Answer:
messenger RNA
Explanation:
Answer:
messenger RNA (mRNA)
Explanation:
mRNA is responsible for transcribing the bases of DNA into a blueprint for making proteins
Answer:
A patient is admitted to the emergency room because of uncontrollable flailing arms.After a quick test we determine the cell membranes in their arm nerves are damaged and the cells are not signalling properly. They are endoplasmic proteins.
Explanation:
The endoplasmic reticulum have many functions including the folding of proteins in many sacs called cisternae and the transport of synthesized proteins in vesicle to Golgi apparatus. RER is made up of cisternae, tubules and vesicles.The cisternae are made up of flattened membrane discs which are involved in the modification of proteins.The main function of smooth endoplasmic reticulum is to make cellular products like hormones and lipids.The type of RNA that contains the information for making protein is called messenger RNA or mRNA because it carries the information or message from DNA out of the nucleus into the cytoplasm.Through the process of transcription and translation the information from the genes is used to make proteins.
Well if endoplasmic reticulum stops working there would be many enzymatic processes which would not occur ultimately leading to the death of many cells. Example of protein deficiency is kwashiorkor.Symptoms include fatty liver, flaky skin,diarrhoea, apathy ,failure to grow,edema of belly and legs.This edema is explained by the action of lipoxygenase on arachidonic acid to form leucotrienes and the normal functioning of proteins in fluid balance and lipoprotein transports. Dietary sources of proteins are milk, meats and eggs.Soy and quinoa are vegetable sources of complete proteins.Combining red beans or lentils with wholegrain rice or peanut butter with wholemeal bread also provides complete protein.

Explanation:
b. lac repressor
c. RNA polymerase
d. lac repressor and RNA polymerase
e. cAMP receptor protein (CRP) and RNA polymerase
Answer:
e. cAMP receptor protein (CRP) and RNA polymerase.
Explanation:
Lac operon is a type of inducible operon which can be controlled positively or negatively. A positively controlled operon is the one which is controlled through an activator while negatively controlled is the one which is controlled through a repressor. The inducer in case of lac operon is cAMP receptor protein (CRP) which forms a dimer and makes interaction in the upstream region of promoter of lac operon so as to facilitate transcription. Repressor in case of lac operon is a tetrameric protein which binds the operator region of lac operon and prevents gene expression by restricting RNA polymerase from facilitating transcription.
When lactose is present in high concentrations and glucose is in low concentration in the culture medium for a wild type E. coli strain, the control will be negative as well as positive.
If the glucose level is very low, an enzyme known as adenylyl cyclase becomes active and produces cAMP, this cAMP then forms a dimer by interacting with CRP to form a cAMP-CRP dimer which acts as an activator and binds to the upstream of lac promoter and helps RNA polymerase to initiate transcription.
Also because of high lactose concentration, lactose isomerises into allolactose which acts as an inducer and interacts with repressor to remove it from operator region. As soon as repressor is removed from the operator region, RNA polymerase starts transcription.
b. parasympathetic motor division
c. sympathetic sensory division
d. parasympathetic sensory division
Answer:
i believe its c
Explanation:
A single sympathetic preganglionic fiber has many axon collaterals and may synapse with 20 or more postganglionic neurons.
The postganglionic axons typically terminate in several visceral effectors and therefore the effects of sympathetic stimulation are more widespread than the effects of parasympathetic stimulation.
