When a couple seeks information concerning the cause of their infertility, which member of the couple is usually tested first? male female Which technique could be used to investigate distinctions between a muscle cell and a bone cell? Gene expression microarrays DNA variation screening Gene therapy Preimplantation genetic diagnosis PCR Which type of genetic test can be used to identify genetic and chromosomal abnormalities before pregnancy starts? Amniocentersis Newborn screening Chorionic villus sampling Preimplantation genetic diagnosis in vitro fertilization Today, an entire human genome can be sequenced in less than a day. This is a much shorter timespan than it took to originally sequence the human project genome project, which about: 78 years 45 years 30 years 15 years 2 years

Solution

1) female -
Infertility tests are dont to find out why the woman cannot become pregnant. Certain factors such as fertility age and no usage of birth control for more than 6 months are taken into consideration. Males are also tested. The semen sample of the male partner is taken to test for the mobility of the sperms.

2) Gene expression microarrays-
Also known as gene expression profiling used to study the level of expression of thousand of genes , also in their developmental stages.

3) Amniocentesis-
The amniotic fluid from around the sac of the fetus is taken and tested for any kinds of abnormalities, chromosomal aberrations such as Downs syndrome.

4) 15 years.
The project started in the year 1990 and ended in the year 2006.
