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.
Answer: Thanks for the tips.
Explanation:
The green sample possibly contains algae or some other sort of bacteria
Answer:
The second one is correct
Explanation:
A leukocyte is responsible for the immune system
Are wrong because they belong to second part of meiosis(meiosis2). And it is not metaphase1 because metaphase is when the chromatides are lined up in the middle of a cell.
