Chromosome is to cactus as gene is to needle.
To identify the host cell that has taken up the gene of interest
Answer:
proteins; purify; expression
Explanation:
One of the products of recombinant DNA technology is antibiotics. To have penicillin, we used to have to breed fungus that produces the drugs. With recombinant DNA technology, you can extract the DNA that needed to produce penicillin, then put it into a bacteria using an expression vector. This technology will allow us to produce a specific protein (whether its enzyme, hormone, or anything) easier.
Answer:
Explanation:
Terrestrial plants have stomata on the surface of their leaves. A single stomata is surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma.

Answer:
DNA restriction enzymes cut the DNA molecule, while DNA ligases join the resulting DNA fragments
Explanation:
Transformation is a naturally occurring process by which bacteria incorporate exogenous genetic material from their surrounding environment. This process (transformation) is used for DNA cloning via plasmid vectors. In DNA cloning, transformation occurs after restriction enzymes cut the DNA at specific sequences named palindromic sequences (i.e, sequences that can be read the same in opposite direction). Restriction enzymes can generate sticky-ends, where enzymes make staggered cuts in the two strands (e.g., <em>BamH</em>), or blunt ends, where the resulting strands are of the same length (e.g., <em>HaeIII</em>). In general, sticky-end enzymes are more useful because they generate a 3' overhang in one molecule and a complementary 5' overhang in the other, increasing the yield and specificity of ligation. During ligation, a DNA ligase is used to join both DNA strands by forming phosphodiester bonds in the plasmid. Following transformation, bacteria can be selected on antibiotic plates.
