Cells in onion peels are dead and the ones in spinach are alive.
The answer to your question is true :)
Answer: Similarities in amino acid sequence strongly suggest common ancestry
Explanation:
The chemical make-up and biochemical process of all organisms are as very similar. For example, all organisms
- are build up of the same types of complex molecules such as carbohydrates, lipids, proteins (polymers of amino acids) and nucleic acids
This similarity strongly suggest common ancestry for all organisms, thus leading to evolution of individual species
In a plant species, if the b allele (blue flowers) and the b allele (white flowers) are incompletely dominant (bb is light blue), an all light blue offspring<span> ratio is expected in a cross between a blue-flowered plant and a white-flowered plant.</span>
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.
