A codon is a sequence of three bases found on the messenger RNA (mRNA) molecule which is translated to produce an amino acid. Each amino acid is coded by one or more specific codons. If the codon is changed through a mutation, the amino acid produced may be different. However, in this case, the other codons that produce Leucine are:
UUA, UUG, CUU, CUC, CUA and CUG
So the code CUU could mutate to CUC, CUA or CUG and leucine would still be produced.

Answer:
Coordinates biofilm formation via chemical signaling among cells. (Ans B)
Explanation:
Quorum sensing in bacteria uses to regulate certain expressions such as phenotype which in turn, coordinate their behavior. Some common phenotype examples are biofilm formation, motility, and virulence factor expression.
Some bacteria have the ability to use quorum sensing to regulate nitrogen fixation, bioluminescence, and sporulation. Quorum sensing regulates genes involved in biofilm development, it helps to promote biofilm dispersion and upregulates the synthesis of surfactant molecules. Quorum sensing and biofilm development are known as social bacterial behaviors.
Answer:
The correct answer is - smooth muscles.
Explanation:
inside the organs, there are internal muscles present that build walls of most of the organs like the stomach, heart, blood vessels, intestines, and more hollow organs. These muscles are composed of ininvoluntary muscles.
These muscles can not be controlled as these are meant to be working on their own with the stimulus. The role of such muscles is to push or pull the various material such as blood, or food through the organs.
Thus, the correct answer is - smooth.
