Both seta and cheta or chaete means bristles. I think the term can be used interchangeably . Just check this link:- http://en.wikipedia.org/wiki/Polychaete It about polychaetes a class of annelid worms. These are extracts form the passage:- Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called *chaetae, which are made of chitin. Indeed, polychaetes are sometimes referred to as bristle worms. Bundles of bristles, called *setae, project from the parapodia. http://en.wikipedia.org/wiki/File:Polychaeta_anatomy_en.svg Thats a cross section the terms have been used interchangebly.

siniylev [52]

Answer:

The correct answer will be option-is read by ribosomes during the process of translation.

Explanation:

The DNA is a nucleic acid made up of nucleotides which serves as a genetic material of the cell. It stores the information required by the cell in the form of codons made up of nitrogenous bases. The DNA after transcription forms a messenger molecule called mRNA which is read by the ribosomes to code for specific amino acid which binds to form the proteins, the building block of the body.  

Since the mRNA is read by the ribosomes during translation and not DNA directly, therefore, the selected option is the correct answer.

please give me brainlist and follow

Explanation:

Independent assortment states that all alleles are inherited independently of other alleles. This helps diversity because it helps to further the randomization of traits. If traits were always inherited together, as a "package deal", there would naturally be less diversity than the situation that exists.
