Gene expression—translation how do cells synthesize polypeptides and convert them to functional proteins?
slavikrds [6]
The language of DNA in form of nitrogen bases read in a set of three termed as codons and it is being translated as language of proteins.

First mRNA is read according to the genetic code which can relate the amino acid sequence to proteins. mRNA can be use as the template to assemble in order the chain of amino acid. Translation starts when the mRNA is decoded and the sequence is elongated  until creating an amino acid sequence. Once the stop codon is reached, translation will be stopped and ribosome will release the polypeptide.

Which type(s) of cell division (mitosis, meiosis l, meiosis Il) reduce(s) the chromosome number by half? Which type(s) of cell d
PSYCHO15rus [73]

Answer:

Which type(s) of cell division reduce(s) the chromosome number by half?

                           Meiosis l

Which type(s) of cell division can be classified as reductional?  

                            Meiosis I

Which type(s) of cell division can be classified as equational?

                           Mitosis and Meiosis II

Explanation:

Meiosis is a type of cell division which occurs in the germ or reproductive cells to produce gametes. It is completed in the two stages, meiosis I and meiosis II.  The cells which are going to divide by meiosis are diploid having two sets of chromosomes. Meiosis I is the first stage of the meiosis. At the end of meiosis I two daughter cells are formed having only 1 set of chromosomes and chromosome numbers are reduced to half. Thus, meiosis I is a reductional division.  

Mitosis and meiosis II is the equational division as after division chromosome number remains the same as in the parent.

malfutka [58]

Answer:

Alright, sure thing.

Explanation:

a. Nucleoid- The nucleoid (meaning nucleus-like) is an irregularly-shaped region within the cell of a prokaryote that contains all or most of the genetic material.

b. Mesosomes- Mesosomes or chondrioids are folded invaginations in the plasma membrane of bacteria that are produced by the chemical fixation techniques used to prepare samples for electron microscopy.

d. Capsid- A capsid is the protein shell of a virus, enclosing its genetic material.

e. Plasmalemma-​ The cell membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment.

What's the difference between an artery and a vein?
emmainna [20.7K]
The difference between an artery and a vein is that arteries are larger, more muscular and more elastic than veins; they carry blood that is under pressure from having been pumped out of the heart; veins are under much less pressure, so they are not as strong
