Answer:
b. Increase the length of the poly(A) tail of the mRNA prior to transfection.
Explanation:
Polyadenylation is the addition of a long chain of adenine (A) nucleotides at the 3' end during RNA processing. This resultant chain is known as poly(A) tail. A poly-A tail generally has a size of 100-250 residues long. The poly(A) tail increases the stability of the messenger mRNA prior to the translation by slowing down its degradation rate over time. The process of polyadenylation enables RNA transcripts to be exported from the nucleus in order to be translated by ribosomes in the cytoplasm.
Answer:
The two components that helps to maintain the homeostasis of the cell are 1 Buffer system 2 Membrane transport process
Explanation:
1 Buffer system Buffer system helps to maintain a constant PH in addition to small amount of acid or base .There are many buffer system present inside our body
A Bicarbonate buffer system helps to maintain concentration of carbon di oxide, bicarbonate ion and Carbonic acid according to our body"s need.
B Phosphate buffer system
C Hemoglobin buffer system This buffer system helps too maintain normal O2/CO2 ratio of our body which is very much important of maintain our body"s homeostasis.
2 Membrane Transport process Various ion channels of plasma membrane sych as Na+ K+ ATPase,Ca2+ATPase ,H+ ATPase helps maintain ionic homeostasis of our body.
<span>An element is a substance that cannot be broken into other substances further.An element is composed of one type of atoms all over. Like a molecule can be divided into atoms further. For example, Water is a molecule which is made up of Oxygen (O), Hydrogen (H). Here, Oxygen and Hydrogen are elements and cannot be further broken down into other substances.</span><span />
<span>The purpose of a 'no DNA' control reaction or negative-control reaction would be to know the protein level backgrounds (flourescence & endogenous biotinylated proteins) in the sample. If the gel lane has bands, it means that DNA is present. </span>
