Answer:

dsRNA can inhibit gene expression by inhibition of transcription through heterochromatin formation.

dsRNA can inhibit gene expression by destruction of mRNA.

dsRNA can inhibit gene expression by inhibition of translation.

Explanation:

Eukaryotic gene expression, ds rna plays an important role in expression.

Double stranded RNA regulate gene expression by a process called RNA interference . In this process , ds rna is broken into short fragments which :

may lead to nuclear modification and increase heterochromatin;

may destroy mRNA by binding to specific regions ,

by modifying mRNA which inhibits translation.

By all these ways , ds rna can inhibit gene expressession.

So , Correct choices should be :

dsRNA can inhibit gene expression by inhibition of transcription through heterochromatin formation.

dsRNA can inhibit gene expression by destruction of mRNA.

dsRNA can inhibit gene expression by inhibition of translation.

To start scheduling messages in mass, first explore to the 'Publisher' segment, click BULK MESSAGE UPLOAD and download the example .csv document you'll load up with your posts.

It's critical to take note of that the best projects to utilize when working with this document are Google Docs, Text Edit and Textwrangler - Excel spreadsheets may not perceive a few characters.

Once the .csv record is open, start including your information.

In the main section, input the date in MONTH, DAY, YEAR or DAY, MONTH, YEAR arrange, trailed when you need the message to be distributed.

The time code must end with either a ZERO or a FIVE, and all messages must be planned no less than 10 minutes in front of when you intend to import the .csv record into Hootsuite.

On october 31, 2009, sky co. borrowed $16 million cash and issued a 7-month, noninterest-bearing note. the loan was made by star

mash [69]

Answer: Sky's effective interest rate on this loan is 8.39%.

In this question, we assume that interest is compounded annually.

Since Sky issues a non-interest bearing note, Star Finance will deduct 7 months' interest at 8% on the Face Value of the loan and pay the rest as principal to Sky.

Face value of the note $16 million

Discount Rate p.a 8%

Tenure of the note 7 months

$Discount on Note = Face Value * Discount Rate * \frac{Tenure in months}{Months in a year}$

$Discount on Note = 16 * 0.08 * \frac{7}{12}$

$Discount on Note = 0.746666667million$

[tex]Loan Amount received by Sky = Face Value - Discount on note[/tex]

$Loan Amount received by Sky = 16 - 0.746666667$

$Loan Amount received by Sky = 15.25333333 million$

So, Sky pays an interest of 0.746666667 on a sum of 15.25333333 for 7 months. This works out to a seven month interest of:

$Seven month Interest Rate = \frac{Interest}{Loan amount}$

$Seven month Interest Rate = \frac{0.746666667}{15.25333333}$

$Seven month Interest Rate = 0.048951049$

From this we can work out the effective interest rate for Sky as follows:

$Sky's Effective Interest Rate = Seven month interest rate * \frac{12}{7}$

$Sky's Effective Interest Rate = 0.048951049* \frac{12}{7}$

$Sky's Effective Interest Rate = 0.083916084$
