You have recently discovered a new gene, have it cloned, and suspect this gene is a proto-oncogene. What is a proto-oncogene and

how would you test your hypothesis that your gene fits this description?
Biology
1 answer:
likoan [24]3 years ago
4 0

Explanation:

A proto-oncogene is a<em> normal gene that usually can stimulate growth and differentiation but if it mutates can become an oncogene and cause cancer</em>. In order to test this gene, you can <em>activate it by promoting its mutation with a DNA amplification (like the one you did in the question) or a chromosomal translocation,</em> then you can observe it in a culture <em>if there's cell transformation you can confirm your hypothesis.</em>

I hope you find this information useful and interesting! Good luck!

A wave with a height of a 5 feet and a wavelength of 15 feet has a wave base of
Tpy6a [65]
When a wave has a height of 5 feet and a wavelength of 15 feet then it has a wave base of 7.5 feet. Wave base is equal to the half of the wavelength so if you consider your wavelength to be 15 feet then it is divided into 2 that would give you answer of 7.5 feet.

The inheritance of gene expression patterns, in the absence of the initiating signal, is called what
Veronika [31]

The inheritance of gene expression patterns, in the absence of the initiating signal, is called Epigenetic regulation.

Epigenetic changes can be defined as inherited variations which are not present in the DNA sequence. Gene expression is regulated at different levels and not merely in response to DNA modifications. Examples of epigenetic control include DNA methylation, histone deacetylation and mi-RNA expression.

Epigenetic mechanisms add an adaptive layer of control in the regulation of gene expression that allows an organism to adapt to a dynamic environment.

Epigenetic regulation increases the functional intricacy of deoxyribonucleic acid (DNA) by changing chromatin structure, nuclear organization as well as transcript stability.

How closely do Mendel insights into dominant and recessives traits match up with the ratios that punnett calculated in his Punne
elena-14-01-66 [18.8K]

Answer:

Perfectly in theory, except there is chance involved

Explanation:

The Punnet square is a diagram that allows scientists to predict the possible outcomes of the offspring when the genotypes of the parents are known. This is in line with Mendel's principles, and from a theoretical point of view would match up perfectly. However, it all works based on <em>probability</em>.

However, inheritance is always down to chance. Of your parents 2 alleles, you always have 50:50 chance of inheriting one of the allele. Overall, this is what is predicted in punnet squares.

However, think about flipping a coin. There is always 50:50 chance of getting heads, but that doesn't mean it is impossible to flip a coin and get tails 10 x in a row. It is just less likely. So in reality, observations might deviate from the theory.
