Sequencing with devices such as the minion can be used to study individual organisms. however, researchers sometimes also study the genetics of an entire community in an environmental sample (metagenomics) without distinguishing individual organisms. why would researchers study the metagenome of an entire community in this way rather than separating out individual species

25) a student takes four samples of a white crystalline solid and places each in a well plate. on top of each sample, she carefully places 20 drops of clear mystery liquids a, b, c and d. her results for each well are: liquid a: the solid dissolves quickly. liquid b: the solid appears unchanged. liquid c: a brownish colored liquid is produced. liquid d: fizzing occurs and the well becomes warmer. in which well does a physical change occur?

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.

Mitosis creates two identical daughter cells from one parent cell creates four nonidentical daughter cells from one parent cell is the most common type of reproduction for bacteria is the process by which male and female reproductive cells are created
