The right answer is James Watson and Francis Crick.

On April 25, 1953, Francis Crick and James Watson described for the first time in a study the structure of DNA (deoxyribonucleic acid), a molecule in the form of a double helix containing the genetic heritage of all life forms. It was with a single-page article published in the British scientific journal Nature that the two young researchers (Crick was 36 years old and Watson only 25) would upset the world of biology and genetics.

At the time, we already know DNA and, even if some scientists have had trouble accepting it, we know that it is the support of heredity. Studies have also already specified its chemical nature: a combination of nucleotides (phosphate - deoxyribose - nitrogenous base), assembled in long chains.

In which organelle are most molecules of ATP produced by the cell
SVEN [57.7K]

Answer:

Eukaryotic ATP production usually takes place in the mitochondria of the cell.

Explanation:

This ATP production by the mitochondria is done by the process of respiration, which in essence is the use of oxygen in a process which generates energy. Most of the ATP of a eukaryotic organism is made in the mitochondria during the last phase of cellular respiration that is called the electron transport chain (ETC). A mitochondrion is an organelle within a eukaryotic cell.

vfiekz [6]

The kidneys are a pair of bean-shaped organs on each side of your spine<span>, under your ribs and behind your belly. Each kidney is about 4 or 5 inches long, roughly the size of a large fist. It goes to the kidneys to extract water from the excretory system and put it back into the blood. Kidneys filter your blood. They eliminate wastes, control the body's fluid balance, and hang onto the right levels of electrolytes. All of the blood in your body passes through them quite a few times a day.</span>

Which of the following is an unsual nucleoside that is found in tRNA but not mRNA?
gizmo_the_mogwai [7]

Answer:

Inosine

Explanation:

  • Inosine the unusual nucleoside which is found in tRNA but not in mRNA.
  • Inosine is derived from the nucleoside adenosine, adenosine is present in mRNA, however in case of tRNA, there is deamination of adenosine and thus, inosine is formed.
  • The enzyme that is responsible for carrying out this reaction is called as tRNA A:34 deaminases, here the position 34 indicates that the deamination takes place at position 34 of the tRNA.
  • The formation of inosine is essential for the wobble base pairing to take place.
  • The formation of inosine takes place when the hypoxanthine attaches to a ribose ring with the help of the beta glycosidic bond.
