The answer is All of the above
Answer:
- A large number of non-protein coding sequences are transcribed
- Total transcription changes over time in embryonic stem cells
Explanation:
The transcriptome refers to the totality of RNA molecules (i.e., mRNAs, microRNAs, long noncoding RNAs, etc.) that are synthesized in a given cell type/tissue/development stage. The analysis of human transcriptome has been essential to discover genes and non-coding RNAs expressed at each developmental stage, as well as genes whose expression is associated with human diseases. Next-Generation Sequencing (NGS) information showed that more than 90% of the human genome is transcribed into RNA, especially non-protein-coding sequences (i.e., non-coding RNAs). Moreover, information on the human transcriptome evidenced that global transcription changes occur in pluripotent embryonic stem cells, and these changes are mainly associated with the expression of chromatin-remodeling genes as well as genes responsible to encode the components of the general transcription machinery.
Answer:
Phospholipids serve as a major structural component of most biological membranes, e.g. cell membrane. The phospholipids are vital to the function of the cell membrane. Being amphipathic, their presence creates an effective barrier preventing the entry of all
