What does Polyteny mean?

The condition of a chromosome, nucleus, or cell in which the DNA has repeatedly replicated, without subsequently separating (see endomitosis). This results in a cablelike giant chromosome, consisting of up to 1000 parallel chromatids and often showing conspicuous transverse banding.

What happens during endomitosis?

endomitosis The doubling of the chromosomes within a nucleus that does not divide. The doubling may be repeated a number of times in a single nucleus. It occurs mainly in insects, where different adult tissues have specific polyploid numbers; it also occurs in some vertebrate tissues.

What does Endocycle mean?

The endocycle is a common cell cycle variant in which cells successively duplicate genomic DNA without segregating their chromosomes during mitosis.

How does endoreduplication occur?

Endoreduplication occurs when a cell undergoes extra rounds of DNA synthesis (S-phase) without any mitosis or cytokinesis to produce an endopolyploid cell. This produces multiple chromatids of each chromosome.

What is the difference between polyploidy and Polyteny?

is that polyteny is (molecular biology) the presence within a cell of polytene chromosomes (large chromosomes with multiple synapsed chromatids) while polyploidy is (label) the state or condition of being a polyploid; having more than the usual two homologous sets of chromosomes.

What is meant by Endopolyploidy?

: a polyploid state in which the chromosomes have divided repeatedly without subsequent division of the nucleus or cell.

What is human Endomitosis?

Endomitosis is one of the processes leading to endopolyploidy, in which the stages of mitosis (prophase, metaphase, anaphase) take place inside the nuclear membrane and without spindle formation.

What is the difference between Endomitosis and endoreduplication?

Endomitosis is similar to endoreduplication in that the DNA content is doubled; however, it differs from endoreduplication in the resulting number of chromosomes. The chromosome number per cell after endomitosis is doubled.

What is the difference between endomitosis and endoreduplication?

What is meant by endopolyploidy?

What is the process of communication?

Communication Process. Definition: The Communication is a two-way process wherein the message in the form of ideas, thoughts, feelings, opinions is transmitted between two or more persons with the intent of creating a shared understanding.

Who are the participants in the communication process?

In communication models, the participants are the senders and/or receivers of messages in a communication encounter. The message is the verbal or nonverbal content being conveyed from sender to receiver. For example, when you say “Hello!” to your friend, you are sending a message of greeting that will be received by your friend.

How is the process of communication a cyclic one?

The process of communication is a cyclic one as it begins with the sender and ends with the sender in the form of feedback. It takes place upward, downward and laterally throughout the organization. The process of communication as such must be a continuous and dynamic interaction, both affecting and being affected by many variables.

How is the process of Communication really linear?

When you think about communication in its simplest form, the process is really quite linear. There’s a sender of a message—let’s say you—talking. You, the sender, have a thought. You put that thought into words, which is encoding the message. And then there’s a recipient of a message—in this case your coworker Nikola.
