Question
In genetics, the 'TATA box' is a conserved DNA sequence found in the promoter region of many eukaryotic genes. It is recognized and bound by:
A. DNA ligase
B. RNA polymerase I
C. TATA-binding protein (TBP), a subunit of TFIID
D. The ribosome
Answer: Option C
Solution (By JKExamLibrary)
The TATA box (consensus sequence TATAAA) is a highly conserved DNA sequence located about 25-30 base pairs upstream of the transcription start site in the promoter region of many eukaryotic genes transcribed by RNA polymerase II. It is specifically recognized and bound by the TATA-binding protein (TBP), which is a crucial subunit of the general transcription factor TFIID. The binding of TBP initiates the assembly of the pre-initiation complex, including RNA polymerase II, allowing transcription to begin.

Question #1
The organ that removes old red blood cells and stores iron is the:
A. Kidney
B. Bone marrow
C. Liver
D. Spleen
Discuss

Correct Answer: Option A

Explanation:
The spleen filters blood, removing aged or damaged RBCs, recycles iron, and stores platelets. The liver also processes hemoglobin products, but the spleen is the primary organ for RBC removal. The kidneys filter blood but don't remove RBCs.

Correct Answer: Option A

Explanation:
Mammalia is the only class of animals that possess mammary glands, which produce milk to nourish their young ones. Other defining features of mammals include the presence of hair on the skin, external pinnae (ear flaps), a four-chambered heart, and being warm-blooded (homeothermic). Examples include humans, whales, and bats.

A. Photosynthesis
B. Transpiration
C. Nitrogen fixation
D. Respiration

Correct Answer: Option A

Explanation:
During photosynthesis, water is split (photolysis), releasing oxygen as a byproduct. Respiration consumes oxygen, nitrogen fixation uses nitrogenase, transpiration releases water vapor.
