which role do ribosomes play in protein synthesis? answer ribosomes provide a site for trna to bind to mrna. ribosomes function in transcription. ribosomes provide a source of amino acids. ribosomes translate dna code to rna code. i don't know yet
The correct answer is option D: ribosomes translate DNA code to RNA code.
During protein synthesis, ribosomes translate DNA code to RNA code.
Universally, ribosomes are responsible for the synthesis of proteins through the translation of genetic information with the help of mRNA as they code particular amino acids which are the key units of protein synthesis.
These are manufactured as a result of the processing of genetic code into messenger RNA i.e. mRNA through triplet RNA basis known as codons.
Moreover, ribosomes also function as catalysts to accelerate the process of protein formation by continuously supplying amino acids to the polypeptide chain.
During this reaction, transfer RNA i.e. tRNA server as a carrier of amino acids to ribosomal sites where translation of DNA code to RNA code occurs for protein synthesis.

Identify each description as typical of eukaryotic repressors or bacterial repressors. Leave unplaced the description that is not characteristic of either group.
RNA polymerase is directly inhibited by Eukaryotic Repressors when they attach to DNA-binding sites on the enzyme.
An operator downstream of the promoter site is bound by bacterial repressors, which prevent RNA polymerase from working.
How do activators and repressors function in eukaryotes?Eukaryotic cells have transcriptional inhibitors much like prokaryotic cells do. The binding of transcriptional repressors to enhancer or promoter regions prevents transcription. Repressors react to outside stimuli in a manner similar to transcriptional activators in order to block the binding of activating transcription factors.
What elements are necessary for eukaryotic transcription?Eukaryotes need transcription factors to bind to the promoter area first and then assist in enlisting the proper polymerase. The polymerase that transcribes mRNA is called RNA Polymerase II.

Not trying to be racist but uh....was Jesus actually white?- I WILL GIVE 100 POINTS AND BRAIN LIST TO THE PERSON WHO ANSWERS TRUTHFULLY!
Answer:
I'm pretty sure Jesus was white. In any paintings that were depicted of him he was a tall, pale, and thin man with light brown, long hair and a beard. I have a plate that hangs in my house on our wall with a picture of him and that is how he looks. And it also determined that he would have most likely looked like a typical Galilean Semite of his day. I believe that there were people of color in the biblical days but it was never proven that Jesus was, so I'm gonna say, no. Jesus is white.
Explanation:
Hope it helps! =D
Answer:
I would say no.
Explanation:
Despite the illustrations and paintings it would have been highly unlikely in the area he was born into to be white. I think the white illustrations may have just came from a prejudiced past when people actually believed race made someone better or worse.

when a molecule of oxygen moves from outside of a eukaryotic cell to eventually be reduced by complex iv of the electron transport chain, how many phospholipid bilayers does it need to cross?
Answer: You, like many other organisms, need oxygen to live. As you know if you’ve ever tried to hold your breath for too long, lack of oxygen can make you feel dizzy or even black out, and prolonged lack of oxygen can even cause death. But have you ever wondered why that’s the case, or what exactly your body does with all that oxygen?
As it turns out, the reason you need oxygen is so your cells can use this molecule during oxidative phosphorylation, the final stage of cellular respiration. Oxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.
So, where does oxygen fit into this picture? Oxygen sits at the end of the electron transport chain, where it accepts electrons and picks up protons to form water. If oxygen isn’t there to accept electrons (for instance, because a person is not breathing in enough oxygen), the electron transport chain will stop running, and ATP will no longer be produced by chemiosmosis. Without enough ATP, cells can’t carry out the reactions they need to function, and, after a long enough period of time, may even die.
In this article, we'll examine oxidative phosphorylation in depth, seeing how it provides most of the ready chemical energy (ATP) used by the cells in your body.
Overview: oxidative phosphorylation
Simple diagram of the electron transport chain. The electron transport chain is a series of proteins embedded in the inner mitochondrial membrane. In the matrix, NADH and FADH2 deposit their electrons in the chain (at the first and second complexes of the chain, respectively). The energetically "downhill" movement of electrons through the chain causes pumping of protons into the intermembrane space by the first, third, and fourth complexes. Finally, the electrons are passed to oxygen, which accepts them along with protons to form water. The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.
