How the DNA is different from the cDNA?
Alexandra [31]

Answer:

gDNA = "genomic DNA" and cDNA = "complementary DNA." cDNA is classically associated with being reverse transcribed either from all extracted RNA from a tissue or cell (total RNA) including (in eukaryotes) pre-mRNA, ribosomal RNA, tRNA, snoRNA, miRNA and mRNA, etc.) while cDNA obtained only from reverse transcription of the mRNA (expressed eukaryotic cytosolic mRNA) fraction (e.g., by poly[dT]n and random priming) is complementary DNA (cDNA) made from what is called the "transcriptome." Eukaryotes have introns and exons in the gDNA, while prokaryotes do not. So eukaryotic cDNA reverse transcribed from mRNA lacks introns. Prokaryotic-derived cDNA is always complementary to prokaryotic RNA and gDNA (so is always necessary to have a good DNase treatment prior to gene expression analysis by e.g., qPCR for prokaryotic transcriptome work)...

Which best explains mantel convection
Snowcat [4.5K]

Answer:

The heat given off by Earth's core is circulated through mantle convection.

Explanation:

Heating materials usually causes them to <em>expand</em>; as they become hotter, they also become less dense. Convection describes the transfer of heat from hot areas of liquids and gases to cooler ones. This causes the heated, less dense material to rise and more dense material to fall, as it’s pulled by gravity. Super-heated metal forming Earth’s central core heats rock in the mantle; the hot and cool rock slowly rise and sink- this circulation process is called mantle convection.
