Answer:

-RNA molecule.

Explanation:

Reverse transcriptase or RT can be defined as an enzyme that synthesizes cDNA (complementary DNA) molecules by using RNA molecule as template. This process is known as reverse transcription.

Reverse transcriptase enzyme is found in many RNA viruses, prokaryotes and eukaryotes. Telomerase in an example of reverse transcriptase, which is found in eukaryotes and replicates ends of linear chromosomes.

Thus, the correct answer is 'RNA.'

Answer:

Bro..The enzymes are encoded and used by viruses that use reverse transcription as a step in the process of replication...I know that much...

How does distance affect the strength of the force of gravity ?

pogonyaev

The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.

None of the other options would change as a result of just cutting a cork into smaller pieces

9. A. The luggage will be lighter to carry

The weight of water can add up very quickly so when you remove almost 90% of water from a substance, you can substantially decrease the weight

10. A. behind him

The sun is shining on his back so his shadow is in front of him, but if he were to turn around his shadow would still be in the same place in relation to his body

The CFTR protein is made up of 1,480 amino acids linked together in a chain. Some

weqwewe [10]

Answer:

The answer is D) It will affect the primary, secondary, and tertiary structures of the CFTR protein.

Explanation:

The deletion of phenylalanine (F) in position 508 or F508, disrupts the sequence of amino acids and polypeptides, as seen in the primary structure.

It also affects the secondary structure since it can alter the folding or kinks of the alpha-helices or beta-sheets of the local polypeptide chain.

For the tertiary structures, it will affect the overall shape of the CFTR protein, and ultimately, alter its function in the body which is to produce thin, free-flowing mucus in the respiratory, digestive, and reproductive system, etc.

<h3>What is the CFTR Protein?</h3>

Normally, the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein functions as a membrane channel protein that transports negatively-charged ions, such as chloride ions, in and out of the cell. It also transports water which is used to form thin, free-flowing mucus seen in the respiratory, digestive, and reproductive systems. It can also influence other channels to regulate the entry of sodium ions across plasma membranes seen in the pancreas and lungs.

The CFTR protein mutation found in Cystic Fibrosis (CF) is present in almost 70% of CF patients. The mutation alters the structure of the chloride ion channel and movement of chloride ions and water in and out of the cell. Thus, impairing the production of mucus, which is characteristically sticky and thick seen in Cystic Fibrosis.
