The phrase "are needed for assembly" is correct and usable in written English.
It can be used when discussing the requirements or components necessary for putting something together, such as a product or a project.
Example: "The following tools and materials are needed for assembly: screws, a screwdriver, and a hammer."
Alternatives: "are required for assembly" or "are essential for assembly".
We show in this study that CCT subunits are needed for assembly of cilia and maintenance of axoneme structure, especially at the tips of cilia.
New approaches are needed for assembly and for binning the sequences, and a new conceptual approach to annotation, in which the community is involved through a wiki environment, will be essential.
The antisense strands later hybridized to the sense siRNA were synthesized using an automated RNA synthesizer (Mermaid) as no chemical modifications were needed for assembly on the nanoparticle surface.
However, aging and oxidative stress could induce inefficient functioning of mitochondria causing impaired metabolism of branched or aromatic amino acids (e.g., phenylalanine, tyrosine) and energy-requiring protein biosynthesis that are needed for proper assembly and architectural integrity of tissues.
Flagellar gene expression is temporally regulated to produce proteins as they are needed for flagellar assembly.
Chd1 works in conjunction with histone chaperones both are needed for chromatin assembly, and so are DNA, histones and ATP.
It is probable that more factors are needed for the assembly of a functional complex, but that the genetic approaches used to date have not been able to identify them.
Assuming that 360 molecules of VP1 protein are needed for the assembly of one VLP [ 7] the calculated number of VP1 molecules was divided by 360 to determine the number of VLPs in the respective VLP preparation (VP1/scFv-VP2 VLPs and VP1/scFv-Fc-VP2 VLPs).
Multi-protein building blocks reduce the number of steps that are needed for self-assembly of adhesion sites and therefore can make this process less prone to errors, thereby also faster.
Both the N-terminal and the C-terminal part of dynactin2 are needed for proper self-assembly and binding to dynactin3.
HIV 1 PR is one of the main targets of Acquired Immuno-Deficiency Syndrome therapies as it performs an essential function in the HIV life cycle by cleaving the viral poly-protein and producing the components that are needed for the mature virus assembly.
