Chargaff's rule states that the amount of adenine in DNA is equal to the amount of thymine, and the amount of cytosine is equal to the amount of guanine. This principle underlies the complementary base pairing in DNA strands.

What is correct about Chargaff's rule for each species A adenine equals guanine B adenine equals thymine C adenine equals cytosine D adenine guanine thymine and cytosine amounts are equal?
C adenine equals thymine. Chargaff's rule states that in DNA, the amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine.
What is descent with principle is it that states that living species are descended from ancient ones?
The principle of descent with modification states that living species have evolved from common ancestors over time through the mechanism of natural selection. This concept, proposed by Charles Darwin, explains how species adapt and diversify in response to changing environments. It is a fundamental idea in the theory of evolution.
How many frog species are there in the world?
There are about 4740 species of frogs world-wide
What states that changes in species happen slowly over long time periods?
The theory of evolution, proposed by Charles Darwin, states that changes in species occur gradually over long periods of time through the process of natural selection. This theory suggests that new species arise from the accumulation of small, incremental changes in traits that are advantageous for survival and reproduction.
What is the principle of competitive exclusion principle?
The principle of competitive exclusion states that two species cannot occupy the same niche. If they do occupy the same niche, competition for food, space and limited resources will occur. Too much competition will occur until the best-adapted species cause the disappearance of the other.
How much percent of iron and lead are present in galena?
Galena typically contains around 86% lead and 14% sulfur. Iron is usually present in trace amounts in galena, less than 1%.
What are the names of the states of Hawaii?
Hawaii is one of the 50 US States. It contains Islands. It contains cities. It contains counties. It does not contain any countries or states.

Which regions of the unted states Contains only four states?
West region
How many fur-bearing species are there in the U.S.?
There are 23 fur-bearing species in the United States spread among all the states, except Hawaii.
What number sentence states that two amounts are equal?
This is called an equation.
What did Erwin Chargaff accomplish in his life?
Erwin Chargaff proposed two main rules in his lifetime which were appropriately named Chargaff's rules. The first and best known achievement was to show that in natural DNA the number of guanine units equals the number of cytosine units and the number of adenine units equals the number of thymine units. The second of Chargaff's rules is that the composition of DNA varies from one species to another, in particular in the relative amounts of A, G, T, and C bases. Such evidence of molecular diversity, which had been presumed absent from DNA, made DNA a more credible candidate for the genetic material than protein.
What species is an Americana?
Americana is the folklore and artifacts and history of the United States. I do not believe it has anything to do with a species.
Which theory states that the more recent species are change descendants of earlier species?
mostly eveloution
What is the name of the northern states?
New York is a state, it does not contain states. It contains counties.
How many species of butterfly's are there?
There are over 20,000 species of butterflies in the world. 725 of those are in the United States, nearly 2,000 species are found in Mexico.
