Which of these is happening when translation takes place?
beks73 [17]


The answer is B

Before the process of translation occurs, mRNA which bears the blue print or coded information for the synthesis of a specific protein arrives from the nucleus and into the cytoplasm where there are ribosomes

mRNA then attaches itself to a ribosome. The ribosome is the site where the protein is formed. It is sometimes referred to as the "work bench" of the cell. Once mRNA is attached, tRNA comes and begins to read and translate the coded information on the mRNA. This is the translation stage of  protein synthesis.

Based on the translated information, tRNA then fetches amino acids  from the pool of free amino acids found in the cytoplasm and brings them to the ribosome where they are joined to form a chain thus creating a protein.

select the cell cycle impairments that you predict would lead to cancer. recall that cancer arises from unregulated, repeated ce
Vera_Pavlovna [14]

Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.

Genetic mutations can occur during the life of a cell due to outside factors such as:

  • The <u>food </u>we eat
  • The <u>environment </u>we expose the cell to
  • The <u>substances </u>that touch the cell (e.g skin cells)

That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of  <u>programmed cell death</u>.

<u>Programmed cell death </u>is what tells a cell when it should stop growing and dividing. This is a <u>regulatory function </u>designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The <u>accumulation </u>of these cells is referred to as cancer.
