What information can not be obtained from the sequence of a gene? view available hint(s) what information can not be obtained fr
olganol [36]

The right answer is A.

The methylation profile of DNA is not obtained when DNA sequencing is performed.

Methylation is a process that can occur in DNA especially at the cytosine level. And this has a very important role in gene expression as it is part of the epigenetic expression.

Gene methylation can induce or repress gene expression depending on the localization of methylated bases.

You cross purple-flowered and white-flowered pea plants, and all offspring are purple. how come? select one:
Vaselesa [24]
To solve this problem on genetic dominance, we will need a punnet square.

Let's let P represent purple-flowered and p represent white-flowered.

We have one purple flowered plant with the alleles PP, and we have one white flowered plant with the alleles pp. Using a punnet square, we can determine the alleles of the offspring.

       <u>P</u>     <u>P</u>
p|    Pp   Pp

p |   Pp   Pp

As we can tell from our punnet square, all of our offspring will have purple flowers. This is because the purple-flower allele is dominant and the white-flowered allele is recessive.

Since each flower has a dominant and recessive allele, they are heterozygous.

Therefore, the solution to this problem is D.
