Answer:
Lamellae
Explanation:
Chloroplasts are plant (also found in algae) organelles in which photosynthesis occurs. These structures contain pigments (such as chlorophyll) that have the ability to absorb light energy and convert it to sugars necessary for the growth and development of the plant.
Structure of the chloroplast: They are disc-shaped with outer and inner membranes and intermembrane space between them. Inside the chloroplast there is a fluid-filled space called stroma. Stroma contains membrane discs – thylakoids that are arranged in interconnected stacks called grana. In the thylakoid membrane is chlorophyll and inside the thylakoid disc is the space called the thylakoid space.
A DNA evidence provides the strongest support for the current Eubacteria phylogeny.
Answer:
It is associated with a sliding clamp only on the leading strand.
Explanation:
DNA polymerase must exhibit higher processivity for an efficient DNA replication process. The processivity is imparted by some specific subunits such as the beta subunit of DNA polymerase III. These subunits form a sliding clamp to allow the DNA polymerase to add a large number of nucleotides to the primer before detaching from the template.
Four copies of beta subunits of DNA polymerase III form a donuts shaped structure around each template strand of DNA and serve as a clamp. Each pair of beta subunits associated with core DNA polymerase. The function of these sub-units is to slide along DNA as replication processed. The sliding clamp does not allow the dissociation of DNA polymerase frequently and allows efficient replication of both leading and lagging strands.
Scientists routinely explore whether two different animal species have evolved from a recent common ancestor.Comparisons of items eaten for food is the LEAST useful technique to help with this determination
<h3><u>
Explanation:</u></h3>
The features that are related to the anatomy of two organisms when they share them in common indicates that they are evolved from the common ancestor. When there exists a common feature between any two species physically then it is inherited form the common ancestor.
The two species having common traits involves similar genetic material called DNA, genetic codes that are similar and same translation and transcription process. Thus studying about genes and gene expression will be helpful to explore whether two different animal species have evolved from a recent common ancestor than including the studies related to Comparisons of items eaten for food.
