In the mid-1800s, an Austrian monk named Gregor Mendel Opens in modal popup window began his own experiments with plants. Unlike his predecessors, he used rigorous scientific methods in his experiments.

Mendel conducted his experiments with pea plants, which he grew in the garden of his monastery. The plants are easy to grow, reproduce quickly, and have several distinct characteristics Opens in modal popup window , or features, that are easy to observe. Characteristics of pea plants include flower color, seed color, and pea pod shape.

<span>Moreover, Mendel knew that each characteristic exists as one of two traits Opens in modal popup window , or forms of the character. For example, the seed color characteristic exists as one of two traits: green or yellow.</span>

which statement is false about base stacking when nucleic acids are in a double-stranded conformation?

Lilit [14]

The statement that is false about base stacking is; B. Stacking interactions are hydrophilic in nature.

<h3>What is the truth about Base Stacking?</h3>

Base stacking is defined as a common arrangement of nucleobases that are found in the three dimensional structure of nucleic acids. Bases (or base pairs) are planar, and these planes stack at contact distance , excluding water and maximizing Van der Waals interactions.

Looking at the given options, the only one that can be said to be false about the defined base stacking above as regards nucleic acids is option B.

The missing options are;

A. Stacking interactions occur when two or more bases are positioned with their rings parallel to each other.

B. Stacking interactions are hydrophilic in nature.

C. Stacking involves a combination of van der Waals and dipole-dipole interactions between bases.

D. Base stacking helps to minimize contact of the bases with water.

E. Base stacking interactions are important in stabilizing the three-dimensional structure of nucleic acids.

Human blood type is determined by three alleles IA, IB, and IO. The alleles IA and IB are co-dominant to each other, and both ar

dlinn [17]

Explanation:

According to p²+q²+2pq=1 (Hardy-Weinberg equilibrium)

heterozygote allele will be always 2pq

<u>1. Population</u>

1. A blood group has two genotypes- IAIA and IAIO

The genotype frequency will be-

IAIA= 0.3 X 0.3 = 0.9

IAIO= (0.3 x 0.6) x 2= 0.36

Total genotype frequency = 0.9+ 0.36 =0.45 or 45%

Now 45% of 540,000= 2,43000 (A blood group)

2. B blood group has two genotypes- IAIB and IBIO

The genotype frequency will be-

IBIB= 0.1 x 0.1 = 0.1

IBIO= (0.1 x 0.6)-=0.12

Total genotype frequncy= 0.13 or 13%

popluation with B blood group= 13% of 540,000 will be 70,200

3. AB blood group is IAIB

2 x IAIB= (0.3 x 0.1) x 2= 0.6

popluation with B blood group= 6% of 540,000= 32,400

4. O blood group

2. Heterozygote

IBIO blood group

= (0.1 x 0.6) x 2

= 0.12 or 12%

= 12%
