Answer: The correct answer is A) A+C=G+T

According to Watson and Crick base pairing-

In a double stranded DNA molecule, Adenine pairs with Thymine and Guanine pairs with Cytosine. This means that number of Adenine in one strand is equal to the number of thymine in the complementary DNA strand. Similarly, the number of Cytosine in one strand is equal to the number of Guanine in the complementary strand.

Thus, the total number of Adenine and Cytosine in one strand becomes equal to the total number of Guanine and Thymine in the complementary strand.

This can be mathematically written as- A+C = G+T

Thus, option A) is the right answer.

The answer is A. A + C = G + T

<h2>Further Explanation </h2>

DNA is an acronym for deoxyribonucleic acid or in Indonesian it is also called deoxyribonucleic acid. Its chemical structure is in the form of complex macromolecules consisting of 3 kinds of molecules, namely:

  • pentose sugar (deoxyribose)
  • phosphoric acid
  • nitrogen base.

The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints, recipes, or codes, because it contains the instructions needed to build other components of cells, such as proteins and RNA molecules.

James Dewey Watson (born in Chicago, April 6, 1928) is an American molecular biologist known primarily as one of the discoverers of the structure of DNA molecules. He received the Nobel Prize in Medicine with Francis Crick and Maurice Wilkins in 1962 for discovering the structure of nucleic acid molecules and their means for transferring information.

Francis Harry Compton Crick (born in Northampton, England, June 8, 1916 - died in San Diego, California, United States, July 28, 2004, at the age of 88) is a British biologist. In 1949 Francis obtained a Ph.D. at Cambridge University. In the early 1950s together with James Dewey Watson, he discovered the substance of the form of DNA. For his discovery, he won the Nobel Prize in Physiology or Medicine with Watson and M.H.F. Wilkins.

Discovery of the Structure of Human DNA

James Watson at that time was a young scientist. This Chicago-born man began working at the Cavendish Cambridge Laboratory in 1951. Meanwhile, Francis Crick is a physics graduate from University College London and has helped develop radar and magnetic mines during World War II. Crick also wrote a dissertation on the crystallography of X-ray hemoglobin when Watson began joining the laboratory. Inspired by the success of other scientists working with molecular models, Watson and Crick quickly collected several DNA models and tried to combine all the evidence they could gather. They used photographs from previous X-ray scientists and used microscopes. The result, they managed to find the structure of human DNA. Based on the crystal photo from Franklin, Crick and Watson solidified their theory of the structure of DNA, which states that the structure of DNA is in the form of a double-helix, or double spiral, twisting. The twisted spiral is a set of gene codes called 'Adenine / Adenine' (A), 'Thymine / Thiamine' (T), 'Guanine / Guanine' (G), and 'Cytosine / Cytosine' (C). They published their theory in the Journal of Nature, in 1953.

If two trucks have the same mass, but truck A is traveling 15 km/h, and truck B is traveling 30 km/h, what statement is true? Qu
Montano1993 [528]

Given that the two trucks have the same mass but different velocities, that is truck A is traveling 15 km/h and truck B is traveling 30 km/h,  hence  Truck B will have a greater stopping distance.

The reason why Truck B will have a greater stopping distance is because it speed is greater hence more distance to cover.

From the following expression

Speed = Distance/Time

Distance = Speed*Time

More on the kinetic Energy

Following from the given problem truck B will also have more kinetic energy because it velocity is more

Formula

KE= 1/2mv^2

Hence the more the velocity for a constant mass the greater the Kinetic energy

The eye is an organ.why?<br>Skin is an epithelial tissue.why?<br>​
Brilliant_brown [7]

Answer:

"The organs have blood vessels as well as the nerves in it, the organ is also present within the organ motif is also being executed in these organs. So as eye. Epithelial tissue helps in protection against the microbes so as skin having different layers."

Explanation:

Eye is an organ because, the organs have blood vessels as well as the nerves in it, the organ is also present within the organ motif is also being executed in these organs. Similarly, inside the eyeball there is an organ which is known as retina, with is connected with the neural and epithelial tissue which helps in detection of the light which enters into the eyeball.

Skin is an epithelial tissue because, epithelial tissue helps in protection against the microbes. Similarly skin is composed of different layers of epithelial tissue which is also supported by the layers of connective tissue, helps in protection of internal organs from damage as well as dehydration.
