Answer:
LysThrHis, LysHisThr, HisLysThr, HisThrLys, ThrLysHis, ThrHisLys
Explanation:
You easily combine the options for the tripeptide if you made a chart
Also you can calculate the posibilities with the factorial function in the calculatio (x!): 3*2*1 (you can multiplicate the number of amoniacids by the followed numbers until 1) = 6
Answer:
The discovery of the Double Dna Helix was done by Watson and Crick.
Oxygen is required for aerobic respiration. This reaction produces ATP (universal currency for energy) which our bodies use to survive. Without oxygen much less ATP is produced, as aerobic respiration cannot occur in the lack of oxygen. ATP can be formed by anaerobic respiration, in the lack of oxygen, but this produces far far fewer molecules of ATP. This also produces lactic acid causing us to become fatigued and tired. Thus oxygen is crucial to produce the maximum amount of ATP possible.
Glucose is the main molecule which is respired by our bodies to produce ATP/ energy, which our bodies use to survive. Oxygen and glucose react in the mitochondria to make ATP (release energy.) It therefore, is called a respiratory substrate.
Note: I'm avoided talking about the exact phases of respiration as it is usually not covered till college/ A level standards. If you would like to know exactly which reaction requires oxygen and how it's used (i.e. the stages of respiration) don't hesitate to ask.
Answer and Explanation:
The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.
- During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
The stages S and G2 follow the G1. Once the whole interphase is completed, mitosis occurs.
- During the S stage occurs the DNI replication process. At this point, it also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.
- G2 stage is the final one before the cellular division. Here it begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
Answer:
E. 6:3:3:2:1:1
Explanation:
Look at the attached picture to see the Punnett square for your problem.
The cross for this is snapdragons who are heterozygous for both traits so the cross would be:
<em>TtRr x TtRr</em>
As you can see in the image, you have the following genotype combinations with the corresponding phenotype combinations:
GENTOTYPE PHENOTYPE NUMBER
TTRR Tall - Red 1
TtRR Tall - Red 2
TTRr Tall - Pink 2
TtRr Tall - Pink 4
TTrr Tall - White 1
Ttrr Tall - White 2
ttRR Short - Red 1
ttRr Short - Pink 2
ttrr Short - White 1
The following phenotype combinations in summary would then be:
Tall - Pink: 6
Tall - Red: 3
Tall - White: 3
Short - Pink: 2
Short - White: 1
Short - Red: 1
So the ratio is 9:3:3:2:1:1
