On any there are a number of genes, but not all the genes will be coding for proteins.

a. tumor
b. chromosome
c. helix
d. nucleotide

genetic engineering

a. uses gene chips to track progress
b. uses recombinant dna technology to alter an organisms' dna
c. is used in genetic testing for certain inherited disease
d. is not currently being used but is an exciting possibility for the future

1. The right answer is B. Chromosome

In its most scientifically rigorous definition, a chromosome is a fully condensed structure of chromatin.

In optical microscopy, condensed regions formed of heterochromatin and decondensed regions of euchromatin are distinguished on the chromosomes. The genes expressed are located mainly at the level of euchromatin.

2. The right answer is B.

Genetic engineering is a technique of molecular biology allowing, in a controlled way, the study of gene modification: their isolation, their cloning, their sequencing, their cutting ... for a basic or applied research purpose. In medicine, it is used to produce recombinant proteins (from recombinant DNA) such as insulin.

my questions are always answered on spot you know whats the

you gotta always put the reward points high. if you r question takes long to answer and the reward points is just 5, then almost nobody will likely want to answer your question.

also, if your question is unclear, lacks information, nobody gonna answer.

people prefer multiple choice the best, its easy and quick when multiple choices questions. if you have long sentence questions on stories, essay, etc., then you have to at least give them as much points as possible.

it kinda like bounty , the question with most reward prize and the easiest to pull off will get

hope this

just saying your question will get reported and deleted an my answer too
