Answer:
Option D, Zinc is higher on the activity series because there is clear evidence of a reaction.
Explanation:
It is very clear that a metal which is higher in activity will replace a metal having lower activity.
Since, Zinc has higher activity than copper, it is very sure that it in a copper chloride solution it will replace copper and produce zinc chloride solution leaving behind copper as residue.
Residues of copper is a clear evidence of reaction
The chemical equation for this reaction would be -
Hence, option D is correct
Answer:
This means that one amino acid can be coded by more that one codon.
Explanation:
A triplet code that code for an amino acid during translation is called genetic code. The genetic code is said to be redundant because a single amino acid can be coded by more that one triplet codon.
So there can be synonymous codon for one amino acid. For example, leucine, serine, and arginine have 6 synonymous codons.
The genetic code is unambiguous also because each triplet codon can only code for a particular single amino acid. Genetic code is also universal which means the same code is used in all life forms.
Answer:
C
Explanation:
Semiconservative replication means that strand will also be used. (Pretty sure)
Answer:
Endoplasmic reticulum.
Explanation:
Protein synthesis, sorting and transport is the important mechanism for the synthesis of protein in the body and the transport of the protein to its specific site or organ. The protein must reaches to its final destination for its proper functioning.
KDEL ( K- leucine, D is aspartic acid, E is glutamic acid and L is lysine ) is the stretch of a specific amino acid that are responsible for the protein molecule to target at its specific site. KDEL is specific for the transport of peptides to the endoplasmic reticulum.
Thus, the correct answer is option (A).
ADP (adenosine diphosphate)
