Answer:
The statement suggests ability of existing DNA molecule to replicate itself by the process of DNA replication. Each strand of double helical DNA can serve as template for the synthesis of new complementary DNA strand.
Explanation:
Watson and Crick proposed the double-helical structure of DNA. Accordingly, the DNA molecule is a double helical structure in which two polynucleotide chains are held together by base pairing between the complementary bases of two chains.
There are four nitrogenous bases present in DNA: adenine and guanine (purines) and cytosine and thymine (pyrimidines). Adenine always pairs with thymine and cytosine pairs with guanine base.
According to Watson and Crick, the ability of one DNA strand to base-pair with a complementary DNA strand suggests the existence of the DNA replication process. During DNA replication, each DNA strand should serve as a template to specify the nucleotide sequence of the new DNA strand.
Answer:
Subscript
Explanation:
The small numbers below the line are subscripts (Latin <em>sub </em>+<em> script</em> = under + written).
One of the RNA molecules formed during the first initial stage of protein synthesis, called transcription, in eukaryotes is mRNA or messenger RNA.
Answer:
They suffered a stroke. (Ans. B)
Explanation:
Stroke is known as the medical situation that damages the brain from the termination of its blood supply. Stroke symptoms involve trouble in speaking, paralysis of the face, leg, and arm, muscle weakness, sudden vision loss, etc.
Initial treatment given to the patient with medication like clot-buster, it helps to minimize brain damage. Other medications help to prevent complications and avoiding extra strokes. If Mr. Pappadopolis does not shave the left side of his face or button his left shirt cuff than he is surfing from paralysis stroke of the left side of the body.
