The corn we eat today is larger and has more kernels than the corn people first grew thousands of years ago. Which process is most likely responsible for the changes that have occurred?
mitosis
succession
direct harvesting
selective breeding
Selective breeding is a genetic engineering technique that creates organisms with
the same genes
desirable traits
50% of the same genes as the parent
25% of the same genes as the parent
What is genetic technology?
practices/techniques used to alter/manipulate the genetic material of an organism to produce a specific trait
practices/techniques used to determine the likelihood of contracting a particular disease
The following image shows
cloning, so the new plant is genetically different
cloning, so the new plant is genetically identical
selective breeding, so the new plant is genetically different
selective breeding, so the new plant is genetically identical
Which image depicts cloning?
Which image depicts gene splicing?
What occurs in gene splicing?
a specific gene is removed from the DNA of one organism and inserted into the DNA of another organism to produce a specific protein
the entire nucleus is removed from a cell and entered into an egg cell of a different organism to create genetically identical offpsring
How does gene splicing allow for mass production of insulin in laboratories?
The insulin gene is removed from human DNA and inserted into bacterial DNA, resulting in a combination of different DNA.
The human gene is removed from bacterial DNA and inserted into human DNA, resulting in a combination of same DNA.
The bacterial gene is removed from bacterial DNA and inserted into human DNA, resulting in a combination of different DNA.
