What best describes a gene

A chromosome.

A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.

For apex it's "A piece of a chromosome."

Are smile dimples controlled by a recessive allele

Nope, the alleles for smile dimples are actually dominant, not recessive.

How are lysogenic and lytic cycles different

the lytic cycle causes disease

apex 2.1.6 During the iysogenic cycle, the cell is not killed

What should scientist do to find gene that produces protein after he located all the mrna produced by liver and cdna if he wants to artifically produce protein that is produced in liver of frogs

The scientist should mix the cDNA with the liver DNA.

An organism that reproduces sexually has a diploid number of 30 How many chromosomes will a gamete of this organism have

A gamete has half the diploid number of chromosomes, so in this case, the gamete would have 15 chromosomes.

What was the purpose of mendels expirements with dihybrid crossing

to find out if traits could effect the inheritance of other traits

Which sexx chromosomes do males have

Male humans have X and Y sex chromosomes.

Why does sexual reproduction result in more genetic variation in a species than asexual reproduction

Asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). Sexual reproduction produces a random mixture of the genetics derived from both parents.
In sexual reproduction, offspring are not identical to either parent.

Which of the following best describes how mRNA is produced

for apex, it's DNA provides a template for RNA polymerase.
