Question

In an mRNA molecule, a group of three nitrogenous bases makes up a codon, and each codon codes for an amino acid.

Answer 1

There are four different nitrogenous bases that can be arranged into different codons, but there are only 20 different amino acids. Based on this information, what conclusion can you make about the genetic code?

During translation, nitrogenous bases are rearranged into a sequence that corresponds to an amino acid.

Each codon can be translated into more than one possible amino acid.

Many of the possible combinations of nitrogenous bases do not code for anything and are not involved in gene expression.

Several different codons result in the production of the same amino acid.

Answer 2

one codon codes for only one amino acid. but a same amino acid can be coded by different codon, we call them as degenerate codon. this is well explained by wobble hypothesis. the third position the codon is occupied by unusual nitrogenous base and is responsible for degeneracy.

Answer 3

DNA is the genetic code for life. With it, proteins are coded. With proteins, large parts of our body are constructed (such as the alphabet). The process by which DNA turns into mRNA, and translation from the mRNA to amino acids is very intriguing, but also can be somewhat complex.

thanks, but which one would it be?
