The statement about eukaryotic cells is NOT true - Eukaryotic cells are usually smaller than prokaryotic cells

Cells are fundamental units and are mainly two types eukaryotic cells and prokaryotic. There are various structural and functional differences and similarities found in them.  

Prokaryotes and eukaryotic cells have the following difference:  

Prokaryotic cells lack a true nucleusProkaryotic cells lack other membrane-bound organelles.Eukaryotic cells have more organelles, enzymes, and molecules, therefore, prokaryotic cells are simpler.Prokaryotic cells are comparatively smaller than eukaryotic cells.Prokaryotic cells are evolved before eukaryotic cells.

Thus, the statement about eukaryotic cells is NOT true - Eukaryotic cells are usually smaller than prokaryotic cells

Explain how specific proteins are formed from a strand of mRNA.

Answers

Answer:

During translation, ribosomes move along an mRNA strand, and with the help of proteins called initiation factors, elongation factors, and release factors, they assemble the sequence of amino acids indicated by the mRNA, thereby forming a protein.

Explanation:

Answer:

Explanation:

Los ARN mensajeros, también conocidos como ARNm, son uno de los tipos de ARN que se encuentran en la célula. Éste en particular, como la mayoría de los ARN, se sintetiza en el núcleo y luego se exporta al citoplasma, donde la maquinaria de traducción, la maquinaria que realmente fabrica las proteínas, se une a las moléculas de ARNm y lee en ellas el código para producir una proteína específica. Así que en general, un gen, el ADN de un gen, puede ser transcrito en una molécula de ARNm que puede acabar dando lugar a una proteína específica.

As an outer layer that we can see and touch, the epidermis protects us from toxins, bacteria, and fluid loss. It consists of 5 sublayers of keratinocyte cells. These cells, produced in the deepest inner, basal layer, migrate to the surface of the skin. As they do so, they mature and go through a series of changes.

What are the building blocks of proteins? If all proteins are made of the same
building blocks, how can there be so many different types of proteins with different
functions?

Answers

Answer:

The basic building blocks of proteins are called amino acids. In proteins, amino acids are arranged into a linear molecule called a polypeptide chain. Some proteins only consist of a single polypeptide chain while more complex proteins are made out of multiple polypeptide chains bonded together.

Explanation:Proteins are formed out of long linear molecules of amino acids called polypeptide chains. The identity and function of a protein are determined by its sequence of amino acids and the 3-D structure of its polypeptide chains. Amino acids are stored in DNA in the form of sequences of nucleotide bases.
