In the process of photosynthesis, phytoplankton release oxygen into the water. Half of the world's oxygen is produced via phytoplankton photosynthesis. The other half is produced via photosynthesis on land by trees, shrubs, grasses, and other plants.
Answer:
Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins.
Explanation:
Genes tell your body how to make all its proteins. Each new cell in the growing embryo receives a full set of genes. But not every cell needs to make every protein and cells make some proteins only at certain times. Some genes are instructions for proteins that regulate the activity of other genes.
Answer:
B. a thread like DNA
Explanation:
Chromatin is basically DNA wrapped around histone proteins. There's two types: euchromatin (loosely packed) and heterochromatin (tightly packed)
Light is needed for the plants for photosynthesis. <span> No Light, No Reaction ! That means the plant wouldn't intake any </span>
Answer:
Histidine- Proline- Tryptophan- Stop codon
Explanation:
The mRNA strand in the question is produced as a result of a process called TRANSCRIPTION. However, the mRNA transcript is further used to synthesize an amino acid sequence in a process called TRANSLATION. The mRNA sequence is read in a group of three nucleotide bases called CODON.
Each codon specifies an amino acid which is represented in the GENETIC CODE. In this case, a sequence of mRNA strand is given as: CACCCAUGGUGA
The following codons in the sequence specify the following amino acid:
CAC - Histidine
CCA - Proline
UGG - Tryptophan
UGA - Stop codon
Hence, the amino acid sequence encoded by the given mRNA strand is Histidine- Proline- Tryptophan- Stop codon.
N.B: After a stop codon (UGA, UAA, UAG) is encountered, the translation process stops.
