14: Operons allow prokaryotes to replicate DNA at the appropriate time.
Operons are specific regions of genes that are linked to a singular process. They ensure that the expression of these genes does not go unchecked and only occurs when necessary. Two key examples of this in humans are the lac operon and trp operon.
15. The central dogma of molecular biology is:
DNA to RNA to Proteins
Protein Synthesis occurs in 3 steps.
First our DNA is translated into RNA. Next the RNA is sequenced into Amino Acids by reading the corresponding 3-Base Codons. These Amino Acid sequences form various protein structures.
RrTt ....means brown leaves and tall stems !
so answer is D !
Answer:
When a liquid is heated, the molecules gain energy. This means they move and vibrate more, causing them to escape in the atmosphere.
Answer:
Mutation, migration, genetic drift, and natural selection are all processes that can directly affect gene frequencies in a population.
