Simple version:
First, the section with the desirable gene must be identified. Assuming that has already happened, the section of DNA must be excised from the original genome using restriction enzymes, which recognize certain DNA sequences and snip DNA at those sites. DNA ligase is used to "glue" these ends back together. The DNA is inserted into a plasmid (also with restriction enzymes), which would usually contain antibiotic-resistance genes (so they survive in an environment containing the antibiotic, which would also help show if the bacteria have been successfully transformed).
Then comes the actual transformation process. The bacteria to be transformed are mixed with calcium chloride (which causes the bacteria to be more receptive to the plasmids) and then mixed with the plasmids. The bacterial cells are subjected to a heat shock (the solution is heated and rapidly cooled, e.g. by placing the mixture in a hot water bath and quickly transferred to ice) so they will take up the plasmid (since the temperature change makes the membrane more permeable). The bacteria are placed on a growth medium containing the antibiotic they're resistant to. Only those successfully transformed would survive.
Sugar and starch are Carbohydrates.
Answer: Option B.
Breast milk lack Vitamin D.
Explanation:
Breast milk is the liquid substance given to infants by the mother which is secreted by the mammary gland or breast.
Breast milk contain a lot of nutrients needed for growth and development of infants. Breast milk contains proteins( human milk contain two types of protein, whey and caesin) carbohydrates, fats, minerals and vitamins except vitamin D, the bady will need additional source of vitamin D. Breast milk make the baby healthy, it prevent sickness and allegies, it supply the necessary nutrients the baby needs.
One gene for a particular trait is transcribed from DNA during transcription. The code for the gene is transferred by mRNA to the ribosome for protein production to begin. Proteins are constructed from a polypeptide chain of amino acids
