Which element is found in nucleic acids but not in proteins?

Answers

Answer 1
Answer:

Phosphorus is the element found in nucleic acids but not in proteins.

Further Explanation

Proteins  

  • Proteins are one of the major biomolecules that exists in nature.
  • They are made of amino acids which are the building blocks. Amino acids contain four different elements which include;
  1. Hydrogen  
  2. Oxygen  
  3. Nitrogen
  4. Carbon
  5. Some amino acid contains sulfur element.

Nucleic acids

  • Nucleic acids are one of the four major bio-molecules in nature. Nuclei acids is divided into two; RNA and DNA.
  • The building blocks of nucleic acids are Nucleotide bases which are made by a nitrogenous base, a sugar and a phosphate group.

DNA  

  • DNA is a nuclei acid that is responsible for carrying genetic information in living organisms.
  • It is through DNA that genetic information is passed from one organism to another through the process of DNA replication.
  • Additionally, it carries the information that is used to make proteins which performs various functions in living cells.
  • Each Nucleotide in DNA contains a nitrogenous base, a deoxyribose sugar, and a phosphate group.
  • DNA molecules are made up of nitrogenous bases; Adenine, Guanine, Cytosine and Thymine.

RNA

  • Ribonucleic acid (RNA) is a type of nucleic acid, a molecule that plays a major role in the flow of information from the DNA to the proteins. For a gene to be expressed information has to be passed through the RNA.
  • Each nucleotide in RNA contains a nitrogenous base, a ribose sugar, and a phosphate group.
  • Nitrogenous bases in RNA includes; Adenine, Guanine, Cytosine and uracil. Thymine in DNA is replaced with Uracil.

Answer 2
Answer:

The element is found in nucleic acids but not in proteins are the Phosphorous.

Nucleic acids are polynucleotides, which are long chainlike polymers made up of essentially identical nucleotide building components. Each nucleotide is made up of a nitrogen-containing aromatic base that is linked to a pentose (five-carbon) sugar, which is then linked to a phosphate group.

Proteins are composed of hundreds or thousands of smaller units known as amino acids that are linked together in lengthy chains. A protein is made up of 20 different types of amino acids that can be mixed. The sequence of amino acids determines each protein's distinct three-dimensional structure and function.

Thus, Phosphorous is the element which is found in nucleic acid but not in proteins.

D. an unprovoked attack on the U.S.

Answers

"Nationalism in the Balkans" is the one among the following choices given in the question that has been mentioned by historians as a cause of World War I. The correct option among all the options that are given in the question is the first option or option "A". I hope the answer has come to your help.

Answer:

Option A, nationalism in the Balkans

Explanation:

Eastern Europe cluster of nations lying between the Austro-Hungarian and Ottoman empires was known as Balkans. Due to its strategic location, all the Europeans powers focused on Balkans’ event. Also,  the Balkans were  politically active as they had both national ethnicity and tension with in its national territories.  

In 1912, several Balkan nations  became part of military alliances as influenced by the Russians which later on led to the  formation of the Balkan League. This Balkan league waged several wars against the Ottomans in order to remove them from eastern Europe. After fighting for eight months, Balkan won this battle but they were disrupted and thus Serbian nationalist groups and led to World War I

Hence, option A is correct

In neuronal communication, ________ involves moving a neurotransmitter from the synapse back into the axon terminal from which it was released.

Answers

Answer:

In neuronal communication, _reuptake_ involves moving a neurotransmitter from the synapse back into the axon terminal from which it was released

Reuptake is the reabsorption of a neurotransmitter by a neurotransmitter located along an axon terminal's plasma membrane (i.e., the pre-synaptic neuron at a synapse) or glial cell after performing its role of transmitting a neural impulse.

The cell cycle consists of two main phases: _____. interphase and M phase G0 phase and S phase M phase and S phase interphase and G2 phase

Answers

Answer: The correct answer is -

interphase and M phase.

Explanation:

Cell cycle can be described as a series of events that take place for the division of cell into two daughter cells.

It is primarily divided into two stages, which are-

1) Interphase (that is further divided into G1, S, and G2 phase) that involves the duplication of DNA and other proteins required in cell division.

2) M (mitotic phase) phase during which the nuclear division takes place through four successive stages that are prophase, followed by metaphase, anaphase and telophase.

After this cytokinesis (cytoplasmic division) occurs resulting in formation of two daughter cells.

Thus, first option is the right answer.

Interphase and M phase (Mitotic phase).

Interphase is when the cell is resting and preparing for division, M phase is when the cell is in the process of dividing.
