Mature red blood cell doesn't contain a nucleus. - Moreover, they lack organelles like the endoplasmic reticulum or mitochondria. ... Unlike classical mammalian erythrocytes, all non-mammalian chordates such as Amphibians have RBC carrying a nucleus in the middle of the cell. Hence, the correct...
Does prokaryotes or archaea have a mitochondria? Why is protein synthesis a two-part process? Why is it more complicated for a retrovirus to replicate? Why do cells need both tRNA and mRNA? What is the purpose of DNA replication in DNA structure?
Perhaps some mitochondrial proteins (mitoproteins) are more amenable to being retargeted to mitochondria after nuclear transfer. To determine how many nucleus-encoded mitoproteins have detectable N-terminal mitochondrial targeting signals (MTSs), we used a number of programs to predict MTSs in genes en...
There are 13 main parts of an animal cell:cell membrane, nucleus, nucleolus, nuclear membrane, cytoplasm, endoplasmic reticulum, Golgi apparatus, ribosomes, mitochondria, centrioles, cytoskeleton, vacuoles, and vesicles. What is called cell? Cells arethe basic building blocks of all living things....
RNA can act as: a. protein b. both genes and enzymes c. sugar d. mitochondria In eukaryotic cells, genetic information is found in the form of DNA. Is this true for prokaryotic cells? How are prokaryotes and eukaryotes different in terms of the RNA polymerases involved in transcription?
"It doesn't even have lymphocytes. " Such skeptics may be unaware that the mouse is fast becoming as tractable a model organism as the fly, and that humans may... B Beutler - 《Current Topics in Microbiology & Immunology》 被引量: 2发表: 2008年...
[123]. This is perhaps unsurprising given the role of oestrogen in upregulating the production of ROS by mitochondria [126,127]. It seems reasonably clear that elevated levels of oxidative stress during relapse could account for data indicating upregulated transcription of HERV-W/HERV-H in ...
The heart’s capacity to function continuously is related to the presence of mitochondria in the myocytes. Mitochondria contain enzymes that participate in oxidation and reduction processes providing energy to the cell. Intercalated disks are found between adjacent myocytes and combine the myocytes into ...
How can prokaryotes perform cellular respiration if they do not have mitochondria? How does water form during cellular respiration? How do unicellular organisms maintain homeostasis? How do cells capture the energy released by cellular respiration?
What type of cells have cilia? What are circulation cells? What do goblet cells secrete? What do mitochondria do for epithelial cells? What do helper B cells do? What is cell specialization? What type of cells undergo mitosis? What type of cells do not undergo mitosis?
