This is false. DNA transcription is the first step in gene expression.
The example of a biotic factor is the shrimp population in a bay. Biotic factors are living factors that affect organisms in an ecosystem. The biotic factors includes the producers or autotrophs, consumers or heterotrophs, and decomposer. Abiotic factors on the other hand are the non-living factors that influence an ecosystem; they include, sunlight, soil, humidity, etc
Answer:
Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through. Extensive blood supply - ensuring oxygen rich blood is taken away from the lungs and carbon dioxide rich blood is taken to the lungs.
Answer:
The climate is getting warmer so all the ice caps and other cold laces on earth with ice are melting therefore the sea levels are rising

The researchers prepare an intron-free copy of the eukaryotic gene for the use in creating the transgenic bacteria by using the reverse transcriptase to make the cDNA from the mature mRNA
The structure of the eukaryotic genes. Most of the eukaryotic genes are contain the segments of the coding sequences (exons) that interrupted by the noncoding sequences (introns). Both the exons and the introns are transcribed to yield a long and primary RNA transcript.
Eukaryotic DNA is the linear, compacted into the chromosomes by the histones, and has the telomeres at each end to protect from the deterioration. The Prokaryotes contain the circular DNA in addition to the smaller, transferable DNA plasmids. Eukaryotic cells contain the mitochondrial DNA in the addition to the nuclear DNA
