My sociology teacher says that gender is socially constructed. Is this true?

She has said that biological arguments are easily disproved, and that gender is a social construct with no inherent basis in human neurology. How true is this?

It depends on how she is using the word gender. Many differientiate between sex and gender with sex being the biological basis of division and gender being the socially constructed basis of division. For example, you could be a woman sex wise but you could dress and "pass" as a man socially, although it's not easily done. In this sense there is a difference between "transgender" and "transexual", where someone who is transgendered has switched from their "default" gender (e.g. crossdressing) and someone who is transexual has or is in the process of medical procedures to change their sexual organs/secondary sex characteristics (e.g. beards, brests). 

If she is using gender in this sense then it is socially constructed by definition. If however she is a radical feminists/social constructivist and she is using it to refer to gender/sex divisions generally, then certainly no. 

As a general rule, whenever anyone tells you that something is 100% socially constructed or 100% biologically predetermined, they are categorically wrong, and they usually have some political motive behind their claim.
