How are the dna replication products visualized during the sanger method of dna sequencing?.
n200080 [17]

The DNA replication products visualized during the sanger method of DNA sequencing are observed in which nucleotides are added.

Sanger sequencing is based on the process of DNA replication. A scientist creates a copy of his DNA strand. Then observe which nucleotides have been added. This way you can see the sequence of nucleotides. A laser excites the fluorescent labels in each band and a computer detects the resulting light.

Sanger sequencing produces extension products of various lengths ending in dideoxynucleotides at the 3' ends. Extension products are separated by capillary electrophoresis or CE. Molecules are injected by an electric current into a long glass capillary filled with gel polymer. Selective incorporation of chain-terminating dideoxynucleotides by DNA polymerases during in vitro DNA replication.

What is the climate and weather information of freshwater wetlands
ziro4ka [17]

Answer:

The average temperature of a freshwater wetland in summer is 76 degrees Fahrenheit. The average temperature in winter is 30 degrees Fahrenheit. The climate in freshwater wetlands is usually semitropical, as freezing conditions rarely occur.

Explanation:

The most common freshwater wetland is swampland. The freshwater biome is located on every continent except for Antarctica. Most people think of it being a nuisance, but freshwater wetlands are an important part of our ecosystem. More examples of freshwater wetlands are marshes or bogs. In freshwater wetland the water will always be standing water. Most of them will have water in them all of the time, but some will only have water in them during certain parts of the year. There are 4 different seasons in freshwater wetlands. There is Summer, Fall, Winter, and Spring. The average temperature of a freshwater wetland in summer is 76 degrees Fahrenheit. The average temperature in winter is 30 degrees Fahrenheit. The average rainfall in a freshwater wetland is 59 inches or 150 centimeters to 200 inches or 500 centimeters. The freshwater wetlands get and average of 7-10 hours of sunlight a day throughout the year.

Plant cells have mitochondria, which use glucose to produce ATP. Where does the glucose originate?
Romashka [77]

Plant produces glucose in the chloroplast through the process of photosynthesis. Calvin cycle is basically the biological process through which glucose is produced. The steps involved are as follows:

1. Absorbed CO2 is added to RuBP and 6C sugar is formed.

2. Breaking of 6C sugar into two  3-phosphoglycerate molecules

3. ATP gives phosphate group  to form 3-phosphoglycerate which is later on converted into 1,3-biphosphoglycerate.

4. Electons are required by 1,3-biphosphoglycerate to an aldehyde called glyceraldehyde-3-phosphate or G3P and these electrons are donated by NADPH

5. Enzyme aldolase uses two molecules of G3P to produce 6 C sugar called  fructose-1,6-biphosphate which is further converted to fructose-6-phosphate

6. Enzyme  isomerase converts fructose-6-phosphate to glucose-1-phosphate
