Answer:
miRNAs are short sequences of RNA (20-24pb) with high self-complementarity, allowing it to fold over itself (hair fork structure). This makes miRNA super stable, even in the highly reactive atmosphere of the cytoplasm.
miRNAs do not have RBPs as in RNAm. They are linked with different proteins of the post-transducer machenary, such as argonaute, DICER or others, to serve as a guide to the adequate protein complex.
Answer:
True
Explanation:
In cell biology, the centrosome is the main microtubule organizing center that is important for cell division. The major function of the centrosome is to maintain the chromosome number during cell division.
Other function of centrosome during cell division include initiate the changes in cell membrane shape through phagocytosis and organize microtubules in mitosis that ensures the distribution of the centrosomes into daughter cell.
Hence, the given statement is true.
Transcription takes the DNA and copies/transcribes it to mRNA. Therefore, the right answer is b
Let us solve first the
phenotype of this problem.
Starchy grain = AA (dominant)
Sugary Corn = aa (recessive)
AA x aa = AaAa ; AaAa
<span> A A</span>
<span>a Aa Aa</span>
<span>a Aa Aa</span>
The result of the cross is
that the progeny will become heterozygous.
<span>If there is 58 progeny
sugary, there will also be 58 starchy. It is 50%.</span>
