Answer:
d. Genes that play a role in the same metabolic pathway are organized into an operon.
Explanation:
In prokaryotic organisms like bacteria, polycistronic mRNAs exist which means that each gene does not have a separate promoter of its own. In fact many genes are under the control of a single promoter. These genes being a part of same metabolic pathway are organized into an operon. For example, lac operon and tryptophan operon. In lac operon, three genes named as β-galactosidase, permease and transacetylase are expressed under a single promoter which is known as lac promoter.
In contrast to this, in eukaryotes the mRNAs are monocistronic i.e. only a single gene is controlled under a single promoter.
Answer:
On the tan sand more light colored mice will survive because they blend in and on the dark lava rock more dark colored mice will survive and the allele for dark fur will be passed on to their offspring.

Answer:
a codon can be found on mRNA
Explanation: codons are created when groups of nucleotides are conected to form a animo acid. the formation is all in the mRNA then the animo acids combine to form proteins. proteins are formed when animo acids are "dehydrated" and form a water molecule then the rest combine into a protein and that protein can be in any form for various tasks.
The correct answer is - One parent has white feathers and one has red/white feathers.
The offspring, the chickens, have feathers that are only white, or feathers that are with both red and white color. There's not a single individual in the offspring that has only red feathers.
That leads to the conclusion that one of the parents had white feathers, while the other had red and white feathers, as those are the only two combinations in their offspring.
A parent that has only red feathers can be excluded (though not 100%) because there's not a single chick out of the 30 chicks with red feathers, and if there was a red feathered parent the chances are very high that at least one of them will be red feathered as well.
