This is a process called transcription and translation.
Information to synthesize a particular protein is found in DNA in the cell nucleus. This information is copied (transcribed) onto messenger RNA or mRNA in short. The copying process is called transcription.
mRNA then leaves the nucleus and enters the cytoplasm where it attaches to a ribosome. Transfer RNA or tRNA then begins to read (translate) the information on the attached mRNA. This is the process of translation.
tRNA then fetches amino acids that correspond to this information and brings them to the ribosome where they are linked together into a chain. This chain of amino acids is the primary structure of the protein.
Well for starters, producers are living organisms that produce their own food. Like plants. And plants ironically provide us humans with oxygen as they live off of the carbon dioxide we produce. Some plants are also main vegetables that we eat, so put simply, a world without producers would be practically oxygen-less and vegetable-less.
Answer:
mRNA is produced in the nucleus.
Answer:
The invention of the marine chronometer by John Harrison in the middle of the 18th century made true ocean navigation possible. (1) Marine Chronometer In the early 18 th century, knowing your whereabouts on the face of the globe was difficult. As the world’s greatest global power, Britain was extremely keen to remedy that.
Answer:
D. antigen only come from microbes
Explanation:
Antigens are substances which elicits a response by the antibodies. Antigens Antigens include proteins, nucleic acids, lipoproteins, glycoproteins, and certain large polysaccharides.
They parts of antigen molecules that initiate immune responses are called epitopes or antigenic determinants.
