Transposable elements make up 44% of the human genome. What is thought to be their function?

AfilCa [17]

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.

Answer:

.92 A = Is

Explanation:

Is = $\frac{Vp *Ip }{Vs}$

We're solving for Is, so plug in all the other given numbers.

Vp = 230 V

Ip = .020 A

Vs = 5.0 V

Is = $\frac{230 * .020}{5.0}$

= .92 A

if there are 500 people in a population, and 150 are homozygous HbA/hba, 150 are homozygous hbs/hbs, and 200 are heterozygous hb

sineoko [7]

Answer:

$0.547$

Explanation:

Given -

Total Population - $500$

Individuals with homozygous HbA/hbA genotype - $150$

Individuals with homozygous hbs/hbs genotype - $150$

Individuals with heterozygous hba/hbs genotype - $200$

Let us assume the given population is in Hardy Weinberg' equilibrium

The frequency of individuals in the given population with homozygous HbA/hba genotype is equal to number of individuals with homozygous HbA/hba genotype divided by total population.

$\frac{150}{500} \\= 0.3$

The frequency of hba allele is equal to

$\sqrt{0.3} \\= 0.5477$

Question is incomplete i have added full question in ask for detail section as well as in picture format with answer. See figure for clear explanation.

Answer:

(Twisted leaves)

The mutant allele is dominant to its corresponding wild-type allele

(Forked leaves)

The mutant allele is dominant to its corresponding wild-type allele

(pale leaves)

The mutant allele is neither dominant nor completely recessive to its corresponding wild-type allele
