Perhaps the most significant molecules in cell biology are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), which store and read the genetic information that is the basis of all life. Both are linear polymers made up of sugars, phosphates, and bases, but they differ in a few significant ways.
These differences allow the two molecules to cooperate and perform their fundamental functions. Here, we examine 5 significant distinctions between DNA and RNA. All genetic information is encoded in DNA, which also serves as the building block for all biological life.
And only in the near future. In the long run, DNA serves as a storage medium, a biological flash drive that enables the transmission of the genetic code from one generation to the next.

Suppose that goats have one gene that codes for color, where A is brown and a is white. The goats also have another gene that codes for height, where B is tall and b is short. If these two genes are unlinked, what is the probability that a cross between Aa Bb × Aa bb parents will produce three out of five offspring that are brown and short? Enter your answer as a decimal, rather than as a percentage.
probability:
The probability that 3 out of 5 offspring from the cross will be brown and short does not exist or is zero.
Dihybrid crossingA represents brown and a represents white.
B is tall while b is short.
AaBb x Aabb
Offspring
A_B_ (brown and tall) = 6/16 or 3/8
A_bb (brown and short) = 6/16 or 3/8
aaB_ (white and tall) = 2/16 or 1/8
aabb (white and short) = 2/16 or 1/8
In other words, the probability of producing offspring that are brown and short is 3/8.
Thus, the probability that 3 out of 5 offspring from the cross will be brown and short does not exist or is zero.

Examine the data shown in Figures 2 and 3. Carefully compare the DNA methylation profiles from the 3-year-old twins versus the 50-year-old twins and summarize your observations. Which set of twins (3-year-old or 50-year-old) have the most similar DNA methylation profiles? Provide a brief explanation of your observations.
A DNA base is altered biochemically during DNA methylation, which typically takes place during gametogenesis and after fertilization.
The DNA methyltransferases DNMT1, DNMT3A, and DNMT3B keep methylation marks in tact after each cell division. Although the majority of methylation marks are stable, there is typically 10% to 20% variation over time. Ly cytosine undergoes enzymatic 5-carbon methylation. DNA methylation represents the best characterized form of epigenetic modification. DNA methylation is written onto the genome by two methyltransferases, known as Dnmt3a and Dnmt3b.These enzymes catalyze the addition . Aging is often marked by the establishment of global hypomethylation and regions of CpG island hypermethylation. These changes in the epigenetic landscape may contribute to aging by adversely affecting genomic stability and gene regulation. Thus, DNA methylation has its affect on aging and thus should be observed carefully.Learn more about DNA here:

A cinder cone volcano easily erodes because it is made of ash and other volcanic debris. This indicates that its eruption is primarily _____.
A) explosive with a pyroclastic flow B) non-explosive with a pyroclastic flow C) explosive with pyroclastic and lava flows D) non-explosive with a lava flow
PLEASE HELP GIVING BRAINLIEST TO FIRST CORRECT ANSWER
A cinder cone volcano easily erodes because it is made of ash and other volcanic debris. This indicates that its eruption is primarily explosive with a pyroclastic flow.
Volcanoes with cinder cones are the most basic. They are made of lava chunks and blobs that were ejected from a single vent.
A single vent is surrounded by a conical formation of ash, tephra, and solidified lava called a cinder cone. After being ejected into the air from the vent, volcanic debris breaks apart and falls to the ground, forming the cone. As the ash and lava cool and solidify, they form a cone around the vent.
The height of a cinder cone can range from 10 to hundreds of meters, and its summit frequently features a bowl-shaped crater. They differ from spatter cones, which are made of agglomerated volcanic bombs, in that they are made of loose pyroclastic material (cinder or scoria) and hence eruption is primarily explosive with a pyroclastic flow.

1. What is the change in volume from 22 degrees Celsius to 23 degrees Celsius?
Answer:
According to Charles' Law.
Volume is directly proportional to Temperature.
So if temperature increases from 22degree Celsius to 23degree Celsius, then Volume will increase from its initial.
The change in volume from 22 degrees Celsius to 23 degrees Celsius is seen because the change in temperature is directly proportional to the change in volume and the volume increases.
What is the role of temperature?The role of temperature is important as the low temperature changes the state that is from the liquid to the solid while the high temperature changes the state of matter that is from the liquid to the gas. The temperature of the earth is continuously increasing, so that the polar ice is melting and the water level on the earth is increasing. The increase of one degree is significant in the earth as the ice melts into the water, and that harms the animals and plants present in the different habitats.
Hence, the change in volume from 22 degrees Celsius to 23 degrees Celsius is seen because the change in temperature is directly proportional to the change in volume and the volume increases.

1. What happens when the vertical angulation is steep (+70°)? Is the shadow shorter or longer?
2. What happens when the vertical angulation is flat (+20°)? Is the shadow shorter or longer?
How does this relate to distortion?
The correct answers are shorter, longer, and have inverse proportionality and are used in dental radiography.
In the first case vertical angulation is what is used to control the length of any image which is being recorded and it is dictated by the holding device which directs the beam of x-ray perpendicular to both the receptor and teeth and in this case the image which is formed is shorter then the real teeth and it also occurs if the central ray is directed perpendicular to the plane of the receptor rather than to the imaginary bisector.
In the second case, the vertical angulation is flat or if it is too small the image of the teeth will be longer than the actual teeth and it often occurs due to bisecting technique.
Distortion is any kind of change that can occur in both the shape and size of the object and this is inversely proportional to the vertical angulation as when vertical angulation is not correct it creates distortion and also the steep is angulation the smaller the image will be and flat the angulation is the larger or longer the image is and in distortion which comes due to radiograph is mainly used for the teeth and the recommended angulation is +10 degree in which the central ray is directed through the contact of the teeth.
This is also called dental radiography.
