Answer:
25000 fragments
Explanation:
A restriction enzyme can cut a random DNA sequence once per every 4^n where n = number of bases in the recognition site of enzyme.
There are 6 bases in Xbal's recognition site (TCTAGA) so it will cut once per every 4^6 = 4096 bases (4kb).
Total genomic size = 100000kb
So expected number of fragments = Total genomic size/Size of one fragment
= 100000/4
= 25000 fragments
Both tested the idea of spontaneous generation.
Answer:
Both studies support the concept that species operate within a narrow optimum temperature range and are coupled to enzymatic activity.
Explanation:
The studies shown in the question above started from the same concept to establish the scientific experiment and had the same objective related to the investigation as temperature changes in the environment where these organisms live influences the enzymatic activity and, therefore, the functioning of their organism, being able to including modifying the environment around them. In summary, we can say that the studies sought to support the concept that species operate within a narrow range of optimal temperature and are coupled with enzymatic activity.
Answer:
E. Nucleus
Explanation:
All living organisms were classified into three major domains viz: Eukarya, Archaea and Bacteria. Eukarya are referred to as EUKARYOTES while the other two domains are collectively referred to as PROKARYOTES.
The major basis of this classification is the presence or absence of a membrane bound NUCLEUS. Eukaryotes are organisms characterized by the possession of a membrane-bound nucleus that houses their genetic material (DNA) while prokaryotes lack a nucleus and hence, their genetic material is found naked in the cytoplasm. Although, prokaryotic cells lack other membrane-bound organnelles like Chloroplast, mitochondria etc. but nucleus is the basis of this classification:
EU meaning TRUE, KARYA meaning NUCLEUS, hence Eukarya means organisms will true nucleus.
Answer:
True.
Explanation:
They can be divided independently in plants.
