Biochemistry

DNA contains the genetic instructions for building and maintaining living organisms. It is a molecule that stores genetic information, carries instructions for protein synthesis, and is involved in the regulation of gene expression. DNA ultimately determines an organism's traits and characteristics.

ATP synthase is the protein enzyme involved in chemiosmosis. It is responsible for generating ATP by facilitating the movement of protons across the inner mitochondrial membrane.

when your mom and your dad love each other alot, the limo parks in the garage and than realizes that its not in right so he must reverse and redo..he reapeats this about 3 times......than 9 months later a new limo is made

The nucleus contains thin strands of DNA known as chromatin. Chromatin is made up of DNA and proteins, and it packages the DNA to fit inside the nucleus of a cell.

Allosteric enzymes are mostly polymeric in nature i.e. they are made up of several subunits. These enzymes exhibit cooperativity i.e. binding of a ligand to the active site alters (increase or decrease) the binding affinity of the ligand on other sites. Some monomeric enzymes also exhibit cooperativity. Those monomeric enzymes which exhibit cooperativity are called mnemonical enzymes. Hexokinase D (an isoenzyme of hexokinase) is one such example.

The major cofactor formed from folate is tetrahydrofolate (THF). It plays a crucial role in transferring one-carbon units in various biochemical reactions, including nucleotide synthesis and amino acid metabolism.

Some gonadal adrenocortical hormones include testosterone, estrogen, and progesterone. These hormones are produced in the adrenal glands as well as the gonads (testes and ovaries), and they play key roles in regulating sexual development, fertility, and reproductive functions.

The only gonadal adrenocortical hormone is dehydroepiandrosterone (DHEA). DHEA is produced in both the adrenal glands and the gonads, and serves as a precursor to other sex hormones like testosterone and estrogen.

This phenomenon would be described as transcriptional repression. It involves the inhibition of transcription when a protein binds to specific regions of DNA, typically leading to a decrease in gene expression.

Water is a universal solvent, allowing it to dissolve many substances due to its polar nature. It has a high specific heat capacity, helping to regulate temperature in living organisms and environments. Water also exhibits strong cohesive and adhesive forces, enabling it to transport nutrients and waste within organisms, as well as facilitate capillary action in plants. Overall, water's unique chemical and physical properties make it essential for life on Earth.

Antidiuretic hormone (ADH) regulates fluid intake by stimulating the kidneys to reabsorb water back into the bloodstream instead of excreting it in urine. This helps to maintain proper water balance in the body by increasing water retention. When the body detects dehydration or high salt concentration in the blood, ADH is released to prevent excessive fluid loss and increase thirst sensation to encourage more fluid intake.

In cells, energy metabolism is regulated such that the rate of ATP supply pathways will balance the rate of ATP demand pathways. This regulation is done in such a way so that the ATP/ADP levels and the levels of other intermediates involved in respiratory pathways are kept with narrow ranges. This is important because even though the rate of ATP supply and demand can change by several orders of magnitude, the ATP/ADP remains almost unchanged. This is achieved by simultaneous regulation and some 'fine tuning" regulation of supply and demand pathways. For example in muscular contraction will increase the energy demand and increase in demand relative to supply will decrease the ATP/ADP ratio which can activate ATP supply pathways. This type of regulation alone is not sufficient cause as you see the ATP/ADP ratio has to decrease first before any change is made in supply pathways, and in cases where this is a large increase in ATP demand, this decrease will be substantial. So, simultaneous regulation by Ca2+ which is a signal for muscular contraction can activate both supply and demand at the same time so that little change in ATP/ADP ratio is needed and metabolic homeostasis can be achieved

Starch is a polysaccharide, not a disaccharide, as it is a polymer of many sugar units. A disaccharide would contain just two units (for example, sucrose).

The adrenal glands produce hormones such as adrenaline and cortisol that prepare the body for emergency situations. These hormones help increase heart rate, blood pressure, and blood sugar levels, preparing the body to fight or flee in response to stress or danger.

Adrenocorticotropic hormone (ACTH) is the tropic hormone that is suppressed by increased plasma levels of cortisol. Cortisol exerts negative feedback on the hypothalamus and pituitary gland, inhibiting the release of ACTH.

Vitamin B9, also known as folate or folic acid, is essential for the synthesis of nitrogenous bases in DNA and RNA. It plays a crucial role in cell division and growth, making it important for processes like DNA replication and repair. Deficiency in vitamin B9 can lead to impaired DNA synthesis and potential genetic mutations.

Humans and chimpanzees having similar DNA suggests a close evolutionary relationship between the two species. It indicates a common ancestor from which both humans and chimpanzees diverged millions of years ago. The similarity in DNA points to shared genetic heritage and biological similarities.

There are three nucleotide Bases for each codon, so the Answer is 72 bases.

Scientists often look to insert a new gene into a vector, such as a plasmid or a viral vector. Vectors are vehicles that can deliver the gene into a host organism's cells for expression and study.

The anticodon is a sequence of three nucleotides found on transfer RNA (tRNA) molecules. Its function is to base pair with a complementary codon on messenger RNA (mRNA) during translation. The location of the anticodon is within the loop region of the tRNA molecule.

A prokaryotic cell does not have cell organelles bound inside a nuclear membrane, i.e., it does not have a proper nuclear structure. It has a primitive nucleus.

On the contrary, a eukaryotic cell has a well developed nucleus with membrane bound organelles.

Adenine occurs in both RNA and DNA molecules. It is uracil that replaces thymine in the RNA molecule.

Mitochondria are not directly responsible for protein assembly. They are primarily involved in producing energy in the form of adenosine triphosphate (ATP) through cellular respiration. Protein assembly generally occurs in the ribosomes of a cell.

This mutation would cause a frameshift mutation, shifting the reading frame of the DNA sequence. Most likely, this would lead to a completely different protein being translated, resulting in a protein with a different sequence of amino acids from the original protein. The number of amino acids would depend on the specific changes in the protein sequence caused by the frameshift mutation.
