Answer:
The Trypanosoma most closely resembles green algae.
Explanation:
Trypanosoma exhibits structural similarities to green algae, which is unicellular. The primary similarity between Trypanosoma and green algae lies in their flagella, both utilizing them for movement from one location to another. Both are unicellular organisms where a single cell manages all life processes.
Answer:
Option (A).
Explanation:
The lac operon system in bacteria elucidates the process of lactose metabolism within the cell. The initial operon system was identified by Jacob and Monod. An operon is characterized as a cluster of genes transcribed together as a single RNA unit.
When both glucose and lactose are available in the media, the bacterium favors metabolizing glucose. The presence of glucose is recognized by the bacterial cell as the CAP-cAMP complex is essential for transcription, and its levels are reduced in glucose's presence. This mechanism effectively halts the transcription of lactose genes even when lactose is available.
Consequently, the right answer is option (A).
Answer:
As defined by the genetic code, the amino acids include:
- Glycine: encoded by GGC, GGA, and GGG codons
- Arginine: encoded by AGA and AGG codons
- Lysine: encoded by AAA and AAG codons
- Glutamic acid: represented by GAA and GAG codons
Explanation:
The likelihood of observing an amino acid comprised of Glutamic acid in the coding sequence stands at 2/9 for each codon
