Answer:
The best possible outcome for the cell in the event of mis-copied mRNA is for the mis-copied sequence to code for the same amino acid as the correct sequence would have done
Explanation: The process of transcription during which the message in DNA is transcribed as genetic codes into mRNA is sometimes not error proof. Synthesized mRNA is usually transported into the cytoplasm where the codes are translated into protein.
Each genetic code which is usually a sequence of 3 purine/pyrimidine bases codes for an amino acid. However, due to the degenerate nature of the genetic codes, more than one codon can code for the same amino acid. The degenerate nature is caused by the fact that there are 64 possible codons and there are 20 amino acids in nature. For example, UUA, UUU and UUG can be coding for the same amino acid in nature.
Hence, if a mistake occur during transcription, the best possible scenario for the cell is that the mis-copied sequence will end up coding for the same amino acid(s) as the correct correct sequence would.
Answer:
Fossil fuels are formed when organic matter such as the remains of animals and plants are buried and sequestered deep underground. The energy stored in these once-living things, as well as the process of being buried, causes the organic material to undergo a series of chemical transformations.
Answer:
a theory in biology that includes one or both of the statements that the cell is the fundamental structural and functional unit of living matter
The right answer is DNA.
The genetic information determines the characters of the organism (or micro-organism). It is passed from parents to their descendants.
DNA is the universal medium of genetic information in living beings. It consists of two chains wound in double helix. The two strands of DNA are the assembly of elementary molecules: the nucleotides.
Answer:
Haploid spores
Explanation:
Spores are usually haploid and unicellular and are produced by meiosis
