Answer:

DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are. Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.

PLEASE HELP!! “Place the events of the construction of proteins in the correct order.”
Alik [6]

Answer:

The correct order of events of protein synthesis would be from the properties of DNA to forming of polypeptide chain. The correct order would then be B, A, E, D, C.

The following are the correct order of events of translating genetic information on a DNA:

transcription: information of a DNA is transcribed into mRNA in the nucleus.

the mRNA is moved from the nucleus to the ribosome.

amino acids attached to tRNAs are also moved to the ribosome.

the message on the mRNA is translated with the tRNA dropping the amino acid corresponding to the codons on the mRNA and individual amino acids are joined by polypeptide bonds.

Continued strenuous activity can cause lactate to accumulate in muscles. After the activity stops, the lactate is converted into
kotykmax [81]

The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori,[1] refers to the metabolic pathway in which lactate produced by anaerobic glycolysis in the muscles moves to the liver and is converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.[2]

Proteoglycans are part of the extracellular matrix; they provide structure, viscosity and lubrication, and adhesiveness. They ar
ankoles [38]

Answer:

This question lacks options, options are:  a. beta-D-fructofuranose b. amylose c. uronic acid d. N- acetylglucosamine. The correct answers are c and d.

Explanation:

Glycosaminoglycans are very long, unbranched polysaccharides, made up of repeating units of disaccharides. One of the disaccharides is always an amino sugar, which can be N- acetylglucosamine. The other is uronic acid (it can be iduronic acid or glucuronic acid and is often sulfated at position 2). The amino sugar is usually sulfated and the rest of the sugars have carboxyl groups, which give the structure a negative charge, which attracts a large amount of cations such as sodium. Glycosaminoglycans are often covalently bound to proteins to form proteoglycans. Hyaluronic acid is the only glycosaminoglycan that does not form protein bonds and does not have sulfate groups in its structure.
