Arrange the events of gene conversion of wild-type allele r to mutant allele r during meiotic recombination.

1 answer:

5 0

I found the whole exercise on the internet. Here are the events mentioned:
"-<span>Mismatched bases in the heteroduplex trigger mismatch repair.
-Gaps in the R (wild-type) allele sequence are filled by copying the r (mutant) allele.
-A heteroduplex is formed between </span>R (wild-type) and r (mutant) alleles.
-Mismatched bases are excised from the R (wild-type) allele.
-The wild-type R allele is converted to the mutant r allele."

The correct order is:
1. Gaps in the R (wild-type) allele sequence are filled by copying the r (mutant) allele.
2. A heteroduplex is formed between R (wild-type) and r (mutant) alleles.
3. Mismatched bases in the heteroduplex trigger mismatch repair.
4. Mismatched bases are excised from the R (wild-type) allele.
5. The wild-type R allele is converted to the mutant r allele.

It will catch this fish because the bears are not going to look down or behind them they're obviously since you're flying forward they're gonna look in front of them

The average radius of a molecule of lysozyme, and enzyme in tears, is 1430 pm. what is the radius in nanometers?

Galina-37 [17]

The average radius of a molecule of Iysozyme, an enzyme in tears, is 1430 pm.

The size of an element's nucleus and also the total number of electrons around it grow with an element's atomic number. The radius of an atom increases with increasing atomic number.

The calculation of conversion of radius is shown below:

It is known that, 1 meter is equal to 10¹² picometers.

We can use a conversion fraction to convert 1430 picometers to meters.

1430 pm × (1 m / 10¹² pm) = 1.430 × 10⁻⁹ m

1 meter is equal to 10⁹ nanometers.

Now, use a conversion fraction to convert 1.430 × 10⁻⁹ meters to nanometers.

1.430 × 10⁻⁹ m × (10⁹ nm/1 m) = 1.430 nm

Therefore, the radius of nanometers will be 1.430nm

Please place the following vessels in the correct order to represent the arterial circulation leading up to the glomerulus.

Ymorist [56]

The following vessels are connected as below:

aorta ->renal arteries ->segmental arteries ->interlobular arteries ->arcuate arteries ->cortical radiata ->afferent arteries ->glomerulus.

1) aorta : arises from heart which carry blood from heart to the rest of the body

2) renal artery :it arises from the aorta which carry blood to kidney .it carry unfiltered blood .

3)segmental arteries : it arises from renal artery .it has 5 branches or segments.

4)interlobular arteries : it arises from segmental arteries. the interlobular arteries pass directly outward between the medullary rays to reach the fibrous tunic ,where they end in the capillary network of this part.

5)Arcuate arteries: it arises from interlobular arteries .it is also known as arciform arteries, are vessels of the renal circulation. they are located at the border of the renal cortex and renal medulla.

6) cortical radiata: it arises from arcuate arteries.

7) afferent arteries: it arises from interlobular arteries and also connects to glomerulus. they are a group of blood vessels that supply the nephrons in many excretory systems .they play a important role in regulation of blood vessels.

8) glomerulus : it connects from afferent arteries.it is the filtering unit of kidney ,is a specialised bundle of capillaries that are uniquely situated between two resistance vessels.
