Answer:
The genetic code that is a blueprint for our physical traits is called a <u>genotype.</u>
Explanation:
A genotype is the genetic makeup of an organism or group of organisms with reference to a single trait, set of traits, or an entire complex of traits. Whereas, a stereotype is a widely held but fixed and oversimplified image or idea of a particular type of person or thing. For instance, stereotyping someone as racist for supporting Trump.
Answer:
Gravity provides and attractive force that keeps the chunk of matter in orbit around the sun
Ribosomes perform the process of protein synthesis on messengerRNA to create a sequence of amino acids that are joined together, this is called a polypeptide chain.
Answer:
The ability of sequences within the leader mRNA to pair with one another and form stem-lopp structures
Explanation:
A form of feedback regulation controls the trp operon by regulating transcription termination, a mechanism referred to as Attenuation.
-In the presence of high concentrations of tryptophan, RNA polymerase ceases transcription shortly after initiation in a region called the leader sequence.
-If the concentration of tryptophan is low, transcription does not terminate until the entire operon is transcribed. The mechanism of attenuation links alternative RNA secondary structures to transcription termination.
-Immediately after transcription, RNA from the leader region folds into one of two alternative secondary structures.
-One of these structures is a transcription termination signal that stops RNA polymerase from continuing to the end of the operon.
-The alternative structure does not contain a transcription termination signal and allows transcription of a single mRNA that encodes all the structural genes.
-The decision as to which of the two alternative RNA structures formed is regulated by the concentration of tryptophan.
Answer:
The cell membranes controls what goes in and out by having protein channels that perform their role accordingly sometimes like funnels and like a pump in different cases.
When a channel open in the plasma membrane it allows molecule to pass through, in this case there is no requirement for energy so it is a passive transport.
Gases and food particles broke down in water must be assimilated and waste or harmful substance and molecules must be remove. For most cells, this type of selective transport of all materials all through the cell must happen through the plasma membrane.
