5. Adenine and thymine base pair
6. Chargaff's base ratios
10. Hydrogen bonds exist between base pairs (A/T and G/C) allowing DNA to maintain the helical structure. Adenines and thymines have two hydrogen bonds, guanines and cytosines have three. When these hydrogen bonds are broken, this allows for "unzipping" of the DNA - which can then be replicated, transcribed/translated to RNA, etc.
Answer:
b. nuclear membrane
Explanation:
it gose nucleus membrane cell wall
Staying were they are and waiting to die.
The same protein, isoleucine, will be formed. No proteins will be formed at all. Tyrosine will be formed instead
It is true that all GAL structural genes have UAS elements in their enhancer regions.
UAS elements can be found in the enhancer regions of every GAL structural gene. An enhancer is a short portion of DNA (50–1500 bp) that can be bound by proteins (activators) to increase the likelihood of a particular gene being transcribed.
The GAL4-UAS system is a biochemical technique used to investigate gene expression and function in fruit flies. Two parts make up the system: the Gal4 protein, which is an activator of transcription in yeast, and the UAS (Upstream Activation Sequence), which is an enhancer to which GAL4 binds specifically to initiate transcription.
