Answer:
The correct answer is option D) "The enzyme will use any tRNA species but is highly specific for a given amino acid".
Explanation:
Aminoacyl-tRNA synthetases, also known az tRNA-ligase, are the enzymes that catalyze the attachment of the appropriate amino acid onto its tRNA. It is false to affirm that these enzymes will use any tRNA species but is highly specific for a given amino acid. In fact, aminoacyl-tRNA synthetases are highly specific for both, tRNA species and amino acids. Kinetic studies show that aminoacyl-tRNA synthetases reject wrong tRNAs during catalysis.

SEGMENTED BODIES
Annelids are your oligochaetes (earthworms), polychaetes (bristle worms), hirudenes (leeches) and some more. Their main characteristic is true segmentation
Answer:
I have identified <em>Escherichia coli </em>and<em> Bacillus sp.</em>
Explanation:
I obtained my sample from soil, in a park near my house. The common bacteria on soil are gram positive and gram negative.
I found rods, and some are gram positive and long. They others are gram negative and very small and short.
The color of the gram positive is a dark blue, almost purple, and they are big and abundant, they are almost in lines, so I think they are a species of <em>Bacillus.</em>
The gram negative bacteria are extremely small and they look hot pink. They are very probably enterobacteria, and the most common enterobacteria is <em>Escherichia coli</em>. They do not have a particular order of arrangement.
DNA collecting samples helping species recover often depend, which can reveal valuable information about details ranging from inbreeding and population history to natural selection.
To measure the genetic diversity of particular gene, scientist look at how many different versions of it are present in a population.Use of molecular marker for identification of endangered species offer promise of conservation biology.
Conservation genetics is the application of genetics to understanding the decreasing population and species extincts.By effective managing these ecosystem we can help preserve threatens and endangered. It helps in determine evolutionary context of endangered species and enables the development of better management and strategies for endangered species.
