Answer:
Vascular dementia
Explanation:
This is a neurologic condition that is brought about as a result a brain injury caused by ischemic damage e.g ischemic damage with atherosclerosis. Vascular dementia is disease of no known cure but it's effect can be treated or suppressed. It is characterized by patient or client suffering from it to have loss of memory, laughing or crying when it's unnecessary or at awkward times e.t.c it occurs as a result of damage of blood vessels in our brain or break down and it occurs as a result of stroke, diabetes and other factors.
Answer:
Option A , Genome
Explanation:
Microarrays that contains array of single stranded DNA are used to study thousands of gene expression for all the genes of a genome and are usually termed as DNA miscroarrays. These microarrays being single stranded allows attachment of complementary DNA strand to bind to their surface. The mRNA from the cell is extracted and converted into cDNA which is further used for DNA cloning.
Hence, option A is correct
The sequence of B) nucleotides in a DNA molecule determines the protein that will be produced.
Answer:
One band of light density and one band of heavy density.
Explanation:
According to conservative model of replication, the original strands do not separate from each other during replication. Hence, after replication the old strands are together and the new strands are together.
Here, cells were grown in 14N medium first so 14N was used for DNA replication and all DNA molecules had 14N. When the cells were transferred to 15N medium, only 15N was available for replication process. New DNA molecules would be synthesised using 15N (15N15N) and old DNA molecules have 14N (14N14N). Hence, in density gradient one band will be of light density (14N14N) and one band will be of heavy density (15N15N).
