You add polynucleotide phosphorylase to a solution of ATP, GTP, and UTP. How many artificial mRNA 3 nucleotide codons would be p

zavuch27 [327]

Answer:

The correct answer is option D, that is, 27.

Explanation:

27 three-nucleotide codons would be possible when polynucleotide phosphorylase is supplemented to a solution of GTP, ATP, and UTP. As there are three nucleotides available, that is, guanine, adenine, and uracil and each codon comprise three nucleotides, thus, there would be a probability of (3)^3 codons, that is, 27.

Which macromolecule is involved in how hemophilia is passed from parents to their children

Serga [27]

Answer:

chromosomes

Explanation:

chromosomes which consist of genes which consist of DNA can pass on traits from parent to child.

it basically works by depending on the gender of the child it can inherit certain traits from its parents

so say the hemophilia is an XX being from the mom and to get the mutation you would need the X that has the mutation and either an X or Y from the dad.

I dont know if hemophilia affects X or Y but that is how the mutation would be passed on.

In MendAliens, normal head top is dominant to Bart head top, in which the top of the head is jagged. Suppose a MendAlien homozyg

Dafna1 [17]

Answer:

The genotypes of the two parents: normal head shape (HH) and Bart head shape (hh)

The genotypes in the F1 generation= Hh

The phenotypes present in the F1 generation= All normal head shape

Explanation:

Let's assume that the allele "H" is responsible for the normal head shape while the allele "h" gives Bart head shape. According to the given information, both the parents are homozygous. The genotype of the parent with normal head shape would be "HH" while that of the one with Bart head shape would be "hh". Since the normal head shape is dominant, all the F1 hybrid progeny would exhibit "normal head shape".

Name two ways water travels from land to enter the ocean

Kitty [74]

Answer:

Seepage; runoff

Explanation:

In nature, water is constantly circling: from the water surfaces it evaporates, travels up in the atmosphere, there it condensates, forms clouds, and then again falls to the land and water surfaces. This cycle has been going on for thousands and thousands of years and is known as the water cycle.

Now, the real question is how does the water, fallen from the clouds, on the land, travel back to the oceans.

Soil consists of multiple layers, some are water permeable, and some are not. When water (rain) reaches the soil, through tiny pores in upper permeable layers it will travel downward, deeper and deeper. This process is called the seepage. Upon reaching the water-impermeable layers, it stops, becoming part of what is known the underground water. It will continue to flow on this layer until it finds its way back on the surface, usually in a form of a spring, which will find its way to a river, and river will take that water to a sea or an ocean.

However, if the soil is to saturated with water, especially during long rainy, stormy period, or in the spring, after the snow melts. This excess water will, because of the gravity, flow over the earth's surface, from higher (mountains) to lower (valley) areas, making its way to some valley river, which will take it further to a sea or an ocean.

Upon reaching the ocean, this land-water can again join the water cycle, again and again.
