What are the 3 laws of inheritance?
nikdorinn [45]

The three laws of inheritance are :

Law of Dominance. Law of Segregation. Law of Independent Assortment.

what is law of dominance?

First, according to the Law of Dominance and Uniformity, some alleles—variants of a specific gene located at the same chromosomal locus or location—are dominant over other alleles for that gene.

As it relates to genetics, the term "inherited" describes a feature or variation that is encoded in DNA and passed from parent to child during reproduction. The laws of Mendelian genetics govern inheritance. A will needs to be admitted to probate in order for the inheritance procedure to start. The probate court examines the will, approves an executor, and formally distributes assets to recipients in accordance with the terms. The executor will pay off any outstanding obligations of the deceased prior to the transfer

The transcription terminator stops DNA polymerase, AND results in the polymerase falling off the DNA template. adds a terminator
Ivan

Answer:

Results in a hairpin loop structure in RNA, AND results in the polymerase falling off the DNA template.

Explanation:

As the RNA polymerase arrives at the terminator site, it pauses. The termination of RNA transcription occurs when an RNA transcript with a self-complementary sequence is formed leading to the formation of the hairpin structure. The hairpin structure has 15-20 nucleotides.  

The hairpin structure of RNA weakens A=U base pairs in RNA-DNA hybrid and/or weakens the interaction between RNA and RNA polymerase. The overall effect is the dissociation of RNA polymerase from the complex and termination of the transcription.
