The diagram below shows a portion of DNA. The nucleobases adenine, thymine, cytosine, and guanine are matched together in
base pairs, and the order of these base pairs makes a genetic code.
Adenina
O
-Thymine
Cytosine
Guanine
Which describes the genetic code in a human?
Different genetic codes appear in each different type of cell.
Every human has the same exact genetic code.
Genetic codes change frequently in reaction to external factors.
A genetic code determines the physical traits of the body.

What statements describe a host organism?

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
