1. The author believes that the challenges presented might be solved through growing of algae in enclosed bioreactors (even though bioreactors are expensive), the involvement by big-league investors and oil giants and with clear understanding of the yield algae will produce.

2. The challenges the author described in this article are:

i. The challenge of looking for the right algae strains/species that can give high yields.

ii. The challenge of protecting from contamination.

iii. The challenge of building cost-effective chambers.

iv. The challenge of harvesting the oil effectively.

Below is an evidence from the excerpt:

Challenges include finding strains of algae that reliably produce high yields, keeping contamination at bay, developing cost-effective growth chambers and efficiently harvesting oil from the cells."

Explanation:

"Gold Rush Of Algae" gives a clear insight into the importance of algae. This excerpt reveals the economic benefits of algae and the prevalent issues and challenges surrounding the cultivation of algae. The author gives some advice on how to deal with the challenges.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
