Answer: Promoter

Explanation:

Transcription is the first step in gene expression which consists of copying the DNA sequence of a gene to produce a RNA molecule. There are enzymes called <u>RNA polymerases which perform this process of transcription</u>. These enzymes bind nucleotides (the monomers which are part of the nucleic acids) to create a RNA strand using a DNA strand as a mold.

A promoter is a region of DNA that controls the initiation of transcription of a given portion of DNA to RNA. Therefore they promote the transcription of a gene. <u>The promoter region is composed of a specific sequence of DNA located just where the starting point of the DNA transcription is</u> and contains the information needed to activate or deactivate the gene it regulates. <u>The promoter has a binding site for the RNA polymerase enzyme </u>in charge of mRNA synthesis and when it recognizes this site, transcription begins.

frosja888 [35]

Answer:

An unconditioned response.

Explanation:

Pavlov was the process of studying salivation in dogs as a part of a research program on chewing and digestion. This is known as a normal reflex that is under personal choice or control and also called an unlearned evolutionary response.

In terms of Pavlov's analysis of learning, Pavlov built a device that would help to accurately measure the amount of saliva produced by dogs. In the case of Pavlov dogs, the food is called as the stimulus and salivation is called as a response.

The mechanism that breaks the linkage between linked genes is
gregori [183]

Answer:

Crossing over

Explanation:

Crossing over is the process during which two chromatids of two homologous chromosomes exchange part of their genetic segments. It occurs during the pachytene stage of prophase I of meiosis I.

Linked genes are mostly inherited together and do not exhibit independent assortment. However, when linked genes are present far apart from each other on the same chromosome, crossing over can occur between them to produce recombinant chromatids. Therefore, crossing over can break the linkage and produce recombinant progeny as it occurs during the independent assortment of unlinked genes.

This shows that the animals are similar and that they develop similarly, implying that they are related, have common ancestors and that they started out the same, gradually evolving different traits, but that the basic plan for a creature's beginning remains the same.</span>
