MRNA is made from a DNA template, and DNA is double-stranded. During transcription, the "template strand" is the DNA strand that is the complement of the mRNA. The "coding strand" is the DNA strand that has the same sequence (DNA ATTGC would be RNA AUUGC) as the mRNA transcript.
A gamete will have exactly half the number of chromosome ,that is haploid,therefore ,19
Developed Calculus -

Who developed a model of the universe with the Sun at the center
<u><em>Nicolai Copernicus
</em></u>
The Earth-centered Universe of Aristotle and Ptolemy held sway on Western thinking for almost 2000 years. Then, in the 16th century a "new" (but remember Aristarchus) idea was proposed by the Polish astronomer Nicolai Copernicus (1473-1543).
The answer is D. Nitrogen & Oxygen
Answer:
<h2>D. Radioactive nitrogen in the DNA of the bacterial cells is present in one strand of the DNA of all of the cells.</h2>
Explanation:
As given here,
The nitrogenous base of DNA is radio active labeled, and is grown in normal unlabeled medium.
As we know that DNA replication occurs in semi-conservative way, so after one round of replication, one parental strand would be radio active and other newly synthesized strand would be unlabeled.
So here, after one round of replication, one strand of all the newly synthesized DNA would be radio active and other strand would be normal.
