Explanation: that's why i think i really didn't understood the question
Answer:
E.bind to complementary regions of target mRNAs
A.The rate of accumulation of the polypeptide encoded by the target mRNA is reduced.
Explanation:
A researcher introduces double-stranded miRNA into a culture of mammalian cells and can identify its location or that of its smaller subsections experimentally, using a fluorescent probe. Sometime later, she finds that the introduced miRNA separates into single-stranded RNAs, one of which is degraded. Use this information to answer questions 1 and 2.
microRNAs (miRNAs) are a class of ∼22-nt noncoding RNAs(Ribonucleic Acids) that regulates gene expression in plants and animals. Precursor miRNA hairpins are mostly cut by Dicer in the cytoplasm to manufacture a double-stranded. when a double stranded miRNA separates into single stranded RNAs it is actually that it is attached to the complementary region of target mRNA
When she finds that the introduced miRNA separates into single-stranded RNAs, what other evidence of this single-stranded RNA activity can she find?
it means that:
The rate of accumulation of the polypeptide encoded by the target mRNA is reduced.
Answer:
Eukaryotic cells evolved from prokaryotic cells.
Explanation:
The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are believed to have been developed over time.
The mitochondria isn't considered to be part of the endomembrane system because its structure is not derived from the nuclear envelope, ER, GolgiApparatus, or cell membrane.
