how does an organism use the information in dna

Answers

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

Explanation:

DNA's instructions are used to make proteins in a two step process.

1st- Enzynes read the information in a DNA molecule and transcribe it into an intermediary molecule called messenger ribonucleic acid (mRNA).

2nd- Information contained in the mRNA molecule is translated into amino acids, which are the building blocks of proteins.

Explain, using a named example, why many sex-linked diseases occur more frequently in men than women

Answers

Answer:

Because men have Y-chromosomes.

Explanation:

In women, the final chromosome is XX, but in men, it is XY. Because this Y gene is different, genetic disorders are typically linked to this chromosome. A mutation in the X chromosome is equally prevalent in the population, meaning that the Y chromosome makes a male more likely to have a disease because they are more likely to have a genetic disorder, due to having both an X and Y chromosome.
