Answer:

Diatoms

Explanation:

Diatoms are a photosynthetic eukaryotic phytoplankton that virtually found in all waterways, fresh waters and  oceans, and also in most soils on earth. Diatoms play a very important role in the global carbon cycle. Diatoms are single-celled algae that has a characteristics cell wall that is made up of transparent opaline silicia that are elegantly sculpted.

When diatoms die, their shell or skeleton that is composed of silica, do not decay, but settle at the bottom of oceans as sediments to form what is often referred to as diatomaceous earth. It is this diatomaceous earth deposit that is then converted to diatomite powder, which is used as pesticides against insects such as ants, cockroaches, bedbugs and some other pests.

Answer:

A protein-coding gene has an open reading frame (ORF) that make easier its identification

Explanation:

During translation, the messenger RNA (mRNA) is read by the ribosomes as triplets of nucleotides called codons in the open reading frame (ORF). An ORF can be defined as a gene fragment composed of codons which are translated into amino acids in a polypeptide chain. According to the genetic code, the information encoded by these codons will specify the sequence of amino acids in the protein, as well as the start codon and stop codons of the protein-coding genes. A start codon (AUG) is a site at which translation into protein begins, while stop codons (UAA, UAG, and UGA) mark the site at which translation ends. Moreover, non-coding RNAs (ncRNAs) don't have ORFs because they do not encode for proteins, and therefore their identification is more difficult.

Religiously, yes; nationally, no.

Explanation:

Not all religions and beliefs have St. Louis, so there would be a sort of feast day in the particular religion St. Louis is regarded a saint.
