Here is the answer that would best complete the given statement above. <span>The physical, chemical, and biological laws that operate today also in geologic past. This statement relates to the principle of </span>uniformitarianism. Hope this answers your question. Have a great day!
Answer: Option A
Explanation:
A paraphyletic group can be defined as the group of organism that includes the ancestors but not all of its descendants.
There are three kinds of phylogenetic groups that can be understood by the help of the diagram.
The phylogeny can be defined as the diagram which shows the evolutionary relationship of one organism from another.
Other groups are monophyletic groups, parsimonious et cetera which shows different evolutionary relationship with organisms.
Answer:
D-DNA molecule
Explanation:
The process of copying the sequence of DNA nucleotide sequences to the mRNA is called Transcriptions. It is the first stage in gene expression for protein synthesis, and<u> it involves the unwinding of the DNA double strands molecules by enzyme</u><u> </u>DNA Helicase into two free strands,(by melting the hydrogen bonds between organic bases), a process initiated by the binding of enzymes RNA Polymerase to the promoter sites on the DNA template; the alignment of the mRNA nucleotides on the single DNA template strands in 3'-5 direction; the formation of hydrogen bonds between the organic bases of the template DNA and that of the messenger RNA single strands,( and phosphodiesterbonds within RNA nucleotide ), to form DNA-RNA complex.
The copying is done in complimentary anti parallel fashion;5'-3' prime. direction.
The hydrogen bonds, between the bases DNA-RNA complexes breaks,and the releases the mRNA which exists through the nuclear pores.Thus this <u>leads to copying of the the coded messages as seqeunce of DNA , from the DNA to the mRNA for gene expressions.</u>
Anticodons are found on molecules of tRNA. Their function is to base pair with the codon on a strand of mRNA during translation. This action ensures that the correct amino acid will be added to the growing polypeptide chain. A tRNA molecule will enter the ribosome bound to an amino acid.
hope this helps
