Answer 1

The F fertility factor is integrated into the chromosome in an Hfr strain, is free in the cytoplasm in an F+ strain, and is missing from an F- strain. Hfr marker genes become part of a stable exconjugant genome.

Here we can see the different amino acid properties.

*His indicates for the Histidine

*Leu Indicates for Leucine

*Pro indicates for proline

and

*Met indicates for Methionine

These are the different genomes detected for an organism and is considered as an Amino acid database
