Sequence the steps to making recombinant DNA from 1 to 5. 20. The plasmid becomes part of a host cell's chromosome.
21. A DNA fragment is inserted into a plasmid.
22. The DNA fragment replicates during cell division.
23. The plasmid enters a host bacterial cell.
24. A host cell produces a protein that it would not have produced naturally.

A DNA fragment is inserted into a plasmid.

The DNA fragment replicates during cell division.

The plasmid enters a host bacterial cell.

The plasmid becomes part of a host cell's chromosome.

A host cell produces a protein that it would not have produced naturally.

Explanation:

Recombinant DNA is the DNA molecules formed invitro or lab condition with the help of a plasmid, bacterial cell as host and a desirable gene or DNA fragment by the technique of genetic engineering or recombination. This is also known as molecular cloning.

The correct order of steps in the DNA recombination process are as follows:

The desired DNA fragment is inserted into a vector or plasmid.

The DNA fragment replicates during cell division.

The plasmid enters a cell of host bacterial

The plasmid becomes part of a host cell's chromosome.

A host cell produces a protein that it would not have produced naturally.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
