In standard cloning protocols, the cloning of any DNA fragment essentially involves seven steps: (1) Choice of host organism and cloning vector, (2) Preparation of vector DNA, (3) Preparation of DNA to be cloned, (4) Creation of recombinant DNA, (5) Introduction of recombinant DNA into the host organism, (6) Selection

Answer:

Explanation:

Processes of recombinant DNA technology involve isolation of DNA of the desired DNA fragment. In order to cut the DNA with restriction enzymes, it needs to be in pure form, free from other macromolecules. The DNA is enclosed within the membranes, we have to break the cell open to release DNA along with other macromolecules such as RNA, proteins, polysaccharides, and also lipids. This can be achieved by treating the bacterial cells/plant or animal tissue with enzymes such as lysozyme (bacteria), cellulase (plant cells), chitinase (fungus). The RNA can be removed by treatment with ribonuclease whereas proteins can be removed by treatment with protease.

A hypothesis that is scientific must have a test for proving it is called

Jlenok [28]

The question is incomplete. The complete question is as follows:

A hypothesis that is scientific must have a test for proving it wrong is called__________

Answer: scientific theory

Explanation:

A scientific theory can be defined as the experimental explaination of all the aspects of the natural world which is tested regularly and verified according to the scientific methods that uses many protocols of measurement,observation, and result evaluation.

A scientific hypothesis is always tested for validation and tried to prove wrong for better results and all the tests are performed under controlled conditions.

Hence, the scientific hypothesis always has a test called scientific theory.

_______ is located in the anterior neck produces key hormones for metabolism

Lapatulllka [165]

Answer:

THYROID GLAND

Explanation:

Thyroid gland functions in metabolisms by activities of thyroid cells.This cells withdraws Iodine from metabolites and combine it with amino acid tyrosine for productions of Thyroid hormones:

ThyroxineT3,(20%)

TriiodothyronineT4(80%). This production is under the influence of Thyroid stimulating hormones,regulated by the pituitary gland,

T3 and T4 increase calorinogenesis, (liberation of heat from digestion to supply energy,and oxygen consumption of the heart.)

Deficiency of thyroid hormones are goiters, hypothyroidism, and hyperthyroidism

An experiment that

gayaneshka [121]

Answer:

fails to verify

Explanation:

An experiment that fails to verify a hypothesis will often provide a new direction for the researcher.

Researchers conduct experiments to develop hypotheses. A hypothesis is a testable and falsifiable explanation. A hypothesis can be tested. It is possible to prove the hypothesis as true or false.

An experiment is a way to test the hypothesis.

The process of producing recombinant dna involves taking a gene from one organism and attaching it to the dna from another organ

Lorico [155]

An American drug enterprise has devised a manner of producing insulin by way of recombinant DNA technologies. Insulin encompass 2 polypeptide chains (A and B) appropriate by way of disulphide bridges. The polypeptides are 'engineered' one after the other, and later further collectively to make lively insulin. The bacterium used is a stress of E. col
 It would be like taking a gold ring, breaking it open, and saudering to it a silver ring.
