Most of us has normally-functioning tissue and organs even if the cell has multiple mutations because of DNA repair mechanism.This repair mechanism has multiple processes by which any damage in the genetic material can be repaired before the protein is synthesized.In human beings there are many factors like environmental factors and metabolic activities that can cause mutation in DNA but the repair system does not allows the abnormal DNA to form abnormal proteins this saves the abnormal functioning of tissues and organs .More than 1 million molecular lesions per cell are repaired, these lesions leads to structural damage and the damaged cells are killed by apoptosis. This repair system continues as the cells divide and any alteration in the DNA is solved prior to the protein synthesis this result sin normal functioning of tissues and organs.
1. AUG GAC CUA UAG
4. codons in mRNA .... and Triplets in DNA
<h2>A) is the correct option </h2>
Explanation:
Natural selection is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit
- In the given example of rabbits, those that strictly eat grass will even survive after drought because plants will try to keep themselves green and there will be no production of berries and flowers hence these rabbits will shift their food source to green plants and will be favored
- But those rabbits those that strictly eat berries and flowers will not be able to survive because they were strictly dependent on berries and flowers for their food as a result they will be unfit and natural selection will be against those rabbits
Three-letter sets, or codons, of nucleic acids "code" for individual amino acids. Amino acids form proteins.
Answer:
The protists include plant-like organisms such as algae, animal-like organisms such as amoebas, and fungus-like organisms such as slime molds. They are also very important to us. ... The slime molds are important to ecosystems because they are decomposers, which release vital nutrients back into the environment.
