Answer:
The correct answer is option a. "7.1".
Explanation:
One easy way to determine if a peptide sequence is acidic, basic or neutral is to check for the number of amino acid residues that are acidic, basic or neutral. In this case, most amino acid residues are neutral, which mean that under neutral conditions they have a pKa close to 7.0. Particularly, the content of 3 leucine, 2 alanine and 2 glycine residues determines that the peptide have a pI of around 7.1.

evidence is discovered
I think the correct answer from the choices listed above is option D. The chain of amino acid that corresponds to the nucleotide sequence CCUGAUUCC would be Leucine–valine–phenylalanine. Hope this answers the question. Have a nice day.
Answer:
The correct answer is A bacteriophages inject only DNA into the bacteria.
Explanation:
Bacteriophages are a specific type of virus that infect bacteria.During the course of infection bacteriophage releases an enzyme known as lysozyme which creates a hole in the cell wall of the bacteria.
After doing that(creating a hole) bacteriophage inject its DNA inside the bacterium.
The injected DNA undergo gene expression by utilizing the gene expression machinery of bacteria which ultimately result in the formation of coat protein.The DNA is then packed within the coat protein to form progeny phages.The progeny phages then disrupt the cell wall and get released from the bacterium in search of a new host.
