Nucleic acids are important information storage molecules present in virtually every cell. Which processes is carried out by a c
emmasim [6.3K]

Answer:

Transcription

Explanation:

The DNA is stored in the nucleus of the cell. The DNA has the sequence information of every gene. This means that depending on the DNA sequence, we are going to have a particular protein. The transcription is a process within the cell in which an enzyme called polymerase enters the nucleus and transcribes the DNA into another molecule, RNA. Let's say that this process makes another "copy" of the nucleic acid sequence, but now the RNA is able to get out of the nucleus carrying genetic information into the cytoplasm. In the cytoplasm, the RNA is translated into protein. During the translation, a ribosome "reads" the RNA and builds the protein depending on the nucleic acid sequence. To sum up, we can say that the transcription is the first process involved in accessing the information from the DNA.

Which of the following statements correctly describes how Mendel accounted for the observation that traits had disappeared in th
Genrish500 [490]

Answer:

A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.

Explanation:

Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.

When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.

Where do plants get the carbon needed to make glucose molecules during the process of photosynthesis?
rosijanka [135]

Answer:

From CARBONDIOXIDE (CO2) found in the atmosphere

Explanation:

Photosynthesis is a process performed by autotrophic organisms like green plants. It is a phenomenon whereby these plants manufacture their own food (sugars) using an inorganic carbon source in the presence of sunlight to provide energy.

The major end product of photosynthesis is glucose, which has a carbon constituent i.e. C6H12O6. However, this carbon needed to make glucose is got from an inorganic molecule called CARBON DIOXIDE, which the plants take from the atmosphere in via the stomata on their leaves.
