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.
Answer:
The correct answer will be- homologous structures
Explanation:
The history of how life has survived on the earth can be studied through a field of biology called evolutionary biology.
Studying the anatomical features of the organisms and the collected specimens (fossils) shows that some organisms posses similar anatomical structures which could be performing different functions.
The structures in organisms which are similar in their structure are thought to have derived from a common ancestor and are known as "homologous structures.
"
Thus, homologous structures are the correct answer.
The answer is genus plasmodium. There are diferent species
under the genus including falciparum, vivax, malariae, and knowlesi. The most
common is P. malariae and is the cause of Malaria that is the cause of most
deaths among young children and pregnant mothers in developing countries.
A. And B.
Maltose or as known as malt sugar is a disaccharide combined by a dehydration reaction with two glucose molecules.
The most known disaccharide is sucrose or commonly known as table sugar which is made of the monomers glucose and fructose.
