RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is condensed and tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Nucleic acids like DNA stores all of an organism’s genetic information. Nucleic acid molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. Conversely, RNA nucleotides are Adenine, Guanine, Cysteine and Uracil. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule.

In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis. Thus, these contribute to the broad diversity of living organisms, as varied combinations of these 64 codons can produce many proteins which can be organized into cells, tissues and organisms.

An error sometimes made by beginning biology students is called the "Adaptationist Fallacy" wherin a trait observed in a populat

aleksley [76]

Answer:

The Adaptationist Fallacy can prove very costly to biologist who are assuming it wrong according to the function in the environment. Let us have an example of the phenotype of wheat diploid breed that produces non-bearded grains variety, but we cannot assume it as a beneficial phenotype without further extensive research. After research, we came to know that there is also a major hexaploid bearded variety, that produces more number of grains. That's how, the Adaptationist Fallacy may prove fatal if we have assumed diploid as a major beneficial phenotype.

Natural selection causes A. changes in allele frequencies within a population. B. changes in the mechanism of inheritance. C. th

wolverine [178]

Answer:

Natural selection causes change in allele frequencies within a population.

So option A is correct one.

Explanation:

Natural selection generally work on an organism’s phenotype, or observable features. Phenotype is often largely a product of genotype (the alleles, or gene versions, the organism carries). When a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the helpful alleles from one generation to the next – that is, it can cause microevolution.
