Genetic engineering is applied to techniques like DNA cloning in which the steps are: step 1: DNA cutting from the parent source; step 2: DNA cut is pasted into the matrix to be modified; step 3: matrix is introduced to the host cell and step 4, vector DNA is isolated. Answer then is B.
Glycolysis takes place in the cytoplasm. Cellular respiration takes place in the mitochondria.
Answer:
D
Explanation:
A substitution is where a base is substituted by another base
A. ATGAT - this is not a substitution, the C has been <u>deleted</u>
B. UAGCUA - this is not a substitution, but is the complementary mRNA sequence (you can tell because there are Us instead of Ts)
C. TAGCTA - this is not a substitution, but is the complementary DNA sequence
D. ATGGAT - this is a substitution, the C in the original sequence has been replaced (substituted) by a G.
