Answer:
Transcription is the second step in central dogma of molecular biology. First step is replication, second is transcription, and third is translation.
In the transcription phase, DNA, which is already replicated, is transcribed to mRNA which is required to make proteins in the translation phase. The root words say it is a combination of "across" and "write". This means that DNA is going to be written in a new language "mRNA". So, this term has been used in biological process because it is the re-writing across the whole DNA to make a completely new strand of mRNA.
Hope it helps.
Answer:
1981
Explanation:
<em>"A new era in space flight began on April 12, 1981, when Space Shuttle Columbia, or STS-1, soared into orbit from NASA's Kennedy Space Center in Florida."</em>
A. DNA material coiled up in a pile.
The theory of tectonic plates explains that large convectional currents occuring in the mantle(as a result of magma) are the reasons plates,and so continents,are moved. Note movement occurs in the boundary in between the plates.
Answer: Option B) No, even though the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.
Explanation:
Since the triplet codon ACG codes for the amino acid threonine, so also ACA codes for threonine, the single base change of Guanine (in ACG) to Adenine (ACA) is insignificant due to the degeneracy of the genetic code.
Thus, the sequence still codes for the same amino acid, so no change in phenotype will occur
