Answer:
The amino acids are important for the growth of almost all the organisms from the yeast to humans. While culturing yeast at the lab conditions, proper growth media is required.
The yeast is not able to make leucine. When this yeast is grown in the YPD plate, the growth of yeast is supported. The YPD consists of peptones, glucose and yeast extract. This media is enriched with all the components required for the yeast growth. The SD plate is also known as synthetic plate that do not contain the essential amino acids and consists of only nitrogenous bases. The mutant yeast will unable to grown in this media as leucine is not available. The mutant can be grown on this plate if the plate is supplied with the external media consisting of leucine and other essential amino acids.
Answer:
D) It would contain less nitrogen.
Explanation:
In an investigation of the cycling of environmental gases, a student placed water and bromthymol blue in each of four test tubes as shown in the diagrams below. No additional items were placed in tube 1, a snail was placed in tube 2, an aquatic plant (elodea) was placed in tube 3, and both a snail and an elodea were placed in tube 4. The tubes were then stoppered and placed in bright light for 24 hours. The solution in tube 3 changes after 24 hours because it would contain less nitrogen.
The dfferent tubes are shown in the picture that I uploaded.
The answer is mutations in a gamete, I believe.
Answer:
5' AUGAAGUUUGGCUAA 3'
Explanation:
The process by which the information encoded in a DNA is used as a template to synthesize a mRNA is called TRANSCRIPTION. It is the first stage of gene expression carried out in the nucleus of eukaryotic cells and cytoplasm of prokaryotic cells by RNA polymerase enzyme.
The process of transcription follows the complementary base pairing rule, which says that Adenine base always hydrogen pairs with Thymine while Guanine pairs with Cytosine. During transcription, the Thymine base (T) is replaced by Uracil base (U). Hence, whenever RNA polymerase reads an A in the DNA, it synthesizes U in the mRNA and vice versa for T and A. The same applies for G and C.
For the DNA sequence;
3' TACTTCAAACCGATT 5'
The mRNA sequence will be synthesized;
5' AUGAAGUUUGGCUAA 3'
