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.
I think it’s true because they contain a code with a specific protein that function s in one or more types of cells
1. What is the blending theory of inheritance? Why did Mendel question this theory? The theory is that offspring have a blend, or mix, of the characteristics of their.
Growth / development.
Replace dead cells / repair areas of the body e.g. wounds.
Make more cells for a specific function, e.g. White blood cells if infected.
Answer:
Wegener
Explanation:
Wegener, who was born on November 1, 1880, became well-known around the world owing to his theory that the continents and oceans developed due to continental drift. While his theory is fundamental to today's understanding of plate tectonics it was largely rejected by other scientists during his lifetime.
