MacConkey agar is a selective and differential culture medium for bacteria designed for isolation of Gram negative and usually enteric bacilli, based on their ability to ferment lactose. It contains bile salts, crystal violet, neutral red dye. There are many variations of MacConkey agar depending on the need. This medium was developed by Alfred Theodore MacConkey. This agar can distinguish gram negative bacterias that can ferment. This is known as the indicator medium.
Answer:
A peptide bond must form between subunits of mRNA
Explanation:
Translation occur in the RIBOSOMES and it is the process where protein is produced by reading the genetic code of messenger RNA.
For translation to occur,A peptide bond must form between subunits of mRNA because it is through the formation of peptide bond between subunits of mRNA that the small ribosomal subunit binds to the start of the mRNA sequence. Then a transfer RNA molecule that carry Amino acids methionine binds to the start codon of the mRNA .The start codon in all mRNA molecules has the sequence AUG and codes for methionine.
All life is based on the chemical element cabon. It is essential to life.
