Answer:
The correct answer is "proteins are extracted from an environment, fragmented, and adaptors are added".
Explanation:
The missing options of this question are:
A) Software aligns sequences and assemble large portions of genome.
B) The samples are subject to polymerase chain reaction for amplification.
C) The sequences of the amplified fragments are determined by next-generation methods.
D) Proteins are extracted from an environment, fragmented, and adaptors are added
The correct answer is option D) Proteins are extracted from an environment, fragmented, and adaptors are added.
Metagenomic sequencing refers to the amplification and determination of all nucleotide sequences in a sample, which might contain multiple microorganisms and viruses in order to understand the presence and proportions of microbiota. Metagenomic sequencing involves the use of next-generation methods, to amplify and characterize all the nucleotides sequences. It is false to affirm that the proteins are extracted directly from the environment in this technique, since metagenomic sequencing is focused on the nucleotide sequences.
Ribosomes<span> are usually found in the rough endoplasmic reticulum, but can also be found throughout the cytoplasm.</span>The job of the ribosome is to make new proteins. If all of a cells ribosomes were weakened, the cell would be unable to make new proteins.
Ok so in this experiment what we want to find is the catalyst for the reaction. Our original reaction is the following. A + B --> C, therefore to find which of the unknown substances (X, Y, and Z) is the catalyst reaction we simply have to do the following:
A + B + X --> C
A + B + Y --> C
A + B + Z --> C
The reaction that produces C much faster than our original reaction A + B --> C will be our catalyst. The reason being that one of the substances will increase the rate of the chemical reaction.
I hope it helps, Regards.
Answer:
A protein that is destined to be secreted from the cell:
- is targeted to the RER as a soluble protein.
Explanation:
The main function of the RER is the synthesis and transport of secretion or membrane proteins.
If you are looking for the RER you could fount it on eukaryotic cells, side by side of the nucleus, and cover in ribosomes.
The answer is cornea…..lens. Most bending of light entering
the eye is bent by the cornea. The lens of the other hand adjusts this bending
further, to focus it squarely on the retina. This is why the focal point of the
lens can be adjusted by changing its shape.
