Skeletal muscle fibers contain striations. what is the best description of a striation?

Biology

Answer: alternating dark and light bandsof protein filaments
Skeletal muscle fibers contain striations that can be described as alternating dark and light bands of protein filaments. Actin, tropomyosin, and troponin are among the protein filaments. The dark bands are the so-called A bands. Alternating light bands are referred to as I bands.

mojhsa [17]
<h2>Evolution of phylogenies </h2>

Explanation:

  • The genome of the endosymbiont is all the more firmly identified with individuals from the gathering in which it initially developed, while the nuclear genome of the inundating living being has its own evolutionary trajectory.  
  • The accumulation of various inheritable attributes after some time which prompted the arrangement of another species  
  • Nuclear and organellar genes advanced at various rates, clouding developmental connections.  
  • Some mitochondrial genomes have been decreased definitely in size, losing a large number of the protein genes encoded in creature mtDNA just as a few or all mtDNA-encoded tRNA genes.
  • At ∼6 kb in size, the mitochondrial genome of Plasmodium falciparum (human intestinal sickness parasite) and related apicomplexans is the littlest known, harboring just three protein genes, profoundly divided and improved little subunit (SSU) and enormous subunit (LSU) rRNA genes, and no tRNA genes.
  • In stamped differentiate, inside land plants, mtDNA has extended generously in size (>200 kb) if not in coding limit, with the biggest known mitochondrial genome right now.

The access is most heavily limited by Climate

In an extremely dry and hot climates such as desert, it will be incredibly hard to access potable water because they evaporate really quickly

Meanwhile in a wet and cool climates such as rain forest, it will be extremely easy to access potable water

In order to initiate transcription in eukaryotes, _______. View Available Hint(s) In order to initiate transcription in eukaryot
laila [671]

Answer:

transcription factors bind to the promoter, and RNA polymerase is then recruited to begin transcribing the gene

Explanation:

The transcription process in eukaryotes happens in 3 stages:

  1. Initiation
  2. Elongation
  3. Termination

The initiation of transcription starts when a set of proteins called the transcription binds to the promoter region of a gene on the coding strand of DNA. Thereafter, the RNA polymerase enzyme binds to the promoter region thereby opening up the double helix structure of the DNA in anticipation of transcription.

During elongation, RNA nucleotides are added to the growing RNA strand in 5' to 3' direction with the DNA unwinding and winding back as the polymerase moves along the coding strand in 3' to 5' direction.

Transcription terminates when the RNA polymerase gets to the end of the gene being transcribed signalled by a sequence of DNA known as the terminator.

<em>Hence, in the illustration, the correct answer would be that the transcription factors bind to the promoter, and RNA polymerase is then recruited to begin transcribing the gene.</em>
