What else can I help you with?
What is the subunit of a ribosome holds onto the mRNA strand?
The ribosomal subunit of a ribosome holds onto the mRNA strand
What holds the messenger RNA in place during protein assembly?
The two subunits of the ribosome.
What regions of a ribosome holds the growing polypeptide?
The P site and the A site of the ribosome hold the growing polypeptide chain during translation. The P site is where the tRNA carrying the growing polypeptide is located, and the A site is where the new tRNA carrying the next amino acid in the sequence enters.
A bacterium has one that holds its genetic material?
yes. it has only one chromosome that holds its genetic material, however they may also have plasmids that contain genetic material
Where are proteins made and are attached to the endoplasmic reticulum?
Proteins are made by ribosomes in the cytoplasm and can be attached to the endoplasmic reticulum for further processing and sorting. This attachment occurs when the ribosome translates a signal sequence on the protein that directs it to the endoplasmic reticulum for insertion.
How are cells in polar bears and single body cells of a bacterium alike?
a fat cell in a polar bear holds more heat and travel in lumps mean while a single body cell travels by its self
How many binding sites does a ribosome have?
3, the A P E sites(they stand for something but i for got exactly what except for E for exit) A for amino acids entering, P for the amino acids to join together and E for the transport things to E exit
What is the role of the Nucleolus in the cell?
The nucleolus is responsible for producing ribosomes in the cell. It serves as the site of ribosomal RNA synthesis and ribosome assembly. Ribosomes are essential for protein synthesis in the cell.
Why aren't STDs transmitted by casual contact?
One example of an STD causing bacterium is Haemophilus ducreyi. It is transmitted sexually. Your question is what would happen if someone were to cover your arm with this bacterium? Absolutely nothing. The reason is that this bacterium requires special nutrients to stay alive. Even in the lab, we cannot grow this bacterium on standard agar, but rather a special one called chocolate agar with factor V and factor X. Likewise, while this bacterium thrives in your genital area, it cannot sustain itself on your skin. There are simply no nutrients for it. It dies. This is why sexual contact is needed, so that the bacterium can go from one hospitable environment to another, without being exposed to the outside environment where it will die. The same concept holds true for all STD's.
The sites A P and E are occupied by amino acids being assembled into a chain of polypeptide what are they part of?
The sites A, P, and E are part of the ribosome, the cellular machinery responsible for protein synthesis. The A site binds incoming aminoacyl-tRNA, the P site holds the growing polypeptide chain, and the E site exits the empty tRNA after its amino acid is transferred to the growing chain.
One binding site on a ribosome holds an mRNA molecule and the other two binding?
sites hold tRNA molecules. The mRNA binding site is where the mRNA molecule binds and is read during translation. The tRNA binding sites are where tRNAs carrying amino acids bind and deliver them to the growing polypeptide chain.
How many quarts does a 1996 dodge ram 3500 take for an oil change?
V8 holds 5V10 holds 7Diesel holds 12V8 holds 5V10 holds 7Diesel holds 12
