1 answer:
Pepsi [2]3 years ago
7 0

Answer:

Transcription is the 1st step in the gene expression (DNA based) by which the information in a sequence of DNA is copied into a molecule of mRNA (messenger RNA). Transcription involves 3 steps:

  • Initiation: In which the DNA molecule sequence unwind and form a small open complex.
  • Elongation: In which RNA polymerase moves with the template strand & synthesizing a messenger RNA.
  • Termination: Occurs when an RNA polymerase crosses a termination sequence in the gene. In the termination step, the mRNA strand is complete & it detaches from DNA.  

RNA polymerase is a multi sub-unite enzyme which is responsible for copying the DNA template into an RNA template during the process of transcription.

________ in classical conditioning is the tendency of a new stimulus that is similar to the original conditioned stimulus to eli
SSSSS [86.1K]

Answer:

Generalization

Explanation:

In classical conditioning, generalization refers to the ability of an organism to respond to a stimulus the same way it responds to a stimulus that is similar. For example, generalization is seen in Pavlov’s experiment with dogs, after the pairing of the meat powder with the tone of a bell. The dog which naturally salivates as an unconditioned response to the meat powder (unconditioned stimulus), also later produce similar response (conditioned response) when presented only with the sound of a bell (conditioned response). This is generalization in classical conditioning, as the dog responds in a similar way to meat powder and also to the tone of a bell.
