Answer:
A. UUA AAG GCU UAC CCU
Explanation:
Transcription is the first process of Gene expression, which involves the synthesizing of a mRNA molecule from a DNA strand. This process (transcription) which is carried out or catalyzed by an enzyme called RNA polymerase, uses the complementary base pairing rule to synthesize nucleotides.
The complementary base pairing rule as proposed by Chargaff states that Adenine base (A) should bond with Thymine base (T). Likewise for Guanine (G) and Cytosine (C). Hence, in a DNA strand with sequence: AAT TTC CGA ATG GGA, the following RNA will result:
UUA AAG GCU UAC CCU.
Note that, Uracil base replaced Thymine base in the mRNA molecule.
Since; A-U and G-C
AAT TTC CGA ATG GGA ---------- DNA
UUA AAG GCU UAC CCU --------- RNA
Hello!
The answer is D. Industrial Modification (also called Industrial melanism).
The history of the peppered moth is the following: The population of dark-colored peppered moths increased during the Industrial Revolution and decreased after it. Scientist studied this phenomenon and concluded that the dark color was an effective camouflage in the contaminated environment of the Industrial Revolution, but in a clean environment, birds can hunt dark peppered moths more easily and thus their population decreased after the Industrial Revolution when the environment was cleaner.
This is a classic example of how mutations are shaped by the environment, but it can't be called Natural Selection because the changes were produced by the Industrial Revolution and not by natural causes.
Over 50 amino acids in a chain are considered a protein.
I'm pretty sure that it is topsoil. My apologies if i'm mistaken.
