Answer:
C. carbon, hydrogen, and oxygen
Answer:
AGU-CUA
Explanation:
An mRNA sequence is made using a DNA sequence as a template. The sequence is dictated by complementary base pairing.
DNA uses the bases A, T, C and G. A is complementary to T and G is complementary to C.
RNA uses the bases A, U, C and G. A is complementary to U and G is complementary to C.
When transcribing DNA to RNA:
- C is paired with G
- G is paired with C
- A is paired with U
- T is paired with A
Therefore, TCA-GAT is transcribed to AGU-CUA
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.
