NASA scientists recently announced the discovery of a bacteria that could grow on arsenic instead of phosphorus(A bacterium that can grow by using arsenic instead of phosphorus. (2011). Science). How could this occur chemically (describe how P is used in the cell and how arsenic could replace it). What are some of the criticisms of scientists to the paper/concept chemically?
Solution
generally the Life is mostly composed of the elements carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorus . Although these six elements make up nucleic acids, proteins, and lipids and thus the bulk of living matter, it is theoretically possible that some other elements in the periodic table could serve the same functions. Here, we describe a bacterium, strain GFAJ-1 of the Halomonadaceae, isolated from Mono Lake, California, that is able to substitute arsenic for phosphorus to sustain its growth. some data show evidence for arsenate in macromolecules that normally contain phosphate, most notably nucleic acids and proteins. Exchange of one of the major bio-elements may have profound evolutionary and geochemical importance.

Give several pieces of evidence that RNA preceded proteins and DNA in living things. Do your
answers to (1) mean that the first life was RNA-based, with RNA serving as both the catalyst and
the genetic material? Briefly discuss the strengths and weaknesses of this hypothesis. It is
believed that the machinery for photosynthesis evolved only once, in the cyanobacteria.
However, several unrelated groups of eukaryotes, such as green plants, diatoms, and euglenoids,
are able to photosynthesize. How can this be explained? Answer each question True or False
(T/F). If the answer is false, explain why. Eukaryotic cells are more similar to archaea for genes
involved in protein synthesis and DNA replication, but more similar to bacteria for genes
involved in metabolism. RNA has been found in meteorites, and was produced in the Miller-
Urey experiment, giving evidence supporting the \"RNA-first\" hypothesis of the origin of life.
The last universal common ancestor of all living things lived less than 2 billion years ago. The
first living things required oxygen (O_2). The^12C/^13C ratio is higher in living things than in
atmospheric CO_2. Which of the following is your closest relative? Your second closest? a) a
fungus; b) a dinoflagellate; c) a pine tree; d) a choanoflagellate; e) a ciliate; f) an archaean Why
are marine organisms relatively common in the fossil record, but mountain-dwelling species
relatively rare?
Solution
1. RNA preceded proteins and DNA. This is strongly supported by the RNA World Hypothesis
proposed independetly by Carl Woese, Francis Crick and Leslie Orgel in 1960s. It says that the
ribosomes which are vital for protein formation are made up of RNA and the protein
arrangement task during traslation is actually carried by RNA thus confirming that the early
forms used RNA for their chemical reactions preceeding the use of proteins. Since RNA was
instable, eventually organisms started to depend on proteins and DNA for their activities.
2. The RNA theory states that the RNA was the earliest genetic material for the early forms of
life. This is due to the fact that RNA can act both as a genetic material and also as a catalyst
(enzyme). Because to carry out life processes the genes need to be produced. And this production
is dependent on enzymes inturn. A strong point that James Watson said is that RNA can translate
into DNA in the reverse transcription process, while doing so RNA itself could have acted as an
enzyme besides acting as a template to facilitate the reaction to carryout. This supports the
phrase \'Life requires autocatalysis\'. The weaknesses of this hypothesis are it is highly
unpredictable to have RNA nucleotides with the requirement of any enzyme. Which means RNA
precursors cannot be formed without an enzyme. This conveys the message that there could have
been another simple molecule which has the catalytic property and information storge system
other than RNA.

In order to understand the problem outlined in the scenario, it is helpful to place it in the
context of real research based on primary literature. This is what you need to do to make a
really effective lab report. Although the scenario is fictional, the science behind it is real and
should be used in the Introduction, Methods, and Discussion sections of your lab report. In
this section, you are provided with simple summaries of the major points of a number of
experimental and review papers (so you do not have to read them unless you wan to). You
are required to incorporate information from at least two primary sources into your lab
report in a sensible way. Do not forget to use in text citations and make a bibliography. The
paper you were provided for the Source Summary is the first primary source you should use;
for the second (and others) you can refer to this annotated bibliography rather than reading
papers yourself.
REMEMBER: Do not plagiarize this annotated bibliography or any other source! You
should write your report in YOUR OWN WORDS, and then refer to these or other sources in
support of what you are saying. These summaries were written by Dr. Keller, so you need to
paraphrase and incorporate any information into your own writing.

EXPLORING PHOSPHATE-SOLUBILIZING ASPERGILLUS SP: ISOLATION AND OPTIMIZATION O...indexPub
Background: The global phosphorus crisis is an evolving concern as the world's phosphorus sources are running out and demand for agricultural production is rising. Phosphorus shortages undermine food security and demand long-term management practices to assure phosphorus availability. Methods: Aspergillus strains were first screened on PVK media to get phosphorus solubilizing species and then the best strain was used to produce acid phosphatases. Finally, the effect of various assay conditions was analyzed to characterize extracellular acid phosphatases. Results: Out of four isolated strains, only A. niger, A. oryzae, and A. flavus were able to solubilize phosphate on PVK, of which A. niger stood out with a maximum solubility index of 2.38. The optimal pH and temperature for enzyme activity were recorded as 4.5 and 30°C. Furthermore, the substrate concentration of 100 mM with a 40-minute incubation period was found as a standard condition to achieve maximum specific activity i.e. 12 U/mg and a 17% higher free phosphorus level. After optimization, a 43.8% increment in the activity of extracellular acid phosphatases was observed. Conclusion: The study concludes that A. niger was the prominent performer, with improved phosphate solubilization and enzyme activity, as well as higher phosphorus release, demonstrating its potential for enhancing phosphorus availability not only in agricultural and environmental fields but in setups with lower phosphate availability too.

Solution
generally the Life is mostly composed of the elements carbon, hydrogen, nitrogen, oxygen,
sulfur, and phosphorus . Although these six elements make up nucleic acids, proteins, and lipids
and thus the bulk of living matter, it is theoretically possible that some other elements in the
periodic table could serve the same functions. Here, we describe a bacterium, strain GFAJ-1 of
the Halomonadaceae, isolated from Mono Lake, California, that is able to substitute arsenic for
phosphorus to sustain its growth. some data show evidence for arsenate in macromolecules that
normally contain phosphate, most notably nucleic acids and proteins. Exchange of one of the
major bio-elements may have profound evolutionary and geochemical importance.
