Luba_88 [7]3 years ago
7 0
There are three types of muscles namely; (1) cardiac muscles, (2) smooth muscles, and (3) skeletal muscles. Sarcomeres are the functional contractile unit of both cardiac and skeletal muscles; both of which are striated muscles. Smooth muscles, on the other hand, have no sarcomeres instead the contractile structures (actin and myosin) are dispersed within the cell body.

Question:All known organisms use genetic information to produce protein molecules via the same genetic code. This finding strongly supports the hypothesis that __________.

a) the earliest macromolecules probably arose when lightning struck an oxygen-free atmosphere

b) all organisms are descended from one or a few common ancestors

c) the genetic code readily evolves by natural selection

d) there's only one possible way to encode information in a macromolecule

Answer:

b) all organisms are descended from one or a few common ancestors

Explanation:

Protein synthesis occurs when the nucleotide sequence of the mRNA is read in the form of genetic codes. A specific genetic code specifies the same amino acid in all living beings. For example, the code "UUU" codes for phenylalanine in all the living beings irrespective of their species. This suggests that all the life forms have originated from one or few common ancestors and the genetic code has been preserved during the course of evolution of various species.
