Answer:
The correct answer is "mutations to homologous genes".
Explanation:
The missing options of this question are:
A) morphology.
B) the pattern of embryological development.
C) biochemical pathways.
D) habitat and lifestyle choices.
E) mutations to homologous genes.
The correct answer is option E) "mutations to homologous genes".
Modern cladograms do not use physical characteristics to establish evolutionary similarities among species. Modern cladograms are constructed from evidence from molecular systematics based on similarities in mutations to homologous genes. The more similar are the homologous genes, the less different their genetic sequences are, and are considered more closely related in their evolutionary tree.
Answer and Explanation:
There are three basic steps as initiation, extension and termination which occur in both eukaryotes and prokaryotes. For transcription of a gene to occur, the DNA double helix unwinds over a short region.
initiation: RNA polymerase enzyme is linked to specific portions called as promoter in DNA to start RNA synthesis after the DNA unwinds.
Elongation: the enzyme synthesizes RNA strand along the DNA chain.
Termination: RNA synthesis continues along the DNA strand until it encounters a signal representing termination of the process. The termination process happens as the transcription complex separation takes place on the DNA sequence.
When assembled in the nucleus,mRNA peels off and moves to the cytoplasm. Here, it attaches to the ribosomes.Protein synthesis is started with AUG codon which is at the beginning of the mRNA-carried code. As the mRNA moves along the ribosome its information is translated into the appropriate amino acids which are assembled into a polypeptide. this is called translaton.
My day was good, what about urs??
<u>Answer:</u>
Searches for its food sources by growing outward and retracts.
Option: (D)
<u>Explanation:</u>
-
The slime mold is a eukaryotic organism with a nucleus and they grow in warm regions on decaying log/vegetation.
- When food is available the slime mould exists as a single celled organism.
- When there is a shortage of food the slime mold extends into branches in search of food.
- It extends outward to the location where the food is present. Then it retracts to its initial position.
The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain
