Answer:
C.Test for microtubule proteins, because only eukaryotes have microtubules.
Explanation:
Although some bacteria have similar cellular components, microtubules are only found in eukaryotic cells. This is why it is most likely that if it finds the components that form microtubules, the unidentified organism belongs to the group of Eukaryotes.
Answer and Explanation:
Prokaryotic Translation :
Initiation :
- First amino acid participating is f-methionine.
- Requires three initiation components are
, 
and 
- Initiation complex framed at Shine-Dalgarno succession of mRNA.
- There is no concept of Kojak rule in prokaryotic.
Protein synthesis :
- Faster process. Adds 20 amino acids per sec.
Termination :After translation, the formyl group of first formylated methionine is removed. Methionine is retained in the polypeptide chain
Eukaryotic Translation :
Initiation :
- First amino acid taking part in translation if methionine.
- Requires a set of eleven initiation factors, named as eIFn.
- Initiation complex formed at 5’ end of mRNA.
- Kojak rule followed
Protein synthesis :
- Slow process. Adds 1 amino acid per second.
- mRNA is mono-cistronic.
- Occurs on 80S ribosome.
Termination :
Initiating methionine codon is removed from the polypeptide chain.
Answer:
Neurons and glial cells
Explanation:
Neurons transmit electrochemical signals to one another through the exchange of neurotransmitters acorss synapses to accomplish commmunication. Glial cells function in forming myelin as well as protecting and supporting neurons.
Answer:
The trees will always be randomly spaced when young and will be regularly spaced when old.
Explanation:
The trees will always be randomly spaced when young and will be regularly spaced when old.
Answer:
An alteration in DNA that occurs after conception. Somatic mutations can occur in any of the cells of the body except the germ cells (sperm and egg) and therefore are not passed on to children. These alterations can (but do not always) cause cancer or other diseases.
Explanation:
when a skin stem cell harbors a cancer-driving mutation, it becomes more likely to generate two specialized skin cells when it divides. Over time, the mutated skin stem cell fails to renew itself and turns into cells that eventually slough off, allowing the skin to expel mutated cells as needed.
Errors in DNA copying during cell division and development can cause new mutations — called de novo mutations — at any time from the moment of conception. Mutations that occur in the germ line — the cells that develop into sperm or eggs — can be passed on to the next generation and, perhaps, cause disease in children.
