Answer:

Tastes are detected on the tongue through cells called gustatory cells. Gustatory cells have a variety of taste receptors. When bitterness is detected, the brain receives a message from these cells.

The taste of PTC is associated with a gene formed by the alleles responsible for tasting and non-tasting. These alleles are extremely important for us to be able to feel the different types of flavors.

The allele that codes for taste, is present in the taste buds of the tongue and can react with PTC molecules, allowing us to feel a characteristic bitter taste for that molecule. On the other hand, the non-gustatory allele is unable to react with PTC molecules. When these two alleles are combined within a genotype, the individual has a phenotype that allows sensitivity to the presence of the PTC flavor.

What is the amino acid sequence for the mRNA strand CACCCAUGGUGA?
krek1111 [17]

Answer:

Histidine- Proline- Tryptophan- Stop codon

Explanation:

The mRNA strand in the question is produced as a result of a process called TRANSCRIPTION. However, the mRNA transcript is further used to synthesize an amino acid sequence in a process called TRANSLATION. The mRNA sequence is read in a group of three nucleotide bases called CODON.

Each codon specifies an amino acid which is represented in the GENETIC CODE. In this case, a sequence of mRNA strand is given as: CACCCAUGGUGA

The following codons in the sequence specify the following amino acid:

CAC - Histidine

CCA - Proline

UGG - Tryptophan

UGA - Stop codon

Hence, the amino acid sequence encoded by the given mRNA strand is Histidine- Proline- Tryptophan- Stop codon.

N.B: After a stop codon (UGA, UAA, UAG) is encountered, the translation process stops.
