Deffense [45]

The manipulation of genes for practical purposes, such as medicine, agriculture, or criminal justice, is called GENETIC ENGINEERING. These technologies involve the manipulation of the DNA molecule.

Deoxyribonucleic acid (DNA) is the molecule that carries the instructions (i.e., genes) for all organisms to develop, survive, grow and reproduce.

Genetic engineering techniques consist of the manipulation of the DNA molecule in order to produce desirable phenotypic features in the offspring of an organism.

Genetic engineering techniques use recombinant DNA strategies to modify the genetic makeup (DNA) of the target organism.

LuckyWell [14K]

Answer:

B. an amino terminal signal peptide

Explanation:

The reactions of the citric acid cycle occur in the matrix of mitochondria. Therefore, all the enzymes required for this pathway are present in the matrix of mitochondria. These enzymes are formed on the ribosomes present in the cytosol and are transported into the mitochondria with the help of cytosolic heat shock proteins. The newly formed mitochondrial proteins have signal sequences present at their N terminal. The proteins to be transported into the matrix have a single signal sequence that at N terminal which is removed by a protease once the enzyme enters into the matrix.

Andru [333]

Answer:

Stage IV - There is a primary tumor, lymph node involvement and metastases.

Explanation:

Staging is the extent of spread of tumor within the patient.

The American Joint Committee on Cancer (AJCC) divides all cancers into Stages 0 - IV, incorporating into each stage several TNM (tumor/node/metastasis) stages usually with the same prognosis.  

Staging is essential in determining the patient prognosis.

The approximate 5-year survival rate for colorectal cancer patients of all stages is 64.4% (In the United States) and survival is inversely related to stage.

Surgery usually provides the only curative option for patients diagnosed with Stage IV colon cancer.
