Answer: Your answer would be A
Explanation:one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Answer:
The chart shows how well each beetle with each trait were able to survive in their environments, and Mutant 1 was clearly out living the other two, because as you can see mutant 2 has only last for at least one generation, while the non-mutated one lived a little longer. This is because Mutant 1 developed the trait that made its shell darker, and thus it's easier for them to hide from predators, and they were able to successfully pass on their genes to their offspring so now they can do the same.
<span>. Messenger RNA (mRNA) is
synthesized from a gene segment of DNA which ultimately contains the
information on the primary sequence of amino acids in a protein to be
synthesized. The genetic code as translated is for m-RNA not DNA.
The messenger RNA carries the code into the cytoplasm where protein
synthesis occurs. The cell does
not contain large quantities of mRNA. This is because mRNA, unlike other RNAs
is constantly undergoing breakdown.
2. In
the cytoplasm, ribsomal RNA (rRNA) and protein combine to form a
nucleoprotein called a ribosome. The ribosome serves as the site and
carries the enzymes necessary for protein synthesis. The ribosome attaches
itself to m-RNA and provides the stabilizing structure to hold all substances
in position as the protein is synthesized. Several ribosomes may be attached to
a single RNA at any time. </span>

3. Transfer
RNA (tRNA) contains about 75 nucleotides, three of which are called
anticodons, and one amino acid. The tRNA reads the code and carries the
amino acid to be incorporated into the developing protein. Part of the
tRNA doubles back upon itself to form several double helical sections. The
tRNA "reads" the mRNA codon by using its own anticodon. The actual
"reading" is done by matching the base pairs through hydrogen bonding
following the base pairing principle. Each codon is "read" by various
tRNA's until the appropriate match of the anticodon with the codon occurs.</span>
genes control traits so when a gene is changed the trait changes
A
