Restriction enzyme HinfI cleaves a five nucleotide DNA sequence GA(A/T)TC. The ambiguity in the central position - (A/T) - means
Afina-wow [57]

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.

Which statement about neural reflex arcs is incorrect? Which statement about neural reflex arcs is incorrect? Their function is
olchik [2.2K]

Answer:

The incorrect statement is that the neural reflex arc becomes slow by the hormones involved.

Explanation:

A neural pathway that controls a reflex is known as a reflex arc. In a reflex arc, the sensory neuron transmits a signal to the interneuron and stimulates it. The interneuron then transmits or passes the signal to the next neuron, that is, a motor neuron. The motor neuron associates with the interneurons in the spinal cord, which transmits messages from the CNS to the body. Thus, a reflex arc comprises the elements, that is, the receptor, integrating center, and the effector. Their main activity is to protect the body from external events.
