Explanation:
A new calculation reveals just how intensive that process is. According to biologists Ron Sender and Ron Milo of the Weizmann Institute of Science in Israel, your body replaces around 330 billion cells per day. At that rate, your body is making over 3.8 million new cells every second.
Answer: The answer is mutation and natural selection
Explanation:
When members of a population interbreed (marry one another), genes are recombined and spread in the entire population resulting in gene flow. However, the Dunkers family decision not to intermarry would prevent gene flow, rather favor the NATURAL SELECTION of some genes, making the DUNKERS family genetically unique from the remaining population
Precipitation rate exceeds the infiltration rate
Answer:
Explanation:
Incomplete dominance occur when two allele expresses itself in the phenotype of an organism.
Its a situation where by an allele is not dominant over another other in an heterozygous condition but it gives a blend of the two allele in the phenotype of the offspring.
Example is the phenotype of a 4'o clock plant that gives pink flower when a red flower is crossed with white flower.
Answer:
A single antibody gene can code for different related proteins, depending on the splicing that takes place post-transcriptionally.
Explanation:
According to the "one-gene, one-enzyme hypothesis", a gene code for single specific enzyme only. Beadle and Tatum proposed the one-gene, one-enzyme hypothesis that states that a gene encodes the genetic information for the synthesis of one enzyme only. However, alternative splicing in eukaryotes allows the formation of more than one related proteins/enzymes from a single gene.
For instance, alternative splicing of single primary transcript transcribed from an antibody gene allows the formation of multiple proteins. The primary transcript encoded by this gene has a segment of the gene that serves as either intron or exon. Depending on particular combinations of exons retained after splicing, multiple related proteins are formed by respective mRNA.
