Answer:

Possible options are:

a. the microbe would survive inside the phagocyte

b. the microbe would be expelled from the residual body

c. the microbe would be killed by the lysosome's enzymes

d. the microbe would cause the phagocyte to go through apoptosis

Answer is A

Explanation:

If microbe were capable of preventing a phagosome from fusing with a lysosomes it means microbes would survive inside phagocyte.The bacteria survive inside of phagosomes because they prevent the discharge of lysosomal contents into the phagosome environment. Specifically, phagolysosome formation is inhibited in the phagocyte.

Answer:

Please find what occurs in the single nucleotide-pair substitution below

Explanation:

Single nucleotide-pair substitution is a type of point mutation as stated in this question. Point mutation is when one nucleotide base (single) is affected in the sequence. In this single nucleotide-pair substitution, ONE nucleotide base is substituted by another base.

For example, in a DNA sequence that reads: TAA GTC GGG, a mutated sequence affected by single nucleotide-pair substitution will read as follows: TAA GTC TGG. Note that in the last codon (GGG), a single nucleotide G has been replaced by another nucleotide T. Therefore, single nucleotide-pair substitution is said to have occur.

What are ejcs? Describe the importance of the ejc complexes for the export and stability of mrnas.
Alex Ar [27]

Explanation:

The Exon Junction Complex (EJC) is a eukaryotic molecular machine that interacts with spliced mRNA upstream of exon-exon junctions, providing a binding platform for other trans-acting proteins that determine the fate of the mRNA.  The spliceosome deposits the ~335kD EJC in a non-sequence specific manner 20-24 nucleotides upstream of an exon-junction.  Functionally, the EJC aids in nuclear export of spliced mRNAs, assists in nonsense-mediated decay of incorrectly spliced mRNAs containing premature stop codons, and enhances translation efficiency.

Pre-mRNA bound by a spliceosome is usually not exported from the nucleus, so as to make sure that only fully-processed mRNA travels to the cytoplasm to be translated.  A protein called the mRNP exporter binds to the EJC, both through RNA interactions and interactions with the EJC-associated protein REF (RNA export factor) to help pre-mRNA exit the nuclear pore complex.

Interestingly, the efficiency of unspliced mRNA export is dependent on the length; longer mRNAs are exported more efficiently than shorter mRNAs. In spliced mRNAs, however, once the 5' exon is long enough to bind the EJC, the length of the spliced mRNA does not affect the export efficiency.

There are a certain number of EJCs in a cell, and they must be recycled in order to continue tagging mature mRNAs. Once in the cytoplasm, the ribosome-associated regulator protein (PYM) acts as a dissociation factor.
