Answer:
C) 2.0 kb
Explanation:
It is given that out of the 4 nucleotides A, T, C & G each one has equal probability to occur at any position on the DNA molecule which simply means that the probability of occurrence of any nucleotide at a position is 1/4.
Also, it is given that probability of occurrence of either A or T at 3rd position is equal which means that the probability at that particular position will be 2/4 = 1/2.
Now, GA(A/T)TC is the DNA sequence where Restriction enzyme HinfI cleaves so the total probability of an average HinfI cleavage fragment will be = 1/4 x 1/4 x 1/2 x 1/4 x 1/4 = 0.00195 = 0.2 i.e. 2 kb.
Answer:
Number 1. the flower; it has a reproductive function. They are the reproductive organs of the plant. They mediate sperm contained within pollen, to the ovules contained in the ovary.
Number 2. the leaf; their primary function is photosynthesis -manufacturing food for plants
Number 3. the stem; it's function is to provide support for leaves and flowers, they conduct water and nutrients from the roots and food in the form of glucose from the leaves to other plant parts.
Number 4. the roots; their function is to absorb water and minerals from the soil, anchor the plant in the soil and to store extra food for future use.
