g DNA sequences that are deduced by comparing many related DNA sequences are called . [ Choose ] Unlike DNA synthesis, RNA synthesis requires . [ Choose ] direct RNA polymerase to the initiation site.

consensus sequences; no primer; promoters

Explanation:

In bioinformatics, consensus sequences refer to sequences (i.e. DNA, RNA, or amino acids) that represent aligned related sequences (usually evolutionarily conserved sequences). In DNA, consensus sequences may evidence putative DNA binding sites. Transcription refers to the process of RNA synthesis by using as a template a DNA sequence. The start of DNA synthesis requires a primer (i.e. a short oligonucleotide sequence with an available hydroxyl group on the pentose sugar), whereas RNA synthesis requires no primer. Finally, promoters are DNA sequences that determine the site in which transcription of a gene by the RNA Polymerase begins. Promoter sequences are located near the transcription start site (TSS) at the 5'-end of a gene sequence, and range in size from 100 to 1000 base pairs (bp).

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
