bacteria), on the other hand, chromosomes form the nucleoid that is located in the cytoplasm given that these organisms do not have a membrane-bound nucleus. Apart from the nucleoid (which is irregularly shaped), plasmids also contain chromosomes and are commonly referred to as extra-...
What are chromosomes made of, from DNA, RNA, and protein, or just DNA and RNA? What are the functions of DNA and through what process does the DNA acquire these functions? What if all the DNA turned into RNA? What is DNA helicase? What does it do?
Chromatin consists of what? (a) protein only (b) DNA only (c) DNA and protein (d) RNA and protein. Explain chromatin remodeling. What is it and what does it do to DNA? Describe the structure of chromatin. What are chromosomes made of, from DNA, RNA, and protein, or just DNA and...
aSince the first proposal of the solenoid model of nucleosome packing, it has been generally assumed that mitotic chromosomes consist of a hierarchy of higher order packaged chromatin fibers. 从nucleosome包装螺线管模型的第一个提案,它一般假设, mitotic染色体包括高次被包装的染色质纤维阶层。[translate] ...
Whereas centrosomes consist of two centrioles surrounded by a matrix of proteins that are involved in microtubule nucleation and anchoring. 12 The function of the centromere is primarily to ensure the correct distribution of chromosomes to daughter cells during mitosis and meiosis, thereby maintaining...
Eukaryotes consist of all multi-cellular organisms, such as plants and animals, along with some types of single-celled life forms. They differ from prokaryotes mainly in that they have a nucleus— a self-contained structure that contains the genetic material in the form of chromosomes made up ...
awhy do you keep silent 正在翻译,请等待...[translate] aa closed chain of chromosomes is formed by copy neutral rearrangements that consist of 3 to more than 40 breakpoint junctions or deletion bridges distributed across multiple chromosomes 染色体一条闭链由包括3超过的拷贝中立重新整理形成横跨多染色...
one flagellum or tail, which allows them to move independently. The head contains very little cytoplasm compared to other cells and carries very densely packedchromosomeswithin thenucleus. Like all sex cells,spermcells are haploid, containing only half the number of chromosomes typical of the ...
This paper primar- ily addresses qualitative responses to questions concerning the process of understanding test results, and the meaning of the results, for example, "What is your understanding of what the test results mean in regard to your child's chromosomes?" "How well do you feel like ...
What material makes up chromosomes? Testes are the male gonads and house sperm, ovaries are the female gonads and house eggs. A. True B. False Which kind of cell division produces an adult from a zygote? During which process are gametes (sperm and egg) produced? (a) Mitosis (b) Buddin...
