Given the mRNA sequence below, what would tRNA anticodons be in response? A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A
Lesechka [4]

Answer:

U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U

Explanation:

The mRNA (messenger RNA) is produced via the process of TRANSCRIPTION, which is the first stage of gene expression in living cells. The mRNA sequence formed is further read in the ribosomes in a group of three nucleotides called CODONS. This reading is done by another type of RNA called transfer RNA (tRNA).

The tRNA uses a set of three nucleotide bases that are complementary to that of the mRNA codons called ANTICODON. The anticodons are complementary to the mRNA codon i.e. A on the mRNA sequence will be read and recognized by U on the tRNA anticodon.

Hence, given the mRNA sequence: A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A, the tRNA anticodons that will read this sequence will be: U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U

Clarify the relationship between photosynthesis and cellular respiration
Liono4ka [1.6K]

Answer:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

How is the berries of a mountain ash, the helicopter seeds of maples and linden trees, the parachute seeds of the cottonwood tre
ehidna [41]
Well you see each of the seeds have developed a special technique that allows their individual seeds to travel further and lower the probability of landing close to the tree and not getting the sunlight it needs

For the berries birds and various animals eat them carrying them away so hopefully they can get more sunlight

Helicopter seeds do the same thing except the sides themselves float away from the tree to get  a further distance.

Finally the acorn seeds of the oak tree use the same concept of the berries. Various squirrels do eat these kinds of nuts and bury them in the ground in hopes of finding them later. But due to squirrels not remembering where they buried their acorn seeds the acorns are well away from the tree and start growing. 

So you see all of these tree seeds are specially developed to help it get away from the trees. Especially so that they can grow in a much better environment than the one provided to them initially.
