Question 3: dehydration synthesis

Answer:

(organic chem) a chemical reaction in which two molecules become covalently bonded to each other with the removal of a water molecule

Question 4: protein

Answer:

organic chem)a biologically functional molecule consisting of one or more polypeptides folded and coiled into a specific three-dimensional structure

Question 5: carboxyl terminus/C-Terminus

Answer:

(protein) a chemical group present in aldehyde and Ketones and consisting of a carbon atom double bonded to an oxygen atom

Question 6: 3'

Question 7: lipid

Answer:

(organic chem)any of a group of large biological molecules including fats phospholipids and steroids that mix poorly if at all with water

Question 8: double helix

Answer:

nucleic acids)the form of native DNA, referring to its two adjacent antiparallel polynucleotide strands wound around and the imaginary axis into a spiall shape

Question 9: peptide

Answer:

protein) they comes Island bond between the carboxyl group on one amino acid and the amino group on another, formed by a dehydration reaction

Question 10: polar

Answer:

a molecule such as water with an uneven distribution of charges in different regions of the molecule in one end of the molecule has a positive charge and on the other end has a negative charge the molecule is polar.(water)

Question 11: R group

Answer:

protein)sidechain specific to each amino acid that confers particular chemical properties to the amino acid

Question 12: hydrophobic

Answer:

(water) having no affinity for water tending to coalece and form droplets in water

Question 13: alpha helice

Answer:

protein)a coiled region constitution one form of the secondary structure of proteins, arising from a specific pattern of hydrogen bonding between atoms of the polypeptide backbone

Question 14: secondary structure

Answer:

protein

regions of repetitive coiling or folding of the polypeptide backbone of a protein due to hydrogen bonding between constituents of the backbone

Question 15: deoxyribose

Answer:

(nucleic acids) The sugar component of DNA nucleotides have anyone figured Hydro seal group then drive is there sugar component of RNA nucleotide.

Question 16: hydrogen bond

Answer:

a type of weak chemical bond in which is formed when the slightly positive hydrogen atom of a polar covalent bond forms and electrostatic link with the more electronegative atom of a (basic chem)

Question 17: cleavage

Answer:

this succession of Rapid cell division without significant growth during early development that converts the zygote to a ball of cells. The process by which the zygote rapidly divides without growing to become multicellular.(basic chem)

Question 18: synthesis

Answer:

Creation of something, the process of combining two or more components to reproduce an entity

Answer:

it's the smallest unit of matter the host the properties of an element(basic chem)

Question 20: subunit

Answer:

a single protein molecule that assembles with other protein molecules to form a protein complex.(organic chem)

Question 21: antiparellel- in regards to DNA

Answer:

nucleic acids)referring to the arrangement of the sugar phosphate Backbones in a DNA double helix.

Question 22: amino acid

Answer:

(protein) an organic molecule processing both a carboxyl and an amino group. Amino acids serve as the monomers of polypeptides

Answer:

(organic chem)A sugar (mono-saccharide) or one of its dimers (disaccharides) or polymers (polysaccharides)

Question 24: nucleic acid

Answer:

nucleics acids)a polymer consisting of many nucleotide monomers serve as a blueprint for proteins and through the actions of proteins for all cellular activities the two types are DNA and RNA
