Answer: Purine; is equal to; pyrimidine
Explanation:
When a segment of DNA is examined then the nucleotide in one DNA molecule, it will be expected that the sum of purine in one strand will be equal to the sum of the pyrimidine in the other strand.
Adenine combines with Thymine and Cytosine combines with Guanine in 1:1 ratio.
More specifically the ratio of purine is to pyramidine is 1:1 in an organism. This pattern is seen in both the strands of the DNA.
The correct answer is A. Bases pairs, DNA, Gene, Chromosome, Cell.
Explanation
Nitrogen bases are chemical compounds that compose DNA and RNA, in the case of DNA the bases are adenine, thymine, guanine, and cytosine, while RNA is made up of uracil, adenine, guanine, and cytosine. Additionally, DNA makes up genes, which are structures that store information that is passed on to offspring. Also, genes are organized to form chromosomes (more complex structures) of genetic information. Finally, there are cells, in them are chromosomes, fundamental for the reproduction of an organism. Therefore, the correct answer is A. Bases pairs, DNA, Gene, Chromosome, Cell.
Answer:
C
Explanation:
D in my opinion wouldn't be correct because a vaccine is for if you come in contact with the sickness you are more protected and helps build immunity. So healthy people get them to try and build immunity against said vaccine. Like if you have the flu, your body is fighting. In the Flu vaccine parts of the flu are in the vaccine to help your body learn to become immune. So option C.
Sorry if this is confusing, hope it helps!
Answer:
Hydrogen bond
Explanation:
<h3>The covalent bonds between the oxygen and the hydrogen atoms result from a sharing of the electrons. This is what holds the water molecules themselves together. The hydrogen bond is the chemical bond between the water molecules that holds the mass of molecules together.</h3><h3>hope the answer was helpful, mention me as brainliest.</h3><h3 />
Answer: All the statement are correct.
Explanation:
In prokaryotes, an operon are unit of transcription regulation, operon are functioning unit of DNA of which consists of cluster of related genes with a single promoter and an operator.
The structural genes in the operon are either all ON or OFF at the same time, because they are controlled by a single promoter and an operator. Represible or inducible operon are all turned of off unless needed.
The DNA of an operon are generally transcribed into a single mRNA molecule which is polycistronic that codes for more than one protein
