Answer:
The proportions of nucleotides in the newly formed complimentary strand will be:
14% Thymine (T), 33% Adenine (A), 21% Guanine (G), 32% Cytosine (C).
Explanation:
In a double stranded DNA, the nucleotides of one strand binds with nucleotides of another strand through hydrogen bonds.
Adenine binds with thymine by two hydrogen bonds (A=T) and guanine binds with cytosine by three hydrogen bonds (G≡C).
So, the complimentary strand must have
- thymine equal to the amount of adenine in template strand.
- adenine equal to the amount of thymine in template strand.
- guanine equal to the amount of cytosine in template strand.
- cytosine equal to the amount of guanine in template strand.
Answer:
Food chain shows only one part of animal and the food they consist of while food web shows different animals and different type of food they eat. Food chain is part of food web
A tectonic plates
Because the outermost part of earth is know as the lithosphere. The lithosphere is divided into a number of tectonic plates. These plates move and interact with one another, driven by conventional forces within the earth
Answer:
B. 18
Explanation:
An atom, which is the smallest indivisible particle of matter, further contains certain particles called SUB-ATOMIC PARTICLES namely: proton, neutron and electron. In a neutral/uncharged atom, the number of proton is equal to the number of electrons. The number of protons in an atom represent its ATOMIC NUMBER.
However, the sum of the proton number and neutron number gives the MASS NUMBER i.e. mass no. = proton no. + electron no.
Hence, according to this question which states that an atom has an atomic number of 17 and a mass number of 35. The neutron no. can be calculated as follows:
Neutron no. = mass no. - proton no.
Neutron no. = 35 - 17
Neutron no. = 18
