QUESTION 13 Two chambers, X and Y, are separated by a semi-permeable membrane that allows water and urea, but not glucose, to pass through. At the start, chamber X contains a solution of urea in wate and chamber Y contains a solution of glucose in water. The molarity (measure of concentration) of urea in chamber X is the same number as the molarity of glucose in chamber Y. Which of the following will occur after sufficient time? O There will be overall diffusion of water from Y to X. O There will be no overall diffusion of water across the membrane. O There will be overall diffusion of water from X to Y.
DNA and RNA
Deoxyribonucleic acid (DNA) is usually called the blueprint of life. Deoxyribose is a monosaccharide that has a key function in the synthesis of deoxyribonucleic acid. One less oxygen-containing hydroxyl group occurs in deoxyribose sugar. Nucleic acid, deoxyribonucleic acid, is one of the natural components. Deoxyribonucleic acid is a double-stranded molecule. Watson and Crick postulated the double-stranded model of the helix. A deoxyribonucleic acid is a molecular group that carries and transmits genetic information from parents to offspring. All eukaryotic and prokaryotic cells are involved.
DNA as the Genetic Material
DNA, or deoxyribonucleic acid, is a long polymeric nucleic acid molecule discovered in the late 1930s. It is a polymer; a long chain-like molecule made up of several monomers connected in a sequence. It possesses certain characteristics that qualify it as a genetic component. Certain organisms have different types of nucleic acids as their genetic material - DNA or RNA.
Genetics
The significant branch in science which involves the study of genes, gene variations, and the organism's heredity is known as genetics. It is also used to study the involvement of a gene or set of genes in the health of an individual and how it prevents several diseases in a human being. Thus, genetics also creates an understanding of various medical conditions.
DNA Replication
The mechanism by which deoxyribonucleic acid (DNA) is capable of producing an exact copy of its own is defined as DNA replication. The DNA molecules utilize a semiconservative method for replication.
Diffusion of water across a semipermeable membrane from the higher water potential area to the lower water potential area is known as osmosis. Movement of water in living organisms occurs by this mechanism.
