Missense

Structure determines function but you do not know if structure is altered in a way that inhibits/enhances function. Strictly speaking, benign missense mutation do exist. Of course if your professor told you otherwise, I'd stick with his/her story.

... in the resultant protein because the codon encodes the same amino acid e.g. If CAU is changed to CAC it does not matter as both encode histidine. Missense (or non-synonymous) mutations cause base substitution resulting in a codon which encodes a different amino acid e.g. Sickle cell disease is ...

i don't know the differences between these 2 mutation... look the same to me... and how do we know which mutation will be synonymous/ missense by looking at the change of codon?

I copied them down in a lecture I had in November last year. I hadn't noticed the missense of it before. I just thought someone who knows about UTIs might be able to help. My thought is that it means that the change in vaginal pH during pregnancy provides apt conditions ...

... Point (single-site) mutations in DNA can occur through two possible way, 1-) The substitution of one base pair for another a-)Silent Mutation b-)Missense mutation c-)Non sense mutation 2-)The addition or deletion of a nucleotide pair
