In which step of protein synthesis does the rRNA make protein?
Inessa [10]

Answer:

Translation is the second part of the central dogma of molecular biology: RNA → Protein. It is the process in which the genetic code in mRNA is read to make a protein. Translation is illustrated in the diagram below. After mRNA leaves the nucleus, it moves to a ribosome, which consists of rRNA and proteins.

Explanation:

Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.

Is infant circumcision ethically necessary?
Nostrana [21]
The answer is that infant circumcision is not ethically necessary. The reason to this is that there are no proof of evidence as to why it is ethically necessary for it to be done to an infant. It is also because other medical professionals thinks that doing circumcision in an infant will create issues in terms of their health, producing complications. That is why it is not ethically necessary for it to be done on an infant.
