Why is the fossil named Ida so important to comparative anatomists?

Fossils are usually named based on the following conditions-

the location in which they are found

named after the scientist who discovers it

the rock formation in which they are found

They are given two names, the genus and the species

These fossils are again categorized into different groups depending on the similarity in terms of form.

These names of the fossils are important to the comparative anatomists because it helps them in doing the comparative study and understand the causes of similarities and dissimilarities in terms of anatomy and also helps in understanding the evolutionary process of these organisms. For example, the fossil named 'Ida' is the primitive fossil that was found to be almost completely preserved. This fossil helped in comparative studies with other fossil species in a number of ways.

Explanation:

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
