Answer:
The Amazon rainforest plays an important part in regulating the world's oxygen and carbon cycles. It produces roughly six percent of the world's oxygen and has long been thought to act as a carbon sink, meaning it readily absorbs large amounts of carbon dioxide from the atmosphere.
Answer:
I think it finishing weather
Answer: Fluorescence microscopy
Explanation:
A protein is substance that is the essential constituent of living cells because it forms part of its structure. T<u>hey are also found in plasma membrane</u>, where they assist substances to cross the membrane. Proteins can be:
- <u>Integral</u>: permanently attached within the plasma membrane.
- <u>Transmembrane</u>: it spans the entirety of the cell membrane.
- <u>Peripheral</u>: are only temporarily associated to the membrane.
Some integral proteins can act as cellular receptors. Other proteins are responsible for cell adhesion (binding of a cell to another cell or to a surface). On the outside of the cell membranes, attached to other proteins, are the carbohydrate chains that act as labels identifying the type of cell.
<u>A heterokaryon is a multinucleate cell and in this experiment the scientists fuse a human cell and a mouse cell, each of them will have their own proteins.</u> At first, the human and mouse proteins where found in separated halves of this heterokaryon. But <u>after a while, those proteins where mixed and could no longer be identified</u>.
A fluorescent chemical called a fluorophore is able to be absorb light of specific wavelengths and then emit light of longer wavelengths. The proteins can be modified and marked with different colored fluorophores to detect them, even if they are mixed in the heterokaryon. <u>Then, they can be seen with a Fluorescence microscopy, to identify them through different colors</u>.
Answer:
Since the 2 strands of DNA are antiparallel to on another, DNA must be replicated both continuously and dis-continuously. The side of DNA that is replicated dis-continuously is done so in small parts called <u>okazaki fragments</u>.
Explanation:
OKAZAKI FRAGMENTS - Okazaki fragments are short DNA nucleotide sequences (roughly 150 to 200 base pairs in eukaryotes) that are synthesized in a non-linear fashion and then linked together by the enzyme DNA ligase to form the lagging strand during DNA replication. They shape short double-stranded DNA sections when combined with the lagging template strand.
The primosome initiates Okazaki fragments by generating a new RNA primer. To restart DNA synthesis, the DNA clamp loader releases the lagging strand from the sliding clamp and reattaches the clamp to the new RNA primer. DNA polymerase III will then synthesize the segment of DNA.
Reiji Okazaki, Tsuneko Okazaki, and their colleagues first found Okazaki fragments in 1968 while researching bacteriophage DNA replication in E. coli.
Answer:
Mass Difference= Final Mass- Initial Mass
To find the “Percent Change in Mass,” divide the “Mass Difference” by the “Initial Mass.”
