The human insulin gene contains a number of sequences that are removed in the processing of the primary rna transcript. in spite of the fact that bacterial cells cannot excise these sequences from primary rna transcripts, explain how a gene like this can be cloned into a bacterial cell and produce insulin.
a) bacterial cells can be easily modified so that they are able to excise introns.
b) plasmids containing an insulin gene that is derived from cdna, rather than genomic dna, would be void of introns. therefore, intron processing would not be necessary.
c) plasmids containing insulin genes derived from genomic dna would be void of introns. therefore, intron processing would not be necessary.
d) plasmids containing insulin genes derived from genomic dna would contain introns, but because the intron sequences are relatively short, the newly synthesized insulin would still likely be functional.

The idea that all living things are made up of cells is considered scientific law. this means the idea is an emerging scientific idea that has a logical explanation. has been tested with similar results at least twice. is supported by scientific consensus and a large amount of evidence. has been rejected only once by the scientific community

The basic types of tissue in the human body are

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
