Clue 1:

Answer:

The two problems that the transfer of information from DNA to protein must overcome are:

  • How to bring the information from the nuclear DNA to the place of protein synthesis?
  • How to convert this DNA information into amino acids and then into proteins?

Explanation:

The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.

<h3>How to bring the information from the nuclear DNA to the place of protein synthesis? </h3>

The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.

<h3>How to convert this DNA information into amino acids and then into proteins?</h3>

Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.

A deficiency of which molecule will trigger lactic acid buildup in our muscles? ATP Carbon dioxide Oxygen Water
ValentinkaMS [17]
Oxygen, neccessary for cellular respiration, is the answer. As oxygen becomes scarce, your cells begin to aerobically produce very little ATP, in effect fermenting and producing lactic acid.

3. All of the organic molecules are based on which element?
Ulleksa [173]

Answer:

<h2><u>Carbon</u><u>.</u><u> </u></h2>

Explanation:

<em>Life is based on carbon; organic chemistry studies compounds in which carbon is a central element. The properties of carbon make it the backbone of the organic molecules which form living matter. Carbon is a such a versatile element because it can form four covalent bonds.</em>

Describe the type of plants that serve as pioneer species, intermediate species, and climax community species in secondary succe
MissTica
In secondary succession, the pioneer species are plants that are adapted to exploit disturbances rather than bare rock. They typically include plants such as grasses, birch trees, and fireweed. Organic matter from the pioneer species improves the soil so other trees and plants can move into the area.

Meat is not a good source of protein because it does not provide the body with all the essential amino acids.
tankabanditka [31]

Answer: False.

Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.

These are-  Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.

Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.
