Answer:
Genetic engineering is deliberate modification of genome to gain desired traits.
The main steps of genetic engineering:
Restriction enzymes are used to isolate the required gene leaving it with sticky ends. Sticky ends are a short section of unpaired bases A vector, which is usually a bacterial plasmid or a virus, is cut by the same restriction enzyme leaving it with corresponding sticky ends. The vector and the isolated gene are joined together by ligase enzyme. The vector inserts the gene into required cells. The genes are transferred to animal, plant or microorganism cells, during early development, which allows them to develop with the desired characteristics.
Connectedness is defined as, “the state of being joined or linked.” In handwriting, connectedness would be when somebody’s letters are linked together.
Answer: The capital letters and lowercase letters smoothly run together without lifting the pen.
Answer:
Five types of evidence for evolution are discussed in this section: ancient organism remains, fossil layers, similarities among organisms alive today, similarities in DNA, and similarities of embryos. Another important type of evidence that Darwin studied and that is still studied and used today is artificial selection, or breeding.
