呢兩日都係,學校老師叫我地呢兩日溫翻哂啲let leaning. 但溫完都好似好唔實在錦 淆底一個點

好,搵日去睇下先

諗住留番一份做當最尾溫多次書

dse用inspiratory centre同expiratory centre嘅inhibitory response去解釋breathing action係咪唔得

我剩係記左respiratory center nervous output點影響respiratory muscles
同埋chemoreceptor點樣刺激respiratory center
你講嗰啲未聽過

我想試下答,睇下有幾多分

1. Deletion at position will lead to a shift in nucleotide upstream;
which leads to a change in mRNA transcribed, the amino acids sequence translated will also be entirely different (i.e. AAG, TGC, GGC..). Production of enzyme I will be impaired as different protein folding lead to significant conformation changes and generation of malfunction proteins.

2. Only the amino acid sequence encoded at nucleotide position 4-6 will differ,
the remaining parts of the nucleotide sequence remains intact;
which will not lead to a significant difference in the entire protein structure.
Hence, the conformation and major enzyme function can be retained.

Can be mitosis/meiosis

想問下 即使條tendon斷咗 muscle係咪都依然可以contract
2018-04-04 23:16:02
tendon只係transmit pulling force
muscle contraction係nerve control令到myosin+actin郁 (out-syl)
