Why must cytosine bind to guanine, while thymine bonds to adenine?

a
These are Chargaff's rules.
b
Like bonds with like.
c
Two-ring molecules (adenine and guanine) must bind with one-ring molecules (thymine and guanine) to keep the distance between DNA chains consistent.
d
This will not happen, as it violates Chargaff's rules.

Answers

Answer 1

These are Chargaff's rules that is why cytosine bind to guanine, while thymine bonds to adenine. Thus, the correct option is A.

What is Chargaff's rule?

According to the rule, in DNA there is always equality in quantity between the bases A and T and between the bases G and C. (A is adenine, T is thymine, G is guanine, and C is cytosine).

According to Chargaff's rule, Concentration of adenine = concentration of thymine. therefore if [A]=40% then the [T] will also be 40%.

if destructive interference occurs between a wave with a six foot trough and a three foot crest, what factors will determine the height of the resulting wave?

Answers

Destructive interference formed when the two meeting waves are out of phase and in some cases, the two wavers maxima are 180 degrees out of phase. The height of waves is determined by the wind speed, how  the long wind blows, and crucially the fetch.

The longer the duration of wave, the larger will be  the wave heights. The longer the fetch, the large will be wave heights.

What is interference?

Some waves jump to cross over or meet with each other. When they do, the reaction between the waves is called interference.

If at a given location, both interfering waves are supersede in the same direction (both up or both down) then it is known as constructive interference.

p is the frequency of the dominant allele,  

q is the frequency of the recessive allele.

The genotypic frequencies after one generation are  

p² (H0m0zyg0us dominant genotypic frequency),

how does one type of rock is transformed to another type of rock?

Answers

Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

Answer:

This can happen through the rock cycle. But there are 3 processes which are crystalization, erosion and sedimentation, and metamorphism.

Explanation:

There are several types of rocks, but only one large furnace in which parts of a single large rock are cooked and changed into the various types of rocks. Our planet is a massive rock and a massive furnace. All rocks are divided into three categories, or classes. They're classified as sedimentary, metamorphic, or igneous, with variances in how they're generated.

I'll show you a schematic of the Rock Cycle instead of a detailed answer. It shows how one type of rock may be converted (metamorphic) into another under certain conditions. Just bear in mind that some types of rocks, such as sedimentary rocks, may form in a matter of hours, while others, such as metamorphic rocks, take millions of years to create.
