Answer:
Chemical properties are very useful in identifying substances. However, unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance.
Answer:
The correct answer is option d. "A region of DNA sequence upstream of a gene where transcription factors bind".
Explanation:
Cis-regulatory elements (CREs) are fragments of DNA that do not encode to a protein, but regulate the transcription of nearby genes. CREs regulation is based on binding to transcription factors. These elements are vital for the regulation of complex molecular mechanisms that involve the participation of multiple genes. Additionally, CREs could participate in pleiotropy (a single gene being responsible for the development of multiple traits), because a single transcription factor could bind to different CREs.
Answer:
<u><em>The correct option is D) His results gave the first evidence that atoms were made up of smaller particles.</em></u>
Explanation:
Before the experiments performed by Thomson,scientists believed that atoms were the smallest particles with no sub units. The experiments performed by Thomson provided evidence that atom is made up of even smaller particles. The cathode ray experiment performed by Thomson led to the discovery of electrons which are the negatively charged particles of an atom. The protons are the positively charged particles of an atom. Whereas, the neutrons have no charge.
Answer:
The process of making mRNA from DNA is called transcription, and it occurs in the nucleus. The mRNA directs the synthesis of proteins, which occurs in the cytoplasm. mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes.
Explanation:
I think the answer is liquefaction but correct me if i am wrong.
