Which of the following cellular structures reads the sequence of codons in mRNA and uses them to build a protein.(BRAINLIEST)
podryga [215]

Answer: The correct answer is- C) Ribosome.

Ribosome is a specialized cellular machinery ( made up of ribosomal RNA and proteins), which is present in both prokaryotic and eukaryotic cells.

It acts as a site for the process of protein synthesis as it reads the codon sequence ( a sequence of three nucleotide in mRNA that codes for an amino acid) present in mRNA ( messenger RNA) and utilizes it in the process called translation ( formation of protein from mRNA).

As per the specific codon sequence of the mRNA, it links the corresponding amino acids together, which results in the formation of specific protein ( polypeptide).

Thus, option C) is the right answer.

Who is Gregor johann Mendel?
qaws [65]
I’ll give you a short overview of what I know.

He was a scientist, biologist, and wrote many books. He was specifically known for creating the science of genetics.

Mendel was born in 1822 into a poor farming family and then died January of 1884. He was an Austrian monk who discovered the basic principles of hereditary through experiments in his very own garden!

I’m sorry. I don’t believe this defines him. You can’t really define anyone in this short of a paragraph. To really know him, I’d have to do deeper research.
As for now, I hope this helps out. This probably just scratches the surface of who he really was. Have a great night!

All my best,
~Brooke❤️
