A hypothesis is a general principle or explanation that is derived from observations. Suppose you make the following observation
mr_godi [17]

Question continued

For each statement below, mark "True" if it would be a valid hypothesis, based on these three observations alone, and mark "False" if it would not be a valid hypothesis.

1. The onion cells I looked at have a nucleus.

2. All onion cells have a nucleus.

3. All cells have a nucleus.

4. Some cells have a nucleus.

5. Only onion cells have a nucleus.

6. If I look at 10 skin cells from my hand, each one will have a nucleus.

Answer:

1. The onion cells I looked at have a nucleus. false - this is not a hypothesis, it is an observation of the evidence you collected.

2. All onion cells have a nucleus. true - this is a valid hypothesis based on the evidence you have gathered from looking at onions

3. All cells have a nucleus. true  - this is a hypothesis based on you looking at 3 cell types, several samples of each, and finding that they all have a nucleus

4. Some cells have a nucleus. false - this is not a valid hypothesis. Your evidence so far suggests all cells have a nucleus

5. Only onion cells have a nucleus. - false, you know this to be false as other cell types you analysed had a nucleus

6. If I look at 10 skin cells from my hand, each one will have a nucleus. false - a hypothesis is supposed to be a general principle that is backed up by evidence, this is too specific.

Gene expression—translation how do cells synthesize polypeptides and convert them to functional proteins?
slavikrds [6]
The language of DNA in form of nitrogen bases read in a set of three termed as codons and it is being translated as language of proteins.

First mRNA is read according to the genetic code which can relate the amino acid sequence to proteins. mRNA can be use as the template to assemble in order the chain of amino acid. Translation starts when the mRNA is decoded and the sequence is elongated  until creating an amino acid sequence. Once the stop codon is reached, translation will be stopped and ribosome will release the polypeptide.
