A geneticist discovers that two different proteins are encoded by the same gene. One protein has 56 amino acids, and the other h
sergeinik [125]

Answer:

The same gene encodes both proteins by using different combinations of exons in the pre‑mRNA via alternative splicing.

Explanation:

According to the question, two different proteins (one with 56 amino acids and the other with 82 amino acids) are found to be encoded by the same gene. This is possible due to a process called ALTERNATIVE SPLICING.

Alternative splicing is a phenomenon whereby the protein-coding region of a gene called EXON is manipulated in such a way that variety of proteins emanate from a single gene. This manipulation includes the removal or inclusion of EXONS in the gene, so as to give rise to different combinations of mRNA, hence, different proteins will be translated from the different mRNA from the same gene.

In this case, exons were removed from one mRNA to have lesser amino acids (56) in the translated protein while exons were included in the other mRNA to have more amino acids (82).

Huntington disease is a dominant autosomic disease so it presents either in heterozygosity (Aa) or in homofzigosity (AA)

observing the pedigree, the two parents have the Aa genotype so by making the punnet's square we have as possible genotypes: AA, Aa, Aa, aa. So the chance to get the disease is 25%

How might water on the surface of the solid culture medium cause the disruption of colony formation?
lord [1]

Answer: There can be few reasons why surface on water can be harmful to the bacterial colony.

Explanation:

It is possible that while preparing the media for the bacterial colony that the constituents might not have been taken right proportion and water is more in it.

It tends to float on the surface and if the bacterial colony is not able to grow in such an environment it will led to the death of the colony.

There are chances that the mobility of the bacterial species increases in water and because of this there will be problems faced at the time of isolation.
