A good expression vector for protein expression in coli should have features like an origin of replication, a selectable marker, a promotor, an operator, and a ribosome binding site.
A Ribosome Binding Site (RBS) is a part or segment of the upstream part of a messenger RNA (mRNA) molecule which binds the ribosome to position the message correctly for the initiation of translation.
Selectable marker genes are conditionally dominant genes that confer an ability to grow in the presence of applied selective agents that are normally toxic to cells or inhibitory to growth, such as antibiotics and herbicides.

D, if I remember correctly, memorization isn’t a part of chromosomal alternations
I know some of them.
For instance, blood cells, nerve cells, sperm cells, and egg cells.
Answer:
The first and second hominids have a more recent common ancestor than the first and third hominids.
Explanation:
The similarity in DNA can definitely reveal us about common ancestry but it does not guarantee that the two species must be mating and reproducing. The best example to support this statement is that humans and chimpanzees share a common ancestor and both have so much similarity in their DNA. The DNA of humans and chimpanzees is around 99% similar but still humans and chimpanzees cannot mate to produce off springs. Several attempts have been made in past to obtain fertile off springs by mating humans and chimpanzees but so far their mating has not produced any fertile off spring.
The first process is called transcription where the DNA's information is used to make mRNA. The second process is called translation where the tRNA comes with an amino acid to drop off. A chain of amino acids will eventually be formed to create a protein. Transcription comes before translation. Think that you have to script something before you can translate it.
