Assume that a given plasmid vector to be used in a cloning experiment contains 4000 base pairs of DNA. Assume also that the rest

riction endonuclease Cuj cuts this plasmid at the following sites (starting from an arbitrary zero point): 1000, 1500, and 3000. Given complete digestion of the plasmid with the endonuclease so that only linear fragments are produced, what sizes of DNA are expected?

Answer:

1000, 2000 and 3000.

Explanation:

The example given in the question is of a DNA with 4000 base pairs and it is being cut at 1000 pairs, 1500 pairs and 3000 pairs. So the lenghts of the segments that are cut from the original spiral are 1000, 500, 1500 and 1000 respectively. And the information that only the linear fragments are being produced is given to us in the question so the sizes of DNA expected would be 2000, 1000, 3000 and 2000 again respectively.

I hope this answer helps.

Answer:

Explanation:

1. Latitude or distance from the equator – Temperatures drop the further an area is from the equator due to the curvature of the earth. In areas closer to the poles, sunlight has a larger area of atmosphere to pass through and the sun is at a lower angle in the sky.

2. Altitude or height (also sometimes known as depth) is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Although the term altitude is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage.

3. Large bodies of water, such as oceans, seas and large lakes, can affect the climate of an area. Water heats and cools more slowly than landmasses. Therefore, the coastal regions will stay cooler in summer and warmer in winter, thus creating a more moderate climate with a narrower temperature range.

4. Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean

What type of weather does a H pressure system bring to an area? *
Dmitriy789 [7]
<h2>Answer:</h2>

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

   

<h3>✅ Clear skies and Sunny.</h3>

<h2>Explanation: </h2>
  • ❗ Cold air is denser and thicker than warm air, so it usually sinks as warm air increases. Cold air sinks which causes a transient accumulation of water near the earth's area and thus an area with a high pressure in regions where winds meet at high altitude. With an increase in altitude air pressure reduces, so high pressure is in fact a relative concept. Weather forecasters commonly use this to signify high pressure relative to normal atmospheric pressures at that level.

Upon exposure to blue light, plants not only begin to grow toward the light, but move their chloroplasts to the sunny side of ea
Ne4ueva [31]

Answer:

A) maximizes light absorption by the chloroplasts for photosynthesis

Explanation:

Chloroplasts are the double membrane-bound organelles present in the leaf cells. Chloroplasts contain light-absorbing pigment chlorophyll that absorbs maximum light of blue and red wavelengths.

Absorption of light by chlorophyll pigments drives the light reactions of photosynthesis which in turn provide ATP and NADPH to fix carbon dioxide gas into glucose by light-independent reactions. The process of photosynthesis produces glucose which in turn serves as an energy source for plants and supports their growth and development.

Therefore, exposure to blue light increases the rate of photosynthesis as chloroplasts in the leaf cells are aligned to absorb maximum blue light to support photosynthesis. And a higher rate of photosynthesis produces more glucose to support the growth of the plants.

Why does a frameshift mutation usually cause more effects during protien sythesis than a point mutation
Levart [38]

Frameshift mutation affects codons downstream the point of mutation. The previous order of 3 nucleotide- sequences (codons) is consequently changed. This, therefore, changes the protein coded by the mRNA transcribed by the mutated DNA region. Frameshifts are mostly due to insertion or deletion mutations.
