ikadub [295]

The type of mutation that occurred here is an inversion of three nucleotide bases (Option A).

<h3>What is an inversion?</h3>

An inversion is a type of mutation where linear order of nucleotide in the mutated sequence is inverted.

In this case, we have an inversion that involves the following bases (bold highlighted) AATCGC TAC GCACGTCAG and AATCGC CAT GCACGTCAG.

In conclusion, this mutation is an inversion of the genomic sequence (Option A).

Why is the concept of using the information in DNA to make proteins considered the central dogma of biology
serg [7]

Answer:

"The central dogma of molecular biology explains the flow of genetic information, from DNA to RNA, to make a functional product, a protein. The central dogma suggests that DNA contains the information needed to make all of our proteins, and that RNA is a messenger that carries this information to the ribosomes."

Lena [83]

Answer:

No, observed and expected frequencies are different.

Observed frequencies: p2 = 0.56 , 2pq = 0.375, q2 = 0.062

Expected frequencies: p2 = 0.774 , 2pq = 0.211, q2 = 0.014

Explanation:

Given frequency of recessive genotype (q2)= 14/ 1006 = 0.0139

Frequency of recessive allele s (q) = square root of 0.0139 = 0.12

Frequency of dominant allele S (p) = 1-q = 1-0.12 = 0.88

Expected frequency of homozygous recessive genotype = 0.12 x 0.12 = 0.014

Expected frequency of homozygous dominant genotype = 0.88 x 0.88 = 0.774

Expected frequency of heterozygous dominant genotype = 2pq = 2 x 0.88 x 0.12 = 0.211

Observed frequencies in population 2

Observed frequency of homozygous dominant genotype = 308 / 549 =0.56

Observed frequency of heterozygous dominant genotype = 206 / 549 =0.375

Observed frequency of homozygous recessive genotype = 34 / 549 =0.062

Observed frequencies do not match with expected frequencies.

The influx of Na+ from the scala vestibuli is critical in mechanotransduction to occur in the vestibular system.
sergij07 [2.7K]

Answer:

True

Explanation:

The scala vestibuli contain perilymph in which there is a domination of Na+ ion which is K+ in endolymph. endolymph has domination of K+ because they have very large potential as compared to perilymph this is also called endocochlear potential . there is a potential difference of about 150 mV across the stereocillary membranes that drive cations through mechanotransduction channels
