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.
I don't think that is right !!! .....some planktons can be eaten and it is not release cO2 back in air. so false !
The answer is Letter B. evaporation > condensation > sublimation When water evaporates, its latent heat of evaporation absorbs heat.
When water vapor condenses and forms a liquid, its latent heat of condensation releases heat to the environment; this is what powers hurricanes.
Answer:
An anode is any electrode where oxidation takes place
Explanation:
A simple example is electrolysis of water. A positively charged platinum electrode where H2 gas is oxidized to H+ ions is the anode.
