Bacterial Morphology
The bacteria are prokaryotic organisms that are single-celled, and are found to exist as free-living and possess a microscopic size. The morphology is found to vary in the bacteria, where some of them are identified as individual organisms and the others are detected as colonies. The size and shape of the bacterial cell also represent its morphology.
Bacterial cell structure
Bacteria are single-celled, tiny creatures that may enter healthy tissues and grow rapidly. Bacteria are microscopic organisms that are tiny and unicellular. These are members of the prokaryote kingdom. They live in water, air, soil, and all-natural environments. They are used in industrial and therapeutic processes, and they support a wide range of plant and animal life. The first organism to appear on the planet. Bacteria-like creatures are the oldest known fossils. Bacteria can consume a wide range of organic and inorganic elements, and some may even survive in harsh conditions.
Question
Transcribed Image Text:D. Evidence from Molecular Biology
Many organisms have similar molecules of life (RNA, DNA, proteins) that suggest descent from a
common ancestor with modifications. The near universality of the genetic code reflects an evidence
of common ancestry and relatedness and can be inferred from the similarities in the DNA sequences
between and among organisms.
D.1 Cytochrome e is a protein found in mitochondria. It is used in the study of evolutionary relationships
because most animals have this protein. Cytochrome c is made of 104 amino acids joined together. Below
is a list of the amino acids in part of a cytochrome protein molecule for 9 different animals. The capital
letters indicate the different amino acids found in proteins. Encircle any amino acids in each species that
are different from the human sequence. When you finish, record how many differences you found in the
table on the next page. One species is done for you as an example.
