Answer:
To produce a terminator nucleotide in Sanger DNA sequencing, a(n)<u> oxygen </u>atom is removed from the hydroxyl group on the deoxyribose sugar where it bonds with the adjacent phosphate group
Explanation:
DNA consists of a double helix made up of nucleotides.These nucleotides are arranged in such a way that each nucleotide has a phosphate group , a sugar and a nitrogenous base.
Sanger sequencing is a method of DNA sequencing which is actually based on the selective incorporation of the chain-terminating dideoxynucleotides by DNA polymerase during the DNA replication
The Sanger sequencing has following steps :
1) denature dsDNA using heat.
2) Make multiple copies of a segment.
3) Attach a primer.
4) Add to four polymerase solutions.
5) Grow complementary chains until termination dye.
6) Denature the grown chains.
7) Electrophorese the four solutions.
A swamp is an area of a land that is permanently filled with water. It could be formed out from a former lake or pond overtaken by trees. It is also dominated by trees. Cypress and tupelo trees, bushes and shrubs grow in swamps and even tiny plants like the duckweed that almost covers the water surface.
A river is a large area where water flows to the ocean, the lake, etc. and its seawater consistently evaporates. Its source could be from a melting snow, a melting glacier, a lake with an out-flowing stream or a spring bubbling out of the ground.
Two reasons for the difference:
1. Swamps have many formed marine animals and insects while the river, you can only rarely find one (like fishes).
2. Rivers could be a source of water into houses, farms and even a drinking water for humans while swamps could not be a source for those.
Answer:
D(Movement
Explanation:
The integumentary system, which includes the skin, protects the body and regulates temperature/homeostasis. It also eliminates small amounts of waste, but it does not aid in movement directly.
True, though the Hadean period is one exception.
A)
Therefore:Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote).
b)
Therefore:Crossing results in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).
c)
Therefore:Crossing results in 100% (homozygous recessive).
