Scientists have found that extracellular matrix components may induce specific gene expression in embryonic tissues such as the

liver and testes. For this to happen, there must be direct communication between the extracellular matrix and the developing cells. Which kind of transmembrane protein would most likely be involved in this kind of induction? (A) integrins (B) fibronectins (C) actin microfilaments (D) receptor tyrosine kinases

Scientists have found that extracellular matrix component may induce specific gene expression in the embryonic tissues such as the liver and testes. For this to happen, there must be a direct communication between the extracellular matrix and the developing cells. The Integrins of transmembrane protein would most likely be involved in this kind of induction.

Integrins are the main principal receptors used by the cells of  animal to bind to the matrix of extracellular. They are heterodimers and they function as transmembrane linkers between the actin cytoskeleton and the extracellular matrix. A cell can regulate the sticky activity of its integrins from within.

Which of the following lists has the steps involved in the whole genome shotgun approach to Sequencing in the correct order? 1.
Paha777 [63]

Answer:

5,2,3,1 and 4.

Explanation:

Whole genome shotgun sequencing is the method in the genetics that are used to sequence the whole DNA fragments. Different DNA sequencing methods are chemical sequencing and Sanger sequencing.

The different steps that are involved in the whole genome shotgun sequencing are as follows. The DNA is isolated and  broken DNA with the help of the restriction enzymes. The genomic fragments are inserted into the cloning vector for its multiplication. These fragments are then transformed into the E.coli with the cloning vector. The sequence assembly is important step in the sequencing. Than the sequencing of the cloned fragments are done to find the sequence of the whole genome.

Thus, the correct sequence is 5,2,3,1 and 4.

Present Your Findings
stira [4]

Answer:

1. It depends what type of method you are using. if it is Height x Width x Length then it will not work for an irregular shape because it has extra pieces that would not be included.

2. The second method would work for both regular and irregular shapes because you would have to know or find out the volume of the regular shape to get the volume for the irregular shape.

3. It also depends on what you are doing, if you are doing a regular shape then use the first method, if it's an irregular shape then use the second method, if you do the maths correctly both should give you an accurate answer for what you want to achieve.

4. No, because the sugar would dissolve.

5. No, on this case the displacement method would not work because of the weight difference

How did the discovery of three categories of petite mutations in yeast lead researchers to postulate extranuclear inheritance of
Nat2105 [25]
<h3><u>Answer;</u></h3>

Whereas segregational petites exhibited Mendelian inheritance, both neutral and suppressive petites followed non-Mendelian patterns that were consistent with the involvement of an extranuclear agent

<h3><u>Explanation</u>;</h3>
  • Mutations that yield defective mitochondria are expected to make cells grow much more slowly. These mutants were called petites to describe their small colonies compared to large wild type colonies.
  • Petite mutants could not grow when cells had an energy source requiring only metabolic activity of mitochondria - needed sugar as well which is part of glycolytic pathway.
  • Segregational petites, segregated in mendelian manner during meiosis. mutations cause defects in genes in cell nucleus encode proteins necessary for mitochondrial function.
  • Vegetative petite mutants do not segregate in mendelian manner; two types: neutral and suppressive; carry mutations in mitochondrial genome itself; when two yeast cells are mated, daughter cells inherit mitochondria from both parents.
  • Neutral petites lack most of their mitochondrial DNA; when mated with wildtype, the wildtype give their mitochondria so all cells display a normal phenotype.
