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)...
Answer:
To survive. Drinking is very important and is required for animals and organisms to survive. It also keeps us hydrated.
Explanation:
Respiration is the type of biological exercise that raises Co₂ concentration in the atmosphere.
Explanation:
RESPIRATION is said to be the basic biological and metabolic process that is essential for all living beings for their survival and growth with nourishment.
Cells are the basic unit of living organisms that undergo cellular respiration. In this process, oxygen is in taken and carbon dioxide is respired out which adds the concentration of the carbon dioxide from the atmosphere.
In the process of respiration, the living cells of the organism produce energy by the intake of oxygen for the oxidation of complex organic substances and expires out the carbon dioxide.
Answer:
True
Explanation:
The mesentery fans throughout the abdomen. It is attached to the abdominal wall and the intestines, to keep them in place. It also prevents the intestines from falling down or twisting inside the abdomen. They also help with fighting infection as they have lymph nodes as well.
