Offspring inherit<u> one copy of each </u><u>gene</u><u> from both parents</u> if one or both parents passes on a gene with DNA that does not code for functional proteins, disorders like phenylketonuria can result.

<h3>How do parents pass on one copy of each gene to their children?</h3>

Their mother passes one copy on to them through the egg, while their father passes the other one along (via the sperm). Each egg and sperm have a single set of 23 chromosomes. Two copies of each chromosome and two copies of each gene are present when the sperm fertilizes the egg, resulting in the formation of an embryo.

An autosomal recessive metabolic genetic condition called phenylketonuria (PKU) is defined by a mutation that renders the gene for the hepatic enzyme phenylalanine hydroxylase (PAH) inactive.

Electrical conductivity tester.

If the bulb begins to glow brightly when the plug is submerged in the unknown solution then the solution has high conductivity. 

The bright glow of the bulb resulting from the experiment indicates that the current flows easily through the unknown liquid.

What are the advantages and disadvantages of using RNA or protein as genetic material?
larisa86 [58]

The most important idea is that the genetic material of any organism must be able to accurately replicate itself at least every generation (or for multicellular organisms at each cell division).  

Base pairing (A-T or U and C-G)allows DNA and RNA (eg in polio virus, see Wikipedia page on RNA dependent RNA polymerase) to create a copy of themselves, when the appropriate enzymes are present. Proteins have no way of making a copy of themselves.  

Stability is probably the main reason DNA is the most common genetic material. DNA has no enzymatic activity and was probably selected for to maintain the integrity of the genetic material (rather than having to perform a function for the cell/virus, during which it may be destroyed). The double helix structure also protects its integrity, and proofreading enzymes have also evolved which correct most of the mistakes made at DNA replication. RNA viruses don't have this mechanism- which could be said to be an advantage (as they can rapidly change and therefore avoid their hosts' immune systems), however in non-parasitic organisms most mutations in a gene would lead to a loss of an essential function and the extinction of that genome.  

I don't think either of these reasons are relevant, but I think the main reasons retroviruses convert their RNA to DNA are so they can use the host cell's replication machinery (this was they do not need to encode as many genes), and secondly they need avoid the antiviral mechanisms of the cell, which would destroy any double stranded RNA molecules found (even if the virus was single stranded, dsRNA would have to be produced at replication).

Answer:

23 chromosomes.

Explanation:

Human gametes have 23 chromosomes.Reproductive cells (gametes) are haploid - they have half the number of chromosomes as a body (somatic) cell. HOPE IT HELPS:)

The male japanese beetle breaks down female pheromes? what structure inside the cell of the male beetle breaks down the phermoon
Levart [38]

The right answer is the lysosome


The lysosome is a eukaryotic cell organelle.

The lysosome contains hydrolases, enzymes intended for the degradation of intracellular molecules. They are only active at acidic pH, hence the lowering of the pH in the vesicle.

The lysosome has a cellular garbage function, where the non-functional or undesired molecules are removed by digestion.
