Normal cells responds to contact inhibition. When they come into contact with other cells, they stop moving and dividing. This k

eeps the cell contained within their own tissues. How did the mutated (cancer) cells show the evidence that they do not respond to contact inhibition?

Answer:

Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.

1) Cuál es la diferencia que existe entre sustitución, Inserción y deleción en las mutaciones
marysya [2.9K]

Answer:

See the answer below please.

Explanation:

There are different types of mutations:

- Substitutions: the exchange of one base for another occurs (eg changes a C for an A), which could lead to a codon change that codes for a different amino acid causing changes in nascent protein, generating a codon that codes for the same amino acid without any change in nascent protein; generate a different codon for the amino acid: a stop codon and cause an incomplete protein to form.

-Insertions: base pairs are added to the DNA sequence.

-Deletions: base pairs are removed from the DNA sequence.

Among the products of glycolysis, which compounds contain energy that can be used by other biological reactions?a) ATP onlyb) py
Sunny_sXe [5.5K]

Answer: A (ATP only)

Explanation:

Both NADH and pyruvate are energy store. NADH and pyruvate can not directly be used to drive biological reaction.The metabolism of pyruvate releases energy in the form of ATP. NADH produces ATP through the electron transport chain (ETC). Adenosine Triphosphate (ATP) is referred to as the energy currency of the cell. ATP is used directly as energy to drive endergonic and exergonic biological reaction.

Answer is ATP only
