The oldest true fossils are trace fossils called Stromatolites found in Australia, and dated between 3.5 to 3.3 billion years old.

Raphael Baumgartner and their team have finally uncovered evidence of organic matter in the ancient rock formations known as stromatolites found at the Dresser Formation fossil site in the Pilbara region of Western Australia. They detail their findings in a new article published in the journal Geology.

With a variety of methods, including scanning electron microscopy, scanning transmission electron microscopy, energy dispersive X-ray spectroscopy, Raman spectroscopy, nano-scale secondary ion mass spectrometry, and stable carbon isotope analysis, the researchers examined the samples in thin slices.

According to the team's analyses, pyrite, a mineral with many tiny pores, makes up the majority of the stromatolites. Additionally, the pyrite contains nitrogen-bearing organic material and strands and filaments of organic material that closely resemble the remains of microbial biofilm colonies.

In colorectal cancer, some tumor suppressor genes are inactive. This is an important factor resulting in uncontrolled cell divis
tresset_1 [31]

Answer/Explanation:

(1) a mutation in the coding region, resulting in an inactive protein

To check to see if there is a mutation, you could extract the DNA from the cancer cells and then perform PCR to amplify the gene of interest. You could then perform sanger sequencing and compare the sequence to the normal gene to see if a mutation is present. To test the effect of the mutation, you would want to see if an active protein has been formed.

To see if a normal sized protein has been formed, you could perform a western blot, comparing the protein band to the WT protein band. If the protein is absent or much smaller, it is likely not a functional protein.

(2) epigenetic silencing at the promoter of the gene, resulting in reduced transcription.

To check for changes in the epigenetic landscape of the promoter, you could perform chromatin immunoprecipitation by extracting the chromatin from the tumour cells and using antibodies for different chromatin marks to see what has changed between the normal cells and the tumor cells. E.g. H3K9me3, H3K27me3. You would perform a pull down with the antibody of interest and then PCR for your promoter to specifically look at changes at that gene compared to normal cells. To test DNA methylation, you could perform bisulfite sequencing.

To see how transcription is affected, you could extract RNA from the tumor and normal cells, and compare the levels of RNA between the two samples by qRT-PCR

Yakvenalex [24]

As you did not state what the question is you just wrote a statement, I am guessing this is a True or False question. If there is more to the question please comment and Id be happy to help you answer more but if this is T/F then Ill answer it here right now.


A main-sequence star maintains a stable size as long as there is enough hydrogen to fuse into helium. True or False?

Answer:  True


Hope this Helps, good luck, and comment if you need help on anything else :)
