non-disjunction is a pathological event that occurs during the second anaphase in meiosis when sister chromatids are not separated. As a result one of the resulting cells will have 1 extra chromosome and the other will be 1 short. An example of a non-disjunction that can occur in humans is Down syndrome that has a frequency of about 1/1000 people. It is caused by the non-disjunction of the 21st pair of chromosomes.
Answer:
The correct answer is b) Food → Glycolysis → Krebs cycle → Electron transport chain.
Explanation:
When food enters the organism it goes through a lot of processes to become the beginning of glycolysis which produces pyruvate, which turns into acetyl CoA, which at the same time is the beginning material of Krebs cycle. The products of this cycle provide energy for the electron transport chain (NAD(H) and FAD(H)).
<span>Translation
</span>Remember that transcription happens in the nucleus as it changes from DNA
to mRNA. In translation,
the mRNA first has to leave the
nucleus and go into the cytoplasm of the cell.
The process of translation actually occurs in the cell’s ribosomes.
<span>
</span>The process of translation uses the genetic code on the mRNA strand to
direct the construction (making) of a protein molecule. <span>
</span>1. A ribosome attaches to an mRNA
molecule in the cytoplasm.<span>
</span>2. As each codon passes through the
ribosome, tRNA molecules bring the matching amino acids into the ribosome. Each tRNA has a set of 3 unpaired nitrogenous
bases called an anticodon which matches up with the codon coming through the
ribosome. So one end of a tRNA has an
anticodon and the other end carries the amino acid which is how the code is
translated.<span>
</span>3. The ribosome and the rRNA
molecules it contains attach the amino acids together as they are being
translated. The protein chain will keep
growing until the ribosome reaches the stop codon on the mRNA. At that point, translation is done and the
ribosome lets go.
Hope this helps!!!
The moon has different phases because it’s around different times. For example, let’s say you go outside and look at the moon at 11pm, then you go and look at it again at 12 pm, it’s going to have a different phase because it’s not at the say time.
I hope this helps! This is what I was getting from the question
