Shtirlitz [24]

Answer:

The light bulb will have the same mass on the moon as it will on earth. The mass of an object will not change if the gravitational pull on the object changes, but the weight of the object will. For instance, if you measure your mass on Earth and then measure your mass on the moon, your mass will remain the same. The same theory applies to any object with mass.

hope it helps brainliest pls!! :)

Recombinant DNA uses what medium to produce new genes?
mestny [16]

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.
