Question- Which molecule is correctly paired with its building blocks?
Answer- carbohydrate-monosaccharides
Transposable elements are considered to be responsible for vast range of genome diversity and gene silencing.
Explanation:
Transposable elements are short sequences of DNA that have the ability to move from one location to another in the genome. During this process they copy themselves.
The entire process carried out by transposable elements to copy themselves and move from one location to another is called transposition.
Transposition may result in mutation and is potentially a major source of genome diversity and change. If a transposon inserts itself into the coding region of a gene,it interrupts the coding sequence and inactivates the gene expression.
In addition to this, a transposable element may contain transcription or translation termination signal that will block the gene expression downstream of insertion site.
the relationship between DNA, codons, amino acids, and proteins. During transcription, DNA is transcribed into messenger RNA when the the base codes in DNA are copied. mRNA serves as the code for assembling amino acids in a certain order.
Answer:
A) Cytochrome C reduction in healthy cells B) Cytochrome cause the oligomerization of APAF1 that cause the activation of Caspase-9, which activates the Caspase-3 and Caspase-7 that ultimately lead to apoptosis.
Explanation:
Apoptosis is the programmed cell death which is performed to get rid of unnecessary and damaged cells through biochemical changes in higher animals. In apoptosis the cell shrinks, cytoskeleton collapse, nuclear membrane disassemble and DNA break into fragments.
a) Cytochrome C is present in intermembranel spaces of mitochondaria and the heme group of cytochrome C accepts electrons from Complex bc1 and transferr to complex IV.<em> Thus as the healthy cells requires proper energy to perform its regular functions the cytochrome keep reducing rapidly in it and this inhibit the cytochrome to initiate the apoptosis in healthy cell.</em>
B) Cytochrome C is released from mitochondria in apoptotic cell and it cause the oligomerization of the inactive Apoptosis protease activating factor-1. It form apoptosome complex with APAF1 that initiate and activate the caspases. These caspases are then involved in degradation of protein.
