There are microbes that live in very hot places. They have been found in hot springs and in underwater volcanoes. Other microbes live in very cold places, like Antarctica. Some microbes can even survive being frozen at tempuratures as low as -80 degrees Celsius. ...
Single-cell marine organisms referred to as 'foraminifera' as mentioned in the text might serve as ___ A. a proof against the existence of oxygen-16. B. a testimony to sediment formation processes. C. a valid record justifying glacial periodic cycles. D. an indicator of the ratio of the...
Ion channels are located in the membranes of cells and regulate how charged particles called ions move in and out of the cell, a process that results in the electrical signals that are the foundation of communication in the nervous system. The Shaker family of ion channe...
英语翻译The earliest organisms,single-celled creatures called prokaryotes,which include bacteria,probably did not age but rather divided damaged material equally among new cells.There was not a parent cell,but rather the original cell divided int
BEIJING, Jan. 8 (Xinhua) -- Chinese experts have published a single cell spatio-temporal map of human limb development, shedding light on the cell evolution path and the determination process of cell spatial position in fetal limbs. Human limbs emerge during the fourth post-conception week as ...
Noisy gene expression is of fundamental importance to single cells, and is therefore widely studied in single-celled organisms. Extending these studies to multicellular organisms is challenging since their cells are generally not isolated, but individuals in a tissue. Cell–cell coupling via signalling...
These sponges co-existed with an enigmatic extinct group of large flat marine organisms called "Ediacaran fossils" that may have been ancestral to modern animal groups but might also have been a failed attempt at complex multicellular evolution....
Metagenomics and single-cell genomics are powerful cultiva- tion-independent approaches for probing the nature of so-called 'dark matter' organisms by facilitating access to their genomes5,6. Although metagenomics has allowed the recovery of partial or nearly complete genomes from several candidate ...
Single-cell transcriptome sequencing (scRNA-seq) has been employed to define cellular subtypes by revealing their specific transcriptional signatures. Compared with so-called ‘bulk RNA-seq’ studies of whole organisms or tissues, scRNA-seq has exceptional resolving power, being able to detect genes ...
The hybrid sequencing and analysis approach used here can be applied to other tissues and organisms to identify intact transcripts and novel isoforms. The functional enrichment of spiRNAs encoding for the protein components of ribosomes suggests a possible role for these transcripts. There are no ...
