How is the protein created from the mRNA sequence which reads AUGAUAGUGUAC different from the protein created from one that read
adoni [48]
To transcribe the mRNA to make the DNA, we use genetic codes called codons. These are composed of three amino acids clumped together. It could be Adenine(A), Guanine(G), Uracil(U) and Cytosine (C). The difference is that first thread contains GUG, while the second one contains AGU. GUG is for Histidine while AGU is for Serine.

frosja888 [35]

Answer:

Option (A)

Explanation:

The Precambrian represents the time period, right from the beginning of the earth to about 540 million years back. It is divided into 3 parts, namely the Hadean, the Archean and the Proterozoic. Throughout this geological time, vast changes have taken place on earth. The first life forms of about 3.8 billion years old, that existed on earth were the simple unicellular organisms, whose traces were only found at some particular places. These organisms were very small and are comprised of soft bodies, so they were affected by the earth's dynamic processes. The organisms in order to get fossilized must contain hard parts. Due to the presence of soft bodies, the organisms were not fossilized and so it took a long time to demarcate that the late Precambrian organisms were animal-like life.

hence, the correct answer is option (A).

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by a(n) _________ system. Multiple Choice riboswitch
zmey [24]

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.

  • Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
  • A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
  • Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.
