  2. Transcription (biology) - Wikipedia

    en.wikipedia.org/wiki/Transcription_(biology)

    Some segments of DNA are transcribed into RNA molecules that can encode proteins, called messenger RNA (mRNA). Other segments of DNA are transcribed into RNA molecules called non-coding RNAs (ncRNAs). Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language. During transcription, a DNA sequence is read ...

    Many viruses replicate this way. The enzymes that copy RNA to new RNA, called RNA-dependent RNA polymerases, are also found in many eukaryotes where they are involved in RNA silencing. [11] RNA editing, in which an RNA sequence is altered by a complex of proteins and a "guide RNA", could also be seen as an RNA-to-RNA transfer.

  4. Gene expression - Wikipedia

    en.wikipedia.org/wiki/Gene_expression

    This RNA is complementary to the template 3′ → 5′ DNA strand, [1] with the exception that thymines (T) are replaced with uracils (U) in the RNA and possible errors. In bacteria, transcription is carried out by a single type of RNA polymerase, which needs to bind a DNA sequence called a Pribnow box with the help of the sigma factor protein ...

    en.wikipedia.org/wiki/RNA

    It has become widely accepted in science [1] that early in the history of life on Earth, prior to the evolution of DNA and possibly of protein-based enzymes as well, an "RNA world" existed in which RNA served as both living organisms' storage method for genetic information—a role fulfilled today by DNA, except in the case of RNA viruses—and ...

  6. Eukaryotic transcription - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_transcription

    Eukaryotic transcription is the elaborate process that eukaryotic cells use to copy genetic information stored in DNA into units of transportable complementary RNA replica. [1] Gene transcription occurs in both eukaryotic and prokaryotic cells. Unlike prokaryotic RNA polymerase that initiates the transcription of all different types of RNA, RNA ...

    Peter Zaffino sat at 2 World Trade Center poring over financial reports on the morning of Sept. 11, 2001, when the first plane struck a neighboring building. Zaffino, known by colleagues for his ...

  8. Introduction to genetics - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_genetics

    The process that copies DNA is called DNA replication. [8] It is through a similar process that a child inherits genes from its parents when a copy from the mother is mixed with a copy from the father. DNA can be copied very easily and accurately because each piece of DNA can direct the assembly of a new copy of its information.

  9. What is a life insurance premium and how does it work? - AOL

    A life insurance premium is the rate you pay for life insurance coverage. Life insurance premiums are determined using factors such as age, health, policy type and coverage limits.
