Discribe the processes of transcriotion and translation
gogolik [260]

Answer:

Please find the explanation of transcription and translation below using the key words.

Explanation:

Transcription is the process whereby a gene in a DNA template is used to synthesize a messenger RNA (mRNA) molecule in the nucleus of the cell. This process of transcription occurs with the aid of an enzyme called RNA POLYMERASE, which adds the nucleotides complementary to the one it reads in the gene to the growing mRNA strand.

Translation, on the other hand, is the second process of gene expression involving the synthesis of proteins from the mRNA sequence. This process occurs in the RIBOSOME where a group of three nucleotides in the mRNA called CODON is read by another group of complementary nucleotide in the transfer RNA (tRNA) called ANTICODON. The tRNA then carries amino acids corresponding to what is read in the codon to the growing polypeptide chain.

1. Do these results support the claim that application of the jewelweed is a good treatment for symptoms caused by poison ivy? E
-Dominant- [34]

A claim is an unverified statement or theory which is made about something which may or may not be true.

<h3>Verification of a claim</h3>

For a claim to be validated, i.e, proven to be true (in science), then there needs to be tests and experiments which needs to be carried out to show that the claim is valid.

With this in mind, if for example if there's a claim that jewelweed helps to treat symptoms caused by poison ivy, then there needs to be a controlled experiment to see if this is true or not.

If after a series of experiments and it can be established without any iota of doubt, then the claim is valid and the scientific process will move to the next stage.

Please note that your question is incomplete so I gave you a general overview to give you a better understanding of the concept.

The Gap 2(G2) stage of Interphase

Explanation:

In a eukaryotic cell, the cell cycle refers to both -cell growth and cell division - leading to the production of identical daughter cells. The cell cycle is basically divided into interphase (I) and mitosis (M).

The interphase, during which the cell grows and replicates its DNA takes place by the following stages – Gap 1 (G1), Synthesis (S), Gap 2(G2).

The cells grow and increase in size during the G1 period.

The G2 phase or the second gap phase the cell utilizes energy and produces necessary proteins for undergoing chromosome manipulation and other organelles and prepares the cell for mitotic cell division.

DNA replication mainly takes place in the Synthesis or the S stage of interphase with each of the chromosomes (46) is replicated.  

Due to this DNA replication in the S stage, its content is doubled (4-N DNA content) when it enters the G2 stage and all the DNA is found within a single nucleus.

From his monohybrid crosses, Mendel developed his first law
Nikitich [7]

Answer:

Im confused but if your asking for Medel's first law it would be states that for the pair of alleles an individual has of some gene (or at some genetic locus), one is a copy of a randomly chosen one in the father of the individual, and the other if a copy of a randomly chosen one in the mother, and that a randomly chosen one will be copied
