A protein that has a helix-turn-heloix domain can bind to DNA because one of the helices interacts with the sugar phosphate backbone of a DNA strand while the other helix binds to the base bairs in the major groove. The section of the helix-turn-helix motif that binds inside the major groove is called the "recognition sequence"
Ribosomes are the cell organelles responsible for protein synthesis. They can be found either free in the cytoplasm or attached to the endoplasmic reticulum.
T cells are the cells directly responsible for cellular immunity. They recognize infected cells or aberrant cells and work to eliminate them from the body.
The circulatory system is directly responsible for transporting oxygen, nutrients, hormones, and waste products throughout the body. It consists of the heart, blood vessels, and blood, working together to ensure proper distribution of essential substances to all tissues and organs.
B lymphocytes are the formed elements most directly responsible for humoral immunity. They produce antibodies that circulate in the bloodstream and bind to antigens, marking them for destruction by other immune cells.
No, AGG is not a codon. Codons are three-nucleotide sequences in mRNA that code for specific amino acids during protein synthesis. AGG is a nucleotide sequence present in DNA but does not directly code for an amino acid.
Enhancers do not directly bind to repressor proteins. Enhancers typically bind to activator proteins, which in turn help recruit RNA polymerase to the promoter region of a gene, leading to gene transcription. Repressor proteins, on the other hand, bind to specific DNA sequences to inhibit gene transcription.
Meiotic cell division in animals is directly responsible for the producing sex cells.
Not directly.
Ribosomes are the cell organelles responsible for protein synthesis. They can be found either free in the cytoplasm or attached to the endoplasmic reticulum.
Slavery was directly responsible for the Civil Rights Movement of the 1960s.
