Answer:
C) A changed to G in the first position of the codon.
Explanation:
In the translation of DNA, triplets or codons of mRNA (a group of three nucleotides) are read according to a genetic code, to build proteins.
Proteins are composed of amino acids. In the translation process, each codon codes for an particular amino acid according to the genetic code as illustrated in the DNA codon table (attached here).
In this table we can see that if the first position of any of the codons coding for Threonine ( ACT, ACC, ACA, ACG) is changed for G, Adenine is going to be encoded instead of threonine.
Answer:
The correct answer is e. the passage of electrons from one energy-generating carrier to another
Explanation:
The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons pass from one member of the transport chain to the next in a series of redox reactions. The energy released in these reactions is captured as a proton gradient, which in turn is used to form ATP in a process called chemosmosis.
These transport molecules, in the inner mitochondrial membrane, are reduced and oxidized, accepting electrons and transferring them to the next molecule, electrons descending from high energy levels to lower ones, that is, from one energy-generating carrier to another. When lowering to other levels, energy is released that will be used in the synthesis of ATP by oxidative phosphorylation.
The Rat’s whiskers are highly sensitive to touch, they brush over the ground, obstacles, food, and other rats. When they bend, it’s follicles send messages to the rat’s brain.
The Rat’s incisors are the four long, sharp front teeth, they use them for gnawing and for grinding food prior to swallowing it.
The answer is yes or the statement is true.
Answer:
C. mRNA serves as the template for DNA, which carries the code to the ribosome for protein construction.
