Answer:
these statements are true
B) Insertions or deletions of single base-pairs within a protein coding sequence probably change the amino acid sequence
D) Missense mutations always change the amino acid sequence encoded by a gene
E) Nucleotide substitutions outside of the coding sequence can affect the expression of a gene.
Explanation:
B) insertion or deletion of nucleotide in coding region of DNA can change the amino acid sequence encoded.
D) missense mutation means that the change in nucleotide sequence resulting in change in amino acid sequence encoded by gene.
E) A mutation may alter the promoter of a gene, thereby affecting the rate of transcription.
Answer:
They live in or around freshwater ponds, lakes, rivers, marshes and swamps.
Explanation:
Urbach-Wiethe disease is a rare genetic disorder that can cause calcification of brain tissue in the temporal lobes; this calcification can cause damage to the amygdalae.
<h3>What are the symptoms of Urbach-Wiethe disease?</h3>
The symptoms of the disease vary greatly from individual to individual.
They may include a hoarse voice, lesions and scarring on the skin, easily damaged skin with poor wound healing, dry, wrinkly skin, and beading of the papules around the eyelids.
<h3>What part of the brain does Urbach-Wiethe disease affect?</h3>
(1994, 1995) investigated a patient suffering from Urbach–Wiethe (UW) syndrome, a very rare autosomal recessive disease, which produces bilateral calcifications in the anterior medial temporal lobes, especially of the amygdalae, in 50–75% of cases (Newton et al., 1971; Staut and Naidich, 1998).
