The charge on a DNA molecule is negative, and the phosphate groups within the molecule's backbone are responsible for contributing to that charge.
DNA, or deoxyribonucleic acid, is a large molecule that carries genetic information essential for the growth, development, and reproduction of living organisms. Its structure consists of two strands, forming a double helix, held together by hydrogen bonds between the nitrogenous bases. Each strand is made up of repeating units called nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.
The backbone of a DNA strand is formed by alternating sugar and phosphate groups, connected through phosphodiester bonds. The phosphate groups within this backbone have a negative charge due to the presence of a dissociable hydrogen atom, which leaves behind an oxygen atom with an unshared pair of electrons. As a result, the DNA molecule as a whole carries a net negative charge.
This negative charge plays an essential role in the function of DNA. It allows for the formation of hydrogen bonds between complementary nitrogenous bases, contributing to the stability of the double helix structure. Furthermore, the negative charge on DNA interacts with positively charged proteins and other molecules in the cell, enabling crucial processes like DNA replication, transcription, and repair.

Sandia Inc. Wants to acquire a $360,000 computer-controlled printing press. If owned, the press would be depreciated on a straight-line basis over 10 years to a book salvage value of $0. The actual cash salvage value is expected to be $25,000 at the end of 10 years. If purchased, Sandia will incur annual maintenance expenses of $3,000. These expenses would not be incurred if the press is leased. If the press is purchased, Sandia could borrow the needed funds at an annual pre-tax interest rate of 10%. The lease rate would be $48,000 per year, payable at the beginning of each year. If Sandia has an after-tax cost of capital of 12% and a marginal tax rate of 40%, what is the net advantage to leasing? a.$65,543 b.$57,173 c.$37,737 d.$60,713
Answer:
c.$37,737
Explanation:
Present value of Cost of Buying = The Cost of Press + [(Post Tax annual maintenance expenses - Annual Depreciation Tax shield)*PVIFA (6%,10)] - [Post tax Salvage Value*PVIF (12%,10)]
PV of Cost of Buying = 360000 + (3000*(1-40%)-360000/10*40%)*7.360 - 25000*(1-40%) * 0.322
PV of Cost of Buying = $262,434
Present value of Cost of Leasing = Post tax Lease Payment at the Beginning *(1+PVIFA(6%,9))
PV of Cost of Leasing = $48000*(1-40%)*(1+6.802)
PV of Cost of Leasing = $224,697
Net advantage to leasing = PV of Cost of Buying - PV of Cost of Leasing
Net advantage to leasing = $262,434 - $224,697
Net advantage to leasing = $37,737

Answer:
interest = the amount earned on bonds or savings accounts
capital gains = the profit earned from selling a financial asset
dividend = the amount of money paid to share holders of a company
Explanation:
A capital gain is a financial term that is most often captured on tax returns when money is made above the face value or declared value of an asset or property that is sold.
When an individual 'purchases' a bond or places money into a savings account, that money is held in an "interest" baring account or grows over time. Savings account: A percentage is paid for holding those funds in a savings account based on the amount held. The financial institution where the funds are held, pays the owner a fee for use of said money that it is held. Those funds are called "interest" and are collected by the owner of those funds. A bond is typically purchased at a reduced face value amount. If the bond is held for a stated amount of time, the bond value reaches maturity after that time. Those gains are called interest and are typically captured on a 1099i form for tax purposes.
A dividend is a profit paid to a stockholder or investor of a company/business entity. Typically those funds are paid when a threshold of profits are reached by that company/business entity. Typically a dividend is captured on a 1099d form for tax purposes.
