Answer:
F-actin is a double helical filament as opposed to G-actin,which is a globular protein .Each actin filament has two ends,called the plus and
the minus ends, which makes it recognizable from each other.This gives the structure a distinct polarity.
Explanation:
Actin is the most abundant protein that is found in almost all eukaryotic cells.Its a most important part cytoskeleton as its a monomeric subunits(size 42kDa) of two types of filaments i.e. microfilaments and thin filaments in cells. Actin is essentially required to maintain stability and morphogenesis of cell.It is involved in numerous significant processes such as endocytosis,cell division and migration.Actin is present in two forms:
•G-actin
•F-actin
The two forms of actin are different structurally.
G- actin is a globular shaped protein,usually present in free form(a monomer),having a tight binding site for another actin monomer.Each monomer has ATP. Upon polymerization of G-actin monomers, a polymer called F-actin filaments is form. This process is driven by hydrolysis of ATP.
Answer:
The loss of protein x function would lead to an increase in intracellular potassium ion ( K+) concentration
Deforestation is the removal of trees and plant life from a given area. with the absence of plant life comes the absence of photo-synthases. This causes a drop in the production of oxygen.
Answer:
The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.
Answer:
The correct option for the phenotypic ratio in this case is the following
9 : 6 : 1
Explanation:
In order to calculate the ratio, divide the two larger numbers each by the smallest one - which here would be 17.
So, 147 ÷ 17 = 8.7 (rounded off to 9)
And 93 ÷ 17 = 5.6 (rounded off to 6)
This way, '17' is considered as 1. Hence,
Gold : silver : bronze
9 : 6 : 1
