The difference between the two phrases is that My hearts a stereo is classified as a metaphor for it defines the heart like a stereo without using the key words like or as, while the phrase, my loves like a red, red rose, is classified as a simile because it uses the key word like, the person describes his or her love like a red, red rose.
(of an immature or stem cell) capable of giving rise to several different cell types.
Answer:
ACA: Threonine
CAC: Histidine
Explanation:
To answer this question we need to remember that the ribosome reads every three bases or 'codon' in order to assign the right tRNA carrying the amino acid.
In the first artificial mRNA we see two patterns of three letter:
CAC and ACA.
In the second artificial mRNA we are able to identify three different patterns:
CAA
AAC
ACA
And they repeat, so we end with three different polypeptides: polythreonine, polyglutamine and polyasparagine. This will depend on the initial letter the ribosome starts reading.
The only amino acid that repeats in both artificial mRNAs is Threonine, and we see its pattern ACA also repeated.
So, we could assign this codon (ACA) to threonine.
We can then assume that the pattern CAC codifies for histidine since we only get this two polypeptides in the first mRNA.
Lastly with the information provided we cannot determine the codons AAC and CAA for glutamine or asparagine. We would need further experiments.
