The luster tells if a mineral is metallic or not.
<h2>
Correct Answer is (C)</h2>
Explanation:
(C) Use of reporter genes
- <em>Reporter gene</em> A quality that is utilized to<em> 'tag' </em>another quality or DNA succession of interest, for example, <em>an promoter</em>
- Expression of the correspondent is handily observed, and allows the function or whereabouts of the<em> 'target' sequence</em> to be tracked.It have a two type of reporter gene such as scorable reporter gene and selector gene
- Scorable reporter gene - The gene have expression of this result in quantifiable phenotype and easily detected through highly<em> sensitive enzymes assays </em>
- Selector gene- The gene expression<em> resistance to a toxin</em> and selection of tranformants from <em>non tranformants in growth media containing selective agents </em>
The answer is <span>B) three chromosomes in any one set.
In a human diploid somatic cell (2n), there are 22 chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes (so choice C. does not indicate a genetic problem). There are in total 46 chromosomes (23 pairs in 2 copies), that differs in lengths (so choice D. does not indicate a genetic problem). Speaking of a pair of sex chromosomes, there could be two X chromosomes in females or one X and one Y chromosome in males (so choice A. </span><span>does not indicate a genetic problem).
But, having three chromosomes in </span>any one set suggests a presence of trisomy, which is <span> a condition in which an extra copy
of some chromosome is present. This results in a genetic disorder.</span>
Answer:
a. In chlorophyll photosystems, the photons excite electrons that are transferred from donor to acceptor molecules in a process that involves oxidation-reduction reactions
b. As negative controls could be produced targeted mutations in genes encoding for enzymes that are not involved in the growth and in the photosynthetic activity
c. The plants that have many classes of photosynthetic pigments absorb light in different ranges of the visible spectrum, thereby it may confer an adaptive advantage to these plants
