Bold highlighted items in my cheat sheet represent the Normal Type Of Balance For an Account - Debit or Credit The purpose of my cheat sheet is to serve as an aid for those needing help in determining how to record the debits and credits for a transaction. My "Cheat Sheet" Table begins by illustrating that source documents such as sales invoices and checks are analyzed and then recorded in Journals using debits and credits. These Journals are then summarized and the debit and credit balances are Posted transferred to the General Ledger Accounts and the amounts are posted to the left side of the general ledger accounts for debit balances and to the right side of the general ledger accounts for credit balances. At the end of a year periodthe revenue and expenses accounts Ma's Kids are set to zero and their balances are transferred to a permanent equity account in the Balance Sheet such as Owner's Capital Mom or Retained Earnings.

A C The intrinsically bent structure is induced by the 'propeller twist' of base pairs relative to each other allowing unusual bifurcated Hydrogen-bonds between base steps.

At higher temperatures this structure is denatured, and so the intrinsic bend, is lost. All DNA which bends anisotropically has, on average, a longer persistence length and greater axial Double entry journal example.

This increased rigidity is required to prevent random bending which would make the molecule act isotropically. Circularization[ edit ] DNA circularization depends on both the axial bending stiffness and torsional rotational stiffness of the molecule.

For a DNA molecule to successfully circularize it must be long enough to easily bend into the full circle and must have the correct number of bases so the ends are in the correct rotation to allow bonding to occur.

Having a non integral number of turns presents a significant energy barrier for circularization, for example a When DNA is in solution, it undergoes continuous structural variations due to the energy available in the thermal bath of the solvent.

This is due to the thermal vibration of the molecule combined with continual collisions with water molecules. For entropic reasons, more compact relaxed states are thermally accessible than stretched out states, and so DNA molecules are almost universally found in a tangled relaxed layouts.

For this reason, one molecule of Double entry journal example will stretch under a force, straightening it out. Using optical tweezersthe entropic stretching behavior of DNA has been studied and analyzed from a polymer physics perspective, and it has been found that DNA behaves largely like the Kratky-Porod worm-like chain model under physiologically accessible energy scales.

Phase transitions under stretching[ edit ] Under sufficient tension and positive torque, DNA is thought to undergo a phase transition with the bases splaying outwards and the phosphates moving to the middle.

What is 'Double Entry'

These structures have not yet been definitively characterised due to the difficulty of carrying out atomic-resolution imaging in solution while under applied force although many computer simulation studies have been made for example [39][40].

Proposed S-DNA structures include those which preserve base-pair stacking and hydrogen bonding GC-richwhile releasing extension by tilting, as well as structures in which partial melting of the base-stack takes place, while base-base association is nonetheless overall preserved AT-rich.

Supercoiling and topology[ edit ] Main article: The helical aspect of the DNA duplex is omitted for clarity. But many molecular biological processes can induce torsional strain. A DNA segment with excess or insufficient helical twisting is referred to, respectively, as positively or negatively supercoiled.

DNA in vivo is typically negatively supercoiled, which facilitates the unwinding melting of the double-helix required for RNA transcription. Within the cell most DNA is topologically restricted. DNA is typically found in closed loops such as plasmids in prokaryotes which are topologically closed, or as very long molecules whose diffusion coefficients produce effectively topologically closed domains.

Linear sections of DNA are also commonly bound to proteins or physical structures such as membranes to form closed topological loops. Francis Crick was one of the first to propose the importance of linking numbers when considering DNA supercoils.

In a paper published inCrick outlined the problem as follows: In considering supercoils formed by closed double-stranded molecules of DNA certain mathematical concepts, such as the linking number and the twist, are needed.

The meaning of these for a closed ribbon is explained and also that of the writhing number of a closed curve. Some simple examples are given, some of which may be relevant to the structure of chromatin.

It is an integer for a closed loop and constant for a closed topological domain.

This will normally tend to approach the number of turns that a topologically open double stranded DNA helix makes free in solution: This results in higher order structure of DNA. A circular DNA molecule with a writhe of 0 will be circular. If the twist of this molecule is subsequently increased or decreased by supercoiling then the writhe will be appropriately altered, making the molecule undergo plectonemic or toroidal superhelical coiling.

When the ends of a piece of double stranded helical DNA are joined so that it forms a circle the strands are topologically knotted. This means the single strands cannot be separated any process that does not involve breaking a strand such as heating.

The task of un-knotting topologically linked strands of DNA falls to enzymes termed topoisomerases. These enzymes are dedicated to un-knotting circular DNA by cleaving one or both strands so that another double or single stranded segment can pass through.

This un-knotting is required for the replication of circular DNA and various types of recombination in linear DNA which have similar topological constraints. The linking number paradox[ edit ] For many years, the origin of residual supercoiling in eukaryotic genomes remained unclear.

This topological puzzle was referred to by some as the "linking number paradox".Double-Entry Journal Instructions What's the purpose of a double-entry journal? The purpose of double-entry journal (DEJ) is to give you an opportunity to express your thoughts and become more involved with the material you encounter.

Nov 07,  · The general ledger. In double-entry bookkeeping, you post journal entries to your general general ledger reflects your financial activities.
