A) In how many cases in the genetic code would you fail to know the amino acid specified by a codon if you knew only the first t
Vesna [10]

Answer:

a) 28 cases

b)  3 cases

Explanation:

a) From the table of genetic codes, there are 28 codons that specify more than one amino acid assuming only the first two nucleotides are considered. In these cases, one cannot outrightly specify the amino acid the genetic codes are coding for without knowing the last nucleotide of the codes. <em>For example, UU can be for Phenylalanine or Leucine, CA can be for Histidine or Glutamine, etc. </em>

b) From the table of genetic codes, the first two nucleotides of Arginine can be either of CG or AG, that of Serine can be either of UC or AG while that Leucine can be either of CU or UU. Only in these <u>3 cases</u> would one fail to know which are the first two nucleotides assuming the name of the amino acids are given.

The sympathetic chain contains a group of cell bodies called the sympathetic chain Blank 1. Fill in the blank, read surrounding
lions [1.4K]

Answer:

The sympathetic chain contains a group of cell bodies called the sympathetic chain GANGLIA. This structure contains a second cell body for the sympathetic nervous system, the first in the series being found in the THORACOLUMBAR REGIONS' lateral horn of spinal segments T1-L2. The purpose of the VENTRAL AND DORSAL rami is to carry visceral motor and visceral sensory neurons to and from this sympathetic chain.

Explanation:

The sympathetic trunks (sympathetic chain, gangliated cord) are a paired bundle of nerve fibers that run from the base of the skull to the coccyx.
