A linear shaped piece of DNA strand is obtained when a plasmid is cut HindIII, Apa1, and Sma1.
Explanation:
Restriction enzymes are endonucleases which enzymatic proteins which can cut a DNA at specific sequences at particular recognition sites. The sequences recognized by these enzymes are usually palindromic that occurs for a definite length (6 bp, 4 bp, or 8 bp).
They can either be blunt cutters or sticky end cutters. APA1, SMA1, and HindIII are all restriction enzymes which can cut a circular plasmid at specific locations.
These restriction enzymes bind with the DNA at specific locations and cuts them to give linear strands of DNA either with a blunt or a sticky end.
The choices can be found elsewhere and as follows:
A. mature leaves
B. shoot apical meristem
C. cell elongation zone
<span>D. axillary buds
</span>
I think the correct answers are option B and D. It would be at the shoot apical meristem and the axillary buds that <span> a vascular plant would you expect to find totipotent cells. Hope this answers the question.</span>
Answer:
They are used as an indicator organism for pathogenic bacteria.
Explanation:
Coliforms are bacteria found in digestive tract of animals and humans. They are non-pathogenic, easy to culture and are used as an alternative indirect testing for presence of other microorganisms. Coliforms thrive in exact environmental conditions like other pathogenic bacteria, thus often used to indicate whether they are bacteria found in drinking water and swimming pools that might end up causing infections.
Therefore the existence of coliforms in water easily indicates feacal contamination.
Answer:
If the trait for tall and trait for yellow are recessive: ttyy and ttyy
If the trait for tall is dominant and trait for yellow is recessive: TTyy and TTyy, Ttyy and TTyy
If the trait for tall is recessive and trait for yellow is dominant: ttYY and ttYY, or TtYy and TTYY
If the trait for tall is dominant and trait for yellow is dominant TTYY and TTYY, or TtYy and TTYY
