Answer:
Structures that are still present but currently serve little to no purpose
Explanation:
<em>Vestigial structures/organs are general defined as structures/organs that are present but poorly developed without any functional use in the present living organisms but thought to have been fully developed and functional in their ancestors.</em>
Fully developed and functional organs gradually become less developed and non-functional across generations as the environment keeps changing and organisms found lesser use for the organs. An example includes the <u>caudal vertebrae</u> found in man which is kind of useless but thought to have been fully developed and functional in the ancestors of man - the monkeys.
<u>Vestigial organs are often used as one of the morphological evidence of the evolution of living organisms.</u>
A. Cohesion is a property of water that describes the attraction due to hydrogen bonding between water molecules.
The researchers prepare an intron-free copy of the eukaryotic gene for the use in creating the transgenic bacteria by using the reverse transcriptase to make the cDNA from the mature mRNA
The structure of the eukaryotic genes. Most of the eukaryotic genes are contain the segments of the coding sequences (exons) that interrupted by the noncoding sequences (introns). Both the exons and the introns are transcribed to yield a long and primary RNA transcript.
Eukaryotic DNA is the linear, compacted into the chromosomes by the histones, and has the telomeres at each end to protect from the deterioration. The Prokaryotes contain the circular DNA in addition to the smaller, transferable DNA plasmids. Eukaryotic cells contain the mitochondrial DNA in the addition to the nuclear DNA
