DNA is replicated in the nucleus of eukaryotes, but in the cytoplasm of prokaryotes. Why is this?
umka2103 [35]

Answer:

In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All three processes can occur simultaneously.

   In eukaryotes (organisms with a nuclear membrane), DNA undergoes replication and transcription in the nucleus, and proteins are made in the cytoplasm. RNA must therefore travel across the nuclear membrane before it undergoes translation. This means that  transcription and translation are physically separated. The primary transcript, heterogeneous nuclear RNA (hnRNA), undergoes extensive post-transcriptional processing to make a messenger RNA (mRNA)molecule that can pass through the nuclear membrane.

Orms of obvious, overt prejudice, which are considered inappropriate by most social standards today, are sometimes called:______
zhannawk [14.2K]

Answer:

Discrimination        

Explanation:

Discrimination of prejudice refers to the act of treating a person or people in a way that is wrong, unlawful, and inconsistent with the generally accepted moral standards just because they are different especially with respect to age, nationality, gender, etc

There are two categories of discrimination:

  1. Overt and
  2. Covert.

Discrimination or prejudice is over when those who practice it are unafraid to make their thoughts and actions public. Many times this is so because the society in which they live condones such behavior and because there are no repercussions, they bold to make their unjust acts public. For example, name-calling, intentional rejection of job applications, etc.

Covert refers to using the system or giving logical reasons for discriminatory behavior. This is more subtle. For example, an employer may say they are not taking females due to the prerequisites of the job. Refusing "nicely" to be treated by a person of color in a hospital is another example.

Covert aggression of prejudice is often masked and occurs where the laws are relatively stiff on those who practice them. Also, a society that is evolving from largely prejudicial to less discriminatory will see more covert forms that overt forms of discrimination because those who practice overt prejudice are bold because they know that there are many more who think like them.

Cheers!
