Katen [24]

Answer:

The mentioned case is an illustration of the missense mutation. A missense mutation is a kind of nonsynonymous substitution, that is, it is a mutation in which a variation in a solitary nucleotide leads to the formation of a codon, which encrypts for a distinct kind of amino acid.  

When a missense mutation takes place within a DNA, a modification in one of the RNA codon sequences results at the time of transcription. This change in codon will ultimately result in the formation of a different amino acid, which gets presented within a protein at the time of translation. Like in the given case, a change in codon resulted in the substitution of the amino acid tyrosine with an amino acid cysteine.

Which is an example of a eukaryote? A) Euglena B) AIDS virus C) lactobacillus D) cyanobacteria
vova2212 [387]
 The answer is Euglena. Euglena is a genus of single-celled flagellate eukaryotes. It is a large genus of unicellular protists, which have both plant and animal characteristics. All are motile by means of a flagellum. Most have chloroplasts (alga and plant characteristic). Euglenids are believed to descend from an ancestor that took up green algae by secondary endosymbiosis.

Veseljchak [2.6K]
<span>Pressure waves originate within the inner ear at the oval window and travel through the perilymph in the scala vestibuli. Pressure waves in this structure cause deformation of the cochlear duct. The pressure waves then displace specific regions of the basilar membrane, relating to frequency. Hair cells in the cochlea of this region are distorted, initiating nerve signals in the cochlear branch of cn viii.</span>
