Uhm what? i’m very confused lol
Answer: CAAUUGGCUAACGGUAA
Explanation: tRNA interprets mRNA code during translation so it is the job of tRNA to match the amino acids with the correct codons on the mRNA strands. According to the base pair rule of RNA, Adenine and Uracil (A -U) are base complements while Guanine and Cytosine (G - C) are base complements. So if;
mRNA: GUUAACCGAUUGCCAUU
then,
tRNA: CAAUUGGCUAACGGUAA.
Answer:
B
Explanation:
It is believed that the carbon stored in ancient dead plants is what makes up fossil fuels.
The prefix "poly-" means "more than one" and the suffix "-spermy" is clearly related to sperm. Accordingly, polyspermy is when more than one sperm fertilizes an egg, something that organisms try to avoid.
To avoid this extra fertilization, specific organisms can use "electrical polyspermy blocks" (the fast process), which changes the negative electrical charge of the egg to positive, thus repelling the also positively charged sperm. The slower prevention process is when an organism undergoes a secretion reaction, or a cortisol reaction, which contributes to envelopping the egg by changing its membrane.
