without making any other adjustments the _____ can be increased by focusing properly.

Answers

Resolution is the ability that a microscope has to distinguish fine details. Without making any other adjustments the RESOLUTION can be increased by focusing properly in a brightfield microscope.

A brightfield microscope (also called compound light microscope) is a light microscope that produces dark images against a bright background.

The brightfield microscope is widely used in cellular biology and microbiological laboratories.

The resolution of the brightfield microscope is limited to 0.2 micrometers (µm).

This maximum value can be reached by changing the objective lens.

in yeast that has been genetically modified to be able to produce spider silk, the ________ is joined with the ________ .

Answers

A transgenic organism is an organism whose genome (DNA) has been altered by recombinant genetic engineering techniques. These techniques can be used to transfer exogenous genes within transgenic species.

In yeast that has been genetically modified to be able to produce spider silk, the spider silk CODING SEQUENCE is joined with the yeast REGULATORY SEQUENCE.

In this case, transgenic yeast has the spider silk coding gene sequence (i.e., the exons) that encodes for the spider silk protein, whereas a regulatory gene sequence (e.g., a promoter gene sequence) from yeast have been preserved in order to regulate the expression of the target exogenous gene.

The most important genetic engineering techniques used to create transgenic animals include DNA microinjection and retrovirus-mediated gene transfer.

The structural elements of a virus, such as the capsid, envelope, and spike proteins, serve to protect and deliver the viral genome into host cells for replication.

What are the structural elements of a virus?

The structural elements of a virus have different functions that are essential for the survival and replication of the virus. These elements include:

Capsid: The capsid is the protein shell that surrounds the viral genetic material. It provides protection to the viral genome and determines the shape and size of the virus.

Envelope: Some viruses are surrounded by an envelope, which is a lipid membrane that covers the capsid. The envelope helps the virus to evade the host's immune system and enter the host cell.

Spike proteins: Spike proteins are protruding structures on the surface of the envelope that are used to bind to the host cell. They play a crucial role in the process of virus entry into the host cell.

Nucleocapsid: The nucleocapsid is the complex of the viral genome and the capsid. It is responsible for protecting and delivering the viral genetic material into the host cell.

Tail fibers: Some viruses have tail fibers, which are structures that help the virus to attach to the host cell and initiate the entry process.
