These substances are all mutagens.

<h3>What purposes do mutagens serve?</h3>

Many mutagens are employed to kill cancer cells because they are very harmful to growing cells. Chemotherapy may involve the use of intercalating drugs like daunorubicin and doxorubicin as well as alkylating agents like cyclophosphamide and cisplatin.

<h3>What consequences do mutagens have?</h3>

Additionally, lesions that increase the number of single-stranded regions in the genome may be introduced by mutagens that rapidly degrade DNA, leading to even higher frequencies of recombination.

<h3>How do mutagens cause harm?</h3>

A mutagen is a substance that can permanently alter cells' genetic material, perhaps resulting in heritable genetic harm or cancer.

Approximately 16% of this alien genome is comprised of nucleotides containing C, and 22% is comprised of nucleotides containing
Elan Coil [88]

Answer:

(a) <u>16</u> % of the alien genome is comprised of G.

(b) 17% of the alien genome is comprised of T.

(c) 17% of the alien genome is comprised of A.

(d) <u>22</u> % of the alien genome is comprised of X.

Explanation:

Assuming the alien follows Chargaff's rules which states that DNA from any cell of any organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases.

So if:

16% contains C ; 16 % pairs with G = 32% C-G pairing.

22% contains Y ; 22 % pairs with X = 44% X-Y pairing.

44% G-C + 32% X-Y =  76%

100%-76% = 34% the remaining should be split between T and A which is 17% each one.
