Recall the three discoveries Erwin Chargaff made while studying DNA: the total amount of pyrimidines (T+C) equals the total amou

nt of purines (A+G), the amount of T equals the amount of A, and the amount of G equals the amount of C. These three "rules" led to what conclusion(s) about DNA base pairing?
A purine base pairs with a pyrimidine base.

A pairs with T.

G pairs with C.

All of the answer options are correct.

Answer:

All of the answer options are correct.

Explanation:

Chargaff contributed in understanding the structure and composition of DNA with his discoveries. He discovered that purine and pyrimidine bases are in equal amounts in a DNA molecule. He also discovered that amount of Adenine base (A) is equal to amount of Thymine base (T). It means that A pairs with T. Since A is a purine and T is a pyrimidine it also implies that purine base pairs with a pyrimidine base. This conclusion can also be arrived by taking in consideration the other base pair which is G (purine) and C (pyrimidine).

A cross between the two parents results in 50 offspring. How many of the offspring are most likely to have the dominant trait?
romanna [79]

As  you see on the table, there are 3 ways the offspring can get the dominant trait. RR, Rr, and rR (order was switched for clarification). There are 4 total outcomes. In this case, the problem can just be treated as a probability question.

3 out of 4, or 3/4 * 50 is 37.5, which can be rounded to D. 38.

Is fluorine 2 a double bond
zepelin [54]
In F2 the bonding is pure covalent, with the bonding electrons shared equally between the two fluorine atoms. In HF, there is also a shared pair of bonding electrons, but the shared pair is drawn more closely to the fluorine atom. This is called a polar covalent bond as opposed to the pure covalent bond in F2.
