Currently, most organs that are harvested for transplant are transported from the donor to the recipient packed in ice and must

be implanted within a matter of hours. How is organ culture an improvement on this transport method?

Answer:

the correct answer is : Cultured organs can be kept alive for several weeks before transplant.

Explanation:

organ outside the body does not behaves in the same way as they do inside the body. these organs can be kept alive only when they are put into a culture solution, which can increase the shelf life of the organs by few weeks. it also reduces the chance of organ rejection. cultured organs can be kept alive for several weeks before transplant.

For each of the following features of nucleic acids, indicate whether it is true of DNA only, of RNA only, of both DNA and RNA,
suter [353]

Answer:

Nucleic acid is one of the four major macromolecules that is present in all life forms. It includes DNA ( deoxyribonucleic acid) and RNA (ribonucleic acid). It is made up of small unit called nucleotides.

A nucleotide contains a pentose sugar that is deoxyribose in DNA and ribose in RNA, nitrogenous base that is Adenine, Thymine, Cytosine, Guanine in DNA and Adenine, Uracil, Cytosine, Guanine in RNA, and a phosphate group.

It is synthesised by a process of comlementary base pairing ( such as in double stranded DNA, A pairs with T and G pairs with C).

DNA is converted to mRNA inside the nucleus of eukaryotic cell and mRNA is then translated to protein when it moves the cytosplasm of the cell.

Thus, the correct answers are as follows-

1) Is an inherently directional molecule, with an N-Terminus on one end and a C-Terminus on the other end - true neither for RNA or DNA.

2) Contains the base adenine- True for both DNA and RNA.

3) Contains the nucleotide deoxythmidine monophosphate- True for DNA

4) Occurs only in signle stranded form- True for both RNA and DNA( such as single stranded DNA in DNA virus, and RNA in single stranded RNA in AIDS virus).

5) Is synthesized by a process that involves base pairing- True for both DNA and RNA.

6) Is involved in the process of protein synthesis in the cytoplasm of the cells in the liver- True for RNA ( particularly messenger RNA, mRNA)

If alleles of two different genes assort independently during gamete formation then what should be the phenotypic ratio in the F
Pepsi [2]

Answer:

9:3:3:1

Explanation:

If alleles of two genes separate randomly during anaphase-I of meiosis, some new combinations of the alleles are formed in the gametes. A heterozygous genotype for two loci (let's support TtRr) produces a total of four types of gametes in 1:1:1:1 ratio (TR, Tr, tR, and tr). The random fusion of these gametes from two double heterozygous parents (TtRr x TtRr) gives a phenotype ratio of 9:3:3:1. Here, 9/16 F2 progeny exhibit dominant phenotype for both loci while 1/16 exhibits recessive phenotype for both the genes. Rest 3/16 and 3/16 F2 progeny express dominant trait for one gene and recessive for the other.
