Traits that enable an organism to reproduce, without necessarily helping them to survive, are often selected for. Darwin called
4vir4ik [10]
The example that does not exhibit sexual selection is:
D. male elephant seals fighting over territory and potential female mates
The competition for territory is also one that helps the elephant seals survive. This is because a seal with a larger territory is likely to have access to a greater amount of resources, ensuring its survival.

If a nucleotide lacking a hydroxyl group at the 3' end were added to a pcr reaction, what would be the outcome?
Verdich [7]
The correct answer is b. no additional nucleotides would be added to a growing strand containing that nucleotide.
<span>
Nucleotides without a 3’hydroxy group are called dideoxynucleotides (ddNTD). Dideoxynucleotides are inhibitors of DNA polymerase because after being added in PCR reaction no further nucleotides can be added as no phosphodiester bond can be created (usually 3' hydroxyl group of the previous nucleotide attaches to 5' phosphate of the current nucleotide).</span>

Which of the following is directly involved in driving protein import into the mitochondrial matrix space? A. GTP hydrolysis out
kumpel [21]

Answer:

The correct answer is D; ATP hydrolysis inside mitochondria

Explanation:

Proteins imports brought into the matrix of mitochondria are normally taken up from the cytosol in practically less time after their discharge from ribosomes. Transportation of protein imports into the matrix is driven by energy which is supplied by:

  • <u>ATP hydrolysis outside the mitochondra: </u>this occurs in the first step of translocation process. ATP hydrolysis drives the release of newly synthesized polypeptides from the hsp70 group of chaperone proteins.
  • <u>an electrochemical proton gradient</u> across the inner mitochondrial membrane maintained by electron transport process in the inner membrane.
  • <u>ATP hydrolysis in the matrix</u>: Hsp70 chaperone proteins in the matrix space likewise have a job in the translocation procedure, and they are the third point in the import procedure at which ATP is expended.
