Answer:
B. the action of microRNAs that block translation of specific mRNA molecule
C. the action of RNA–protein complexes that degrade the regulatory proteins responsible for initiating transcription.
Explanation:
RNA interference occurs what RNA prevent the translation of some gene this is done by neutralizing target mRNA molecule. It suppresses the effects of some desires genes through its action.
MicroRNA and small interfering RNA (miRNA and siRNA) are the major RNA that controls interference. siRNA and miRNA prevent translation by directing some enzmes complexes to denature the mRNA molecule needed for translation. They intiate post transcriptional splicing.
RNA interference is found in eukaryote and some animals and its initiated by enzyme Dicer that inhibits translation by degrading the enzymes action.
Answer:
<em>The chromosome number will not be constant and the person would die.</em>
Explanation:
During gamete formation, half of the chromosomes arise from one parent and the other half from the other parent. This is possible due to the process of meiosis.
If during gamete formation, the number of chromosome does not get reduced, then after fertilization the gamete will have double the number of chromosomes as compared to the parents. Hence, the chromosome number of the person will not remain constant and he/she would die.
Answer:
According to the BBC, Saber-tooth cats went extinct roughly 10,000 years ago and it is suggested that their closest living relative might not be the tiger or the lion, but the clouded leopard. The saber-toothed salmon is another animal that is extinct but there are some still alive today: walrus; musk deer and warthogs.
Explanation:
It has the same origin as other connective tissues and it connects all the body systems together.
