qaws [65]

The restriction endonuclease EcoRI cleaves the DNA sequence 5'-GAATTC-3' in such a way as to leave a 5' overhang, which is often referred to as a "sticky end". To 5' overhang with the complementary sequence this sticky end adhere.

  • The palindrome EcoRI restriction site breaks DNA after G and creates sticky ends with AATT. G/corresponding AATTC's DNA sequence is CTTAA/G, where "/" designates the location of the peptide bond break.
  • When the ssDNA sequence 5'-GAATTC'-3 is recognised by the restriction endonuclease EcoRI, a single-strand cut is made between the G and A nucleotides.
  • At the ultimate end of double-stranded DNA, an overhang is single-stranded DNA. This can occur on either strand, and if it does, there will either be a 5' overhang on the 5' end of the strand or a 3' overhang on the 3' end of the strand.

The region of the transcript from the 5’ cap to the nucleode just upstream of the start codon is called the 5’ untranslated regi
nignag [31]

In prokaryotes the 5' UTR is 3-10 nucleotides.

In Eukaryotes the 5'UTR is 100 to many thousand nucleotides long.

Explanation:

Leader sequence or 5' UTR starts at transcription site and ends at the initiation codon just one nucleotide away from it.

It is present in mRNA.

These are GC rich and form secondary structure, helps in protein synthesis.

Shine Dalgarno sequence in prokaryotes is an example of 5'UTR.

It acts as an entry point of ribosome.

1. Compare the average global temperatures from the early 1900’s and the early 2000’s. How has the
sveticcg [70]

1. The average global temperatures from the 2000’s early are higher than those from the early 1900’s. We can see from the diagram that the average global temperature in the 1900s was about 57 degrees Fahrenheit (13.8 o C). In the 2000s the temperature raised to more than 58 F (about 14.5 o C). The world temperature is increasing due to human activity or natural variability. Some of the causes of this global warming are:  burning of fossil fuels, agriculture , deforestation all leading to greenhouse effect.

2. Carbon dioxide (CO2) is naturally present in the atmosphere as part of the carbon cycle, but its amount is raised due to human activities. This gas is produced by the process of burning fossil fuels (coal, natural gas, and oil), solid waste, trees and wood products..CO2 is removed from the air by the absorption of the plants or it dissolves into the ocean over a period of 20–200 years.

Methane is produced during the production and transport of coal, natural gas, and oil. It is removed from the atmosphere by chemical reaction, persisting for about 12 years.

Nitrous Oxide (N2O) is formed during agricultural and industrial activities or during the burning of fossil fuels and solid waste.N2O is destroyed in the stratosphere persisting for around 114 years.

Fluorinated gases such as hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride are formed in different industrial processes. Those gases have long atmospheric lifetimes sometimes thousands of years.

3. Greenhouse gases such as CO2, N2O, fluorinated gases, methane are gases that trap the heat in the atmosphere, causing the warmer climate. The amount of a particular greenhouse gas in the atmosphere can be measured. Higher emissions of those gases lead to higher concentrations in the atmosphere. Because of the Industrial Revolution , atmospheric greenhouse gas amount is raised for the last century and that increased the global average temperature.

4. There are many ways for reducing the amount of CO2. Some of them are:

• Reduce Vehicle Emissions, since the use of vehicle for transport is one of the largest sources of this greenhouse gas. Drive a bike, get a gas-efficient vehicle or a hybrid car.

• Reduce Home Energy Carbon Emissions by insulating and sealing your home, turning off lights, add solar panels to the roof of your home etc.

5. Solar energy that travels to the Earth is absorbed by the its surface and converted into heat, which is released into the atmosphere. The greenhouse gases such as carbon dioxide (CO2) absorb that heat and send it back to the Earth's surface. This process is known as the greenhouse effect and it leads to temperature increase. This happens because the increase in greenhouse gases in the atmosphere trap too much heat.  

6. Since the greenhouse gases trap the heat, if there were less of those gases, much of the infrared radiation (solar  energy) that is converted to heat today would not be trapped in the Earth's atmosphere. The  temperature of the Earth would cool down, and a conditions of the Ice Age would occur. These conditions would be very unfavorable for plants and animals, oceans would freeze, and weather patterns would change.

What happens to the Atoms when water turns ice
yulyashka [42]

Molecules are moving because they have energy. As the liquid cools down, the amount of energy is reduced and the molecules start to move slower. When the water temperature reaches around 0°C, the molecules stick together and form a solid – ice. Even in this solid stage, the molecules are still moving – we just can’t see it.

Some donor centers have implemented the practice of diverting the first few milliliters of blood collected into a pouch attached
Stolb23 [73]

Answer:

To prevent or limit bacterial contamination of the collected blood

Explanation:

The first few milliliters of blood have been reported to have a high probability of bacterial contaminant from the skin. Several studies have shown that diverting the first 10 to 30 milliliters of blood from a donor into a special pouch is effective in limiting the chances of collected blood being contaminated with bacteria.

<em>Hence, the purpose of the procedure is to limit the bacterial contaminant that will enter the blood collection bag.</em>
