Is all of an organism's DNA contained in one cell of an organism? Does eukaryotic DNA supercoil? Which structure is found only in eukaryotes? How is DNA packaged in the nucleus of somatic cells? Chromatin contains proteins called How does the nucleus control which...
Do eukaryotes do mitosis? In particular, eukaryotic cells divide using the processes of mitosis and meiosis.Mitosis is common to all eukaryotes; during this process, a parent cell splits into two genetically identical daughter cells, each of which contains the same number of chromosomes as the pa...
How do the proteins of the transcription machinery access DNA that is tightly associated in chromatin? In eukaryotes, describe what genes each RNA polymerase transcribes. How are DNA, RNA, and proteins related in the cell? How are enzymes involved in the process of genetic transcription? a)...
Classical nuclear import in higher eukaryotes and yeast is sensitive to various forms of stress [29], [30], [31], [32]. Ultimately, severe stress conditions inhibit nuclear transport and may also lead to cell death [31]. The molecular mechanisms that link oxidative stress to changes in nucl...
DNA evidence suggests that the first eukaryotes evolved from prokaryotes, between 2500 and 1000 million years ago. ... Like the plants, animals evolved in the sea. What was the first tree? The earliest trees were tree ferns, horsetails and lycophytes, which grew in forests in the ...
2. Multiple Rieske proteins in eukaryotes In several of the completely sequenced genomes from eukaryotes multiple Rieske genes can be found. Organisms that are most likely to contain more than one Rieske iron–sulfur protein are higher plants and green algae. In higher plants, the Rieske protein ...
Explain how the genetic code allows translation of the information contained in an mRNA into a protein sequence. Transcription is the transfer of genetic information from ___. a. DNA to RNA. b. tRNA to mRNA. c. DNA to mRNA. d. mRNA to tRNA. What ...
A) DNA replication B) Transcription C) Translation What is the process of transcription and translation within biology? What are some examples? Why does a cell need to carry out transcription before translation? Where does RNA synthesis in eukaryotes occur? What are translation and transcription in...
The introduction of new diversity from exotic cultivars or wild relatives relies on meiotic recombination (also known as crossover; CO), a biological process common to all eukaryotes with sexual reproduction including angiosperms (for review see [11]). CO is a large reciprocal exchange of DNA seg...
