Which procedure would help ensure that a new piece of DNA can be inserted inside a bacterial plasmid when the two are mixed toge
Elodia [21]

Answer:

The fragment and plasmid are both cut with the same restriction enzyme.

Explanation:

To insert a piece of DNA in a bacterial plasmid, we need to cut both plasmid and DNA insert from same regions. This is typically done by restriction enzymes or restriction endonuclease. This cutting will open the plasmid (which is circular initially) and produce <u>sticky ends.</u> Here, DNA insert can attach because of similar sequence (see attached figure). In the final step, DNA ligase will glue it in the plasmid and it will become its part. This technique has been extensively used as a DNA recombinant technology. A better representation can be seen in the attached figure where both DNA sequence of interest and plasmid are cut with the same restriction enzyme (shown as scissors) and then ligated with DNA ligase.

What are transport proteins and how do they work
Afina-wow [57]

Transport proteins move objects and materials into and out of the cell that are either too large, or too polar to cross the membrane on their own. This process is also passive by the way - meaning no ATP is required.

Which of the followings statements is true about cones?a. All of these statements are true.b. They are found in the fovea.c. The
levacccp [35]

Answer:

a. All of these statements are true

Explanation:

The fovea is a region of the retina that’s densely packed with cones, a type of photoreceptor (a cell that detects light). The other type of photoreceptor is the rod.  

While <u>rods function at low light levels</u> and allow night vision, they can’t distinguish color. In contrast, <u>cones function at high light levels and provide color vision</u>.  

That's why you can't perfectly distinguish colors in a dark place.
