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.
Answer:
Cohabitation generally refers to people who, regardless of gender, live together without being validly married to each other. In the past, these relationships were called extramarital cohabitation. Sex and the law deals with the regulation by law of human sexual activity. Sex laws vary from one place or jurisdiction to another, and have varied over time, and unlawful sexual acts are also called sex crimes.
Explanation:
B.) A food chain shows only a single pathway of energy.
Remember that food web are made out of lots of food chains combine. Food chain is only one pathway.
