In which step of protein synthesis does the rRNA make protein?
Inessa [10]

Answer:

Translation is the second part of the central dogma of molecular biology: RNA → Protein. It is the process in which the genetic code in mRNA is read to make a protein. Translation is illustrated in the diagram below. After mRNA leaves the nucleus, it moves to a ribosome, which consists of rRNA and proteins.

Explanation:

Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.

The highlighted structure separates the oocyte from the externally located ________. zona pellucida primary follicle corona radi
Naya [18.7K]

Answer:

Granulosa cells                          

Explanation:

Foliculogenesis is a dynamic and complex process through which the follicle goes through many stages of development in a short period (approximately 60 days in humans and some chimpanzees).

The stages classification is based on morphological changes such as follicular size or diameter, the number of follicular cell layers, etcetera. These classifications might vary among authors but could be denominated as:

  • Primordial follicle
  • Primary follicle
  • Secondary follicle and
  • De Graaf follicles (This is the one shown in the image)

Through each stage, there are certain modifications in the oocyte, follicular cells, and connective tissue. As the oocyte grows, the follicular cells might reach a size twice or three times bigger than the ones of the primordial follicles. Their shape also changes and they adopt an aspect of stratified epithelium. Their cytoplasm gets a granulous aspect, after what these cells receive the name of <u><em>granulous cells</em></u>. The De Graaf follicle characterizes for having a space named follicular antro that displaces the oocyte to one of the sides.    

The oocyte at this point gets surrounded by <u>zona pellucida</u> and <u>corona radiata </u>.    

The follicular antro (The highlighted structure) separates the oocyte from the externally located <u>granulosa cells</u> or follicular cells.

The seeds are plant tissue and plants are able to perform both cellular respiration and
katrin [286]

Respiration is process where plant produce heat  

Explanation:

Respiration is essential component for every living thing this. Respiration help living thing get energy and stay alive. In plant cellular respiration is used to convert nutrient which is present in soil and this process can be understand as a cellular activity. In plants seeds play vital role.

The basic difference between respiration and photosynthesis is in respiration plant consume nutrient for survival and alive plant cell but in photosynthesis plant is able to make their own food.  In respiration only plant produce heat energy

<u>The formula of Respiration: </u>

Oxygen + glucose – Carbon dioxide + water + heat energy  

<u>The formula of Photosynthesis </u>

Carbon dioxide + Water + Sunlight – Oxygen + glucose
