Nucleic Acids - Biology Junction

Synthesis of the aromatic amino acids begins with the synthesis of chorismate - an important intermediate for many biosynthetic pathways. Phosphoenol pyruvate and erythrose 4-phosphate serve as beginning substrates for the pathway. A price of one NADPH + H+ and one ATP is exacted for every chorismate formed. In the sixth step of the synthesis another phosphoenol pyruvate molecule is added to the growing molecule.

Whey Protein Concentrate (WPC) - VPA


tRNA
Delivers
amino acids
that will be used by the
ribosomes
to assemble a protein
Anticodon
each
tRNA
molecule contains a complementary
triplet

of nitrogenous bases known as an anticodon.
DNA
THE PROCESS IN WHICH DNA MAKES AN EXACT COPY OF ITSELF IS REPLICATION
Small subunits that make up dna molecules are called nucleotides
- 3 parts ( sugar, phosphate, & nitrogen base )
dna is found in the nucleus
the sugar found in dna is deoxyribose
molecules responsible for unlining and opening up a dna molecule for replication is dna helicase
RNA
-molecules responsible for undwinding and opening up a dna molecule for transcription is rna polymerase

Transcription & Translation
organelles involved
Ribosomes: manufacture proteins using info provided by the DNA of the nucleus
Two Types: Free ribosomes : scattered throughout the cytoplasm, and the proteins they manufacture enter the cytosol
Fixed Ribosomes: attached to endoplasmic reticulum
Transcription
1.)
2 DNA
strands seperate -
RNA
polymerase binds
2.) RNA polymerase moves from one
nucleotide
to another along the length of the gene at each site complementary RNA nucleotides form
hydrogen bonds
w/ the DNA nucleotides of the
gene

Translation
the process of peptide formation using the info from
mRNA
-translation begins when newly
synthesized
mRNA leaves the nucleus and binds with
a ribosomes
in the
cytoplasm

Pineapple is an excellent source of the (brain) anti-inflammatory, BROMINE, which also displays . This preconditioning actually begins before and during pregnancy. It is reported that smoking and second-hand smoke may inhibit proper brain development, especially in the , leading to aggressive behavior plus neurological and cognitive disorders. Shaking a baby or something as simple as allowing a young child to repeatedly rock back and forth in a Fisher Price or other stationary baby seat, instead of a walker, can also lead to pre-frontal cortex damage, which can lead to . Many nutrients are severely lacking in commercially prepared baby foods due to , preparation and processing techniques, and manufacturers withholding foods due to concerns of (a lawsuit from) an . It is extremely important to breastfeed an infant to transfer immunities. Pregnant and lactating women might wish to avoid hydrogenated foods, especially those containing hydrogenated peanut butter and oils, because the fats have been broken up into smaller molecules to make the product more appealing to the consumer, and useful to food processing companies. The smaller molecules of hydrogenated peanut oil have been found in breast milk, and may contribute to peanut allergies later in life. A McDondalds™ "Filet-O-Fish" sandwich, which is cited in an , may sound nutritious, but 46% of the calories are from fat, 39% are from carbohydrates, and 15% are from protein, with an additional helping of hydrogenated, trans-fat producing oils, plus a foaming agent. This is not a healthy meal according to the FDA, so beware of foods you don' prepare yourself. Skin is the largest organ of the human body. Be careful what you put on it. Children who have been given SOY, a member of the legume family, along with peanuts, develop peanut allergies at a rate of about 3 times greater than the average (). Following this same principle, cornstarch or other food-based products and creams should not be applied to a child's skin whose immune system is in "training." To prevent allergies, anything that comes in contact with a child's skin, or fed to infants less than 6 months old (because of ""), should be carefully scrutinized. A "no fat" or "extremely low fat" diet is dangerous for an infant or toddler. It is extremely important to frequently offer your child WATER rather than a sugar or artificial sweetener-based drink. For children over 6 months of age (post "open gut"), long-chain fatty acids (Omega 3, et), such as found in fish oil, are a necessity for a healthy and intelligent child and adult. The lack of iron supplementation in non-breastfed infants given cow's milk, can lead to cognitive and motor skill impairment. What applies to an adult for a long life, does not apply to an infant.
An adult should:
Eat like a King in the morning
Eat like a Lord at noon
Eat like a Pauper in the evening for Colorado State University's recommendations for feeding young children. for Colorado State University's recommendations for Nutrition Resources Online Fact Sheets. Reducing or eliminating foods and beverages containing simple sugars and "high fructose" is mandatory. Stick to medium to low foods to help avoid diabetes, cardiovascular disease, cancer, and more. A caregiver must also provide the child with a hygienic environment, free from heavy metals, pesticides, airborne pathogens (especially fungi []), which is also mentally stimulating, and physically challenging. Keep in mind that the child is usually closer to the floor, where they are usually colder in the summer because of air conditioning, and much colder in the winter. Never put an infant on a carper or padding that has ever been wet for a sustained period - you don't want an infant inhaling mold spores in the carpet. Never put a child on a floor that has been treated for fleas or sprayed with a pesticide. Some harmful pesticide residues last for years. Always wash a child's clothes and bedding to remove toxic FIRE RETARDANT chemicals, before allowing the child to get near these items.
