Each (细胞) of our bodies contains 46 chromosomes.相关知识点: 试题来源: 解析 cell 本题考查名词用法。①句意分析。“我们人体的每个细胞都包含46个染色体。”②词性判断。挖空处位于动词contain前,且跟在代词each后。判断为名词。③解题要点。cell即为“细胞”。根据each后跟单数名词,所以cell正确。
Cells produced by meiosis have the diploid number of chromosomes. True False Spermatogonia and a 1 oocyte are both diploid (46 chromosomes). a. True b. False Answer true or false: If gametes were produced by mitosis instead of meiosis, zygotes would contain twice the diploid number, and...
Within eukaryotic cells, DNA is organized into long structures called chromosomes. Before typical cell division, these chromosomes are duplicated in the process of DNA replication, providing a complete set of chromosomes for each daughter cell. Eukaryotic organisms (animals, plants, fungi and protists...
A chemical amplification resist composition contains: (A) a polymer compound having a phenolic hydroxyl group and a group formed by substituting a substituent for a hydrogen atom of a hydroxyl group in a phenolic hydroxyl group and satisfying the following (a) to (c) at the same time: (a)...
Another level of regulation involves alterations in the subunit composition of these multi-subunit complexes. The mammalian cells contain BAF and PBAF complexes. BAF complex can contain either BRG1 or BRM as the ATPase subunit, while PBAF complex contains only BRG112,13. Further, the subunit ...
These observations might imply that the ground state is the absence of sternopleural bristles and that Scr and Ubx simply act to return the state to the ground state by repressing Antp expression. However, the occurrence of sternopleural bristle formation by cells lacking Antp activity suggested ...
assuring a thorough and sensitive detection of the widest array of metabolically-involved bacteria, in case the massive amount of 16-rRNAs produced by the most active cells would mask the less active ones. Nonetheless the protocol is equally suited to perform in any other sequencing platform, as...
microtubules than the Y kinetochore, likely explaining the alignment of the sex trivalent at the spindle equator with autosomes. These observations inR. megaerasupport the evolutionary significance of the metaphase alignment of chromosomes and provide part of the explanation for how this alignment is ...
