Answer:
8%
Explanation:
DNA is a double-stranded molecule made up of nucleotides: A, T, G, and C. According to Chargaff, A + T + G + C = 100%, where Adenine (A) pairs with Thymine (T) while Guanine (G) pairs with Cytosine (C).
Since G pairs with C and A with T, there must be equal proportions of each nuceleotide pair i.e. A=T, G=C
If C= 42%, G is also 42%
We then have, 42 + 42 + A + T = 100
84 + A + T = 100
A + T = 100 - 84
A + T = 16%
If A and T is collectively 16% and each must contain equal proportion, therefore, A=T = 16/2 = 8%.
Hence, proportion of Adenine and Thymine in that DNA is 8%.
Smut are plant disease caused by
several species of fungi that affects plants such as, corn, wheat, and sorghum.
Smut is characterized by fungal spores which are infectious and can affect
different parts of the plant at the same time. The fungi attacks grain crops by
forming thick, fleshy, gall on the ear, tassel, stalk and leaves of the plant. Smut
are destructive to grain crops, with negative economic effects to the farmer.

Imagine a human disorder that is inherited as a dominant, X-linked trait. How would the frequency of this disorder vary between males and females?
A. Males would display this disorder with greater frequency than females.
B. Males and females would display this disorder with equal frequency.
C. Females would display this disorder with greater frequency than males.
Answer:
C. Females would display this disorder with greater frequency than males.
Explanation:
Most of the X-linked disorders are recessive. but if it is dominant, a dominant gene is carried on the X chromosome. So it will effect all the females being the dominant and doesnot effect males more than females.
Hence option C. Females would display this disorder with greater frequency than males is the right answer.

Explanation:
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.
Answer:
Mendels studies predicted inheritance in a simple manner by studying traits which were not continuous or polygenic. Hence, the patterns of Mendel's observations were simple.
But there are certain traits which are polygenic that means depending on more than one gene type and there are other traits which are continuous. These kinds of traits have complex inheritance patterns and cannot be predicted through laws of Mendel.
