When vesicles of the cardiac sarcoplasmic reticulum (CSR) are incubated with ATP Mg^2+ and Ca^2+, they take up Ca^2+ and reach a
abruzzese [7]

Answer

I added 4 and 5 as an attachment due to time constraint.

Explanation:

1. at a steady state ca2+ taken by vesicle = 40n/mol

enclosed volume of CSR = 5μ/mg

concentration of ca2+ in vesicle =

40*10⁻⁶/5x10⁻⁶

= 0.008

= 8x10⁻⁹mol/L

2. radius of circle =75nM

volume = 150nm

volume of vesicle = 4/3 x pi x r³

= 1.33 x 3.14 x (75x10⁻⁹)³

= 1.77 x 10⁻²¹

when we convert this we get

1.77x10⁻¹⁸L since 1m³ is equal to 100oL

surface area =4x3.14x(75x10⁻⁹)²

= 12.56x5.625⁻¹⁵

= 7.065x10⁻¹⁴m²

this is 7.065x10⁻¹⁰cm²

3. number of vesicle/CSR

= 5x10⁻⁶/1.77x10⁻¹⁸

= 2.824x10¹²

surface are = 2.824x10¹² x7.06x10⁻¹⁰

= 19.95x10²

11111nata11111 [884]

Answer:

Site-directed mutagenesis

Explanation:

Site-directed mutagenesis (SDM) is a technique widely used in molecular biology in order to generate site-specific, targeted changes in the DNA sequence of a gene of interest. The SDM protocol consists of using a complementary oligonucleotide (primer) that contains the desired mutation, which hybridizes to the target DNA sequence and thus can trigger the desired mutation. Nowadays, the versatile CRISPR-Cas9 genome editing system is the most used technique to produce targeted mutations in any gene of interest.

Albinism is an autosomal recessive condition. Which answer choice shows the genotypic ratio when an albino female mates with a m
yKpoI14uk [10]

Answer:

The correct answer is - O AA: 2 Aa: 2 aa

Explanation:

In the given question there is an albino mother (aa), and a heterozygous male or father (Aa) crossed to generate offspring, the genotypic ration in between by this cross would be :

Gametes:

Albino mother - a, a

heterozygous male - A and a

Cross:

        a      a

A     Aa     Aa

a       aa      aa

Thus there are 2 heterozygous and two albino and no true breeding dominant present thus, the correct answer would be - O AA: 2 Aa: 2 aa
