Make connections Imagine you want to study one of the human crystallins, proteins present in the lens of the eye (see Figure 1.8
Lelechka [254]

Answer:

In order to clone the sequence of the gene for one of the human crystallins found in the eye, there is a need for the application of polymerase chain reaction. In the process, the particular sequence of gene is denatured and then replicated various times to generate various clones of the gene sequence.  

By producing various copies of the gene sequence for the human crystallin, that is, desirable, a scientist can examine various distinct characteristics of the protein as there is always more to examine with.

Determine whether each of the following is a characteristic of the life cycle of a seed plant, a seedless plant, or both. Double
Gnoma [55]

Double fertilization-plants with seeds (flowering plants), two male gametes joining with female gametophyte

Gametophyte generation-both (haploid, sexual stage stage-gametophyte, and the diploid stage that produces spores – sporophyte)

Endosperm formed-plants with seed because it is a tissue formed inside the seed which surrounds the embryo and provides nutrition

Mitosis-both (mitosis occurres in spores)

Spores develop into gametophytes-both but, in seedless plants sporophyte produces spores that will develop into a new organism (multicellular gametophyte) using mitosis, while spores of seed plants are produced internally and develop into more complex structures.
