Use the complementary rule: If we had a DNA strand of 20 nucleotides, and 6 of them

Biology
1 answer:
polet [3.4K]3 years ago
8 0

Answer:

6 thymine, 4 guanine. 4 cytosine

Explanation:

Adenine pairs with thymine, so you need 6 of each

Cytosine matches with guanine, but the total of nucleotides is 20, so

6(adenine)+6(thymine)=12

20-12=8

8= 4(guanine)+4(cytosine)

According to the pedigree chart, which statement MUST be true?
dem82 [27]

Answer:

<h3>A) Only Male offspring can inherit the disease. </h3>

Explanation:

As per the pedigree chart, only the males are shown as affected by the disease. Thus, it must be a sex-chromosomal inheritance, expressed in the Y chromosome or the male chromosome.  

As the females in the family are unaffected, hence the mother in the original parental generation cannot be a carrier.

It is likely that the father from the original parental generation might be the carrier.

As there are affected individuals in both the generation after the original parental generation ( the last generation having two more affected males), the statement that the chances of inheriting the decease with each successive generation is not true.
