Answer:
D.DNA-mRNA-Amino Acid-Protein-Trait
Explanation:
The relationship between DNA and the trait of an organism involves a process called GENE EXPRESSION. DNA is a molecule that contains information needed for the survival of an organism. However, this information must be expressed in order to be used.
The process of gene expression involves two major processes namely: transcription and translation. Transcription involves the synthesis of mRNA from DNA template while translation involves the synthesis of amino acid sequence from mRNA. The amino acid sequence encodes PROTEIN, which determines the TRAIT of an organism.
Based on this explanation, the correct sequence that best represents the relationship between DNA and the traits of an organism is: DNA-mRNA-Amino Acid-Protein-Trait
The littoral zone is also known as the intertidal zone is the place where the land and sea meet and is found between the low and high tide zones. This diverse marine ecosystem is witnessed along the coastlines globally. It comprises ample nutrients and oxygen and is considered home to numerous species.
The littoral zone is further differentiated into vertical zones, like the spray zone and low tide zone. Spray zone also known as the upper littoral, and is dry in the majority of the time, but sprayed with water at the time of high tides. It gets flooded at the time of extreme high tides and storms.
The low tide zone also is known as the lower littoral zone, is generally found under water and gets exposed when the tide becomes abnormally low. The species in this zone are not well used to extreme temperatures and long duration of dryness.
Some of the common organisms found in both spray and low tide zones are isopods and limpets.
Answer:
Explanation:
S phase. In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.
Answer: First, p53 triggers production of Cdk inhibitor proteins, pausing the cell cycle in G1 to allow time for repairs. ... In cancer cells, p53 is often missing, nonfunctional, or less active than normal. For example, many cancerous tumors have a mutant form of p53 that can no longer bind DNA.
