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。反馈 收藏
Our bodies are made of many different parts and functions. Each of these parts has a particular job that enables to body to function properly and thrive, even when conditions change. This also includes chromosomes.Answer and Explanation:
Identify whether each of these human cells are haploid or diploid. a. brain cells b. sperm cells c. red blood cells d. egg cells Ploidy: Ploidy is the number of complete sets of chromosomes within a cell. A cell that is haploid has...
Humans have 23 pairs of chromosomes. During mitotic cell division, sister chromatids get separated to opposite sides of the cell (during anaphase). resulting in two sets of identical chromosomes. The cell divides, becoming two distinct cells, each with their own nucleus. Usually mitosis occurs wi...
(b) Number of chromatids seen on equator at metaphase I in pollen mother cell of Haplopappus gracilis during meiosis (c ) Number of chromosomes found at one pole after anaphase II during meiosis in butterfly (d) Total number of chromosomes found in all daughter cells formed during meiosis ...
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 ...
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...
1 has been shown to stimulate the activity of ISWI, an ATP-dependent chromatin remodeling factor involved in various DNA processes11. Another level of regulation involves alterations in the subunit composition of these multi-subunit complexes. The mammalian cells contain BAF and PBAF complexes. BAF...
Protein phosphatase 5 (PP5), a serine/threonine phosphatase, has a wide range of biological functions and exhibits elevated expression in tumor cells. We previously reported that pp5-deficient mice have altered ataxia-telangiectasia mutated (ATM)-mediated signaling and function. However, this ...
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...
