Introns are parts of genes that do not directly code for proteins. (2)
Exons are parts of DNA that are converted into mature messenger RNA (mRNA). (6) The process by which DNA is used as a template to create mRNA is called transcription.
Answer:
The correct answer is c. cell fractionation
Explanation:
Cell fractionation is the technique which allows different cells part to be separated from each other on the basis of their density gradient by using a centrifuge.
In cell fractionation, first the cell wall and membrane of cells are broken by chemical, physical or mechanical method. Then the cell component can be separated by centrifuging them at different rpm.
Components that have higher density can be found in the bottom and the light density can be found on top of the tube. Therefore the correct answer is c. cell fractionation.
Well people use the scientific method everyday in their jobs
Lets take a Culinary professional first when they want to make a new recipe they must first
Question what Ingredients might go well together
They then do research (Be if it is asking opinions)
They conduct a hypothesis
They then test it by making it
Then they collect data (Having people taste it)
Hope this Helped...
Communicate results of the Recipe
Answer:
Explanation:
They discovered that the difference between lactose tolerant/persistence and intolerant individuals was due to a mutation located in another neighbouring gene that controls its persistence.
This gene is the MCM6 gene. This gene affects lactase promoter activity likely causing lactase persistence. It is located in a regulatory region upstream of the lactase (LCT) gene.
Answer:
a. 40%
Explanation:
up to 40% increasing the light intensity increases the oxygen production. Beyond 40% there is no effect.
