Answer:
The answer to your question is: Active transportation
Explanation:
Cell can move molecules in or out of it by two processes: Active or Passive transport.
Active transport: is the movement of molecules against a concentration gradient. Use proteins or enzymes to happen.
Passive transport: is the movement of molecules or ions from a higher concentration to a lower concentration.
The genetic characteristic of two different organisms are induced into a new host organism for the purpose of producing new genes.
<u>Explanation:</u>
In the field of bio technology, Recombinant DNA technology plays a very important role. This helps in the production of genes. The first thing insulin of human was produced with this technology. In this technology, the gene that is to be produced is cut and it is placed inside a host organism where it gets multiplied.
This technology uses five steps in gene production. Firstly, the DNA that is essential will be cut. this is done by restriction site. PCR is used secondly in order to amplify the copies of the genes. Then these are induced into Vectors after which they will again be introduced into a host organism. Then finally the results will be the genes of the desired characteristics.
The correct answer of the given question above would be the r<span>egulation of the cell cycle at internal checkpoints. The regulation of the cell cycle at internal checkpoints is the criteria that you can use to assess the developmental potential of a cell. </span>
The strands of DNA are wrapped around histone proteins. The packaging is advanced further to the secondary and tertiary structure packaging level. In the end, the entire structure is completely packed in the form of a chromosome to fit within the nucleus of a single cell.
I believe the answer is A. Lipids function as cushioning. Hopefully this helps.
