).
What is the molecular weight of fenol?
Phenol.
C6H5OH
6 carbon atoms = 72.06 grams
6 hydrogen atoms = 6.048 grams
1 oxygen atom = 16.0 grams
===========================add
= 94.108 grams per mole

Why does sodium chloride have a very high melting point but ice has a low melting point?
Sodium chloride is an ionic compound that has a crystalline structure. Each sodium ion (Na+) interacts with 6 chloride ions (Cl-) on each side of it, and each Cl- interacts with the 6 Na+ around it. In a single salt crystal, there are millions and millions of ionic bonds. To melt an ionic material, you have to break each of those ionic bonds. Ionic bonds are not that weak, and when you try to break all of them it takes a lot of energy! Ionic compounds are different than molecular ones in this way. To melt ice, for instance, you don't have to break the bonds in water, you just have break the much weaker attractive forces between two water molecules that are next to each other (called intermolecular forces). These types of attractive forces are much easier to breaker than ionic bonds, and so most molecular compounds have lower melting point than do ionic ones. Most ionic compounds have very very high melting points in fact.
