Answer: a
Explanation: transcription takes place in the nucleus. RNA leaves the nucleus to go to the ribosome where translation occurs.
Answer:
The correct answer will be option- B.
Explanation:
The Transduction is the process of the genetic transfer by which the foreign DNA is incorporated in the genome of the cell using virus or bacteriophage. The process of transduction was discovered by the Zinder and Lederberg in 1952 in the species of<em> Salmonella</em> bacteria. The transduction process is of two types: generalized and specialized transduction.
Thus, option- B is the correct answer.
I believe it would be an observation
Observation in scientific process refers to gathering facts and information. In this particular context, we could see that the microbiologist is simply stating what he/she saw on the mold on the agar plate. The microbiologist simply writing down all the facts without making any explanation or assumption.
Koalas benefit from tress because then can climb on them to keep away from danger such as other ground predators, Trees can also serve as a food source for them to eat in day to day life.
Answer:
- Based on this information you come to the conclusion that you have been able to identify in these cells the structure of <em>microfilaments</em> or <em>actin filaments</em>.
- <em>Oviductus oblatus</em> are indeed eukaryotic cells
Explanation:
In eukaryotic cells, the cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a <u>polymer of proteinic subunits</u> united by weak, not covalent connections.
The microfilaments are the thinnest of the three structures. They have a <u>diameter of 7 nanometers</u> and are <u>composed of many proteinic monomers</u> united. This monomeric protein is called actin. Many monomers get combined to form a structure that assembles a double helix.
Due to the fact that these microfilaments are made of actin monomers, they are also known as actin filaments.
Actin filaments have directionality which means that their extremes have different structures.
In eukaryotic cells, genes that codify for actin microfilaments are highly conserved in all organisms, which is why <u>they are often used as molecular markers</u> for different studies.
