1. Pre-Cambrian Era.

1.1    Hadean

1.2    Archean

1.3    Proterozoic

2.    Paleozoic Era.

2.1    Cambrian

2.2    Ordovician

2.3    Silurian

2.4    Devonian

2.5    Carboniferous

2.6    Permian

2.6.1    Young earth creationist claims

2.6.2    "The Great Dying"

3.    Mesozoic Era.

3.1    Triassic

3.2    Jurassic

3.3    Cretaceous

3.3.1    K-Pg extinction

4.    Cenozoic Era.

4.1    Paleogene

4.2    Neogene

4.3    Quaternary.

According to this phyletic lineage, Cambrian (542 to 488 million years ago) and Silurian (443 to 416) are younger than Triassic (251 to 199), whereas Jurassic (199.6 to 145.5), Cretaceous (145 to 65), and Neogene ( 23 to 2.6) came later.

Answer  and  Explanation:

Image result for How did the results prove the semiconservative model of DNA

The experiment done by Meselson and Stahl demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template for synthesis of a new, complementary strand. Although Meselson and Stahl did their experiments in the bacterium E.

vfiekz [6]

Complete question:

A gene on strand of DNA has the following nucleotide sequence: CCCAAGTGG

A) GGG UUC ACC

B) CCC AAG TGG

C) GGG TTC ACC

D) UUU CCC AGA

Explanation:

What are the mRNA triplets coded for from this gene?

A) GGG UUC ACC

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.
