Answer: The steps are made of nitrogenous bases; deoxyribose sugars linked with phosphates.
Explanation: The rungs of the DNA are made of nitogenous bases (The nitrogenous bases are adenine (A), thymine (T), guanine (G) and cytosine (C) ) they are held together by weak hydrogen bonds.
The railings of the DNA are made of deoxyribose sugars which are alternating with phosphates. This part of the molecule is referred to as the "backbone".
Answer: Venus, Mercury and Mars are the differentiated planets.
Planetary differentiation can be defined as the process by which the separation of different types of constituents takes place. They are differentiated on the basis of their chemical or physical behavior.The denser material of the planets sink to the center of the planet and the less denser particles rise at the surface of the planet.
Bird
Condensation
The bird flys through a cloud and the cloud is condensation
Answer:
the earths layers are troposphere and stratospher while the atmospheric is the mesosphere
Explanation:
Question: Please use the following information to answer the question(s) below. A group of six students has taken samples of their own cheek cells, purified the DNA, and used a restriction enzyme known to cut at zero, one, or two sites in a particular gene of interest.
Analysis of the data obtained shows that two students each have two fragments, two students each have three fragments, and two students each have one only. What does this demonstrate?
Answer:
"The two students who have two fragments have one restriction site in this region."
Explanation:
A restriction enzyme, restriction endonuclease, or restrictase is an enzyme that cuts DNA into trashes at or close precise appreciation sites inside particles identified as restriction locations. Restriction enzymes are one session of the wider endonuclease collection of enzymes. In the laboratory, restriction enzymes (or restriction endonucleases) are used to cut DNA into minor trashes. The scratches are constantly made at exact nucleotide arrangements. Unlike restriction enzymes recognise and cut diverse DNA sequences.
