original DNA sequence:TAC,CCA,TAG, CAC ,GTT,ACA, ACG you will transcribe this DNA strand in mRNA,then you will translate the amino acid sequence that the mRNA codes for.

Answers

Based on the DNA sequence: TAC,CCA,TAG, CAC ,GTT,ACA, ACG

The mRNA produced by transcription is: AUG, GGU, AUC, GUG, CAA, UGU, UGC. The amino acid sequence produced by translation is: Met, Gly, Isoleucine, Val, Glu, Cys, Cys.

What is transcription and translation in genetics?

Transcription is the process by which RNA molecules are made from DNA molecules.

The RNA molecules produced are known as messenger RNA or mRNA which are then used to make proteins.

Translation is the process by mRNA molecules are used to make proteins from amino acids at the ribosomes.

The nucleotides in the mRNA are read in triplets known as codons.

For the given DNA sequence: TAC,CCA,TAG, CAC ,GTT,ACA, ACG

The mRNA produced is: AUG, GGU, AUC, GUG, CAA, UGU, UGC.

The amino acid sequence is: Met, Gly, Isoleucine, Val, Glu, Cys, Cys.

Therefore, proteins are made from DNA through the process of transcription and translation.

As trees grow over time, the trees form new cells in circles called annual growth rings. These rings show the amount of
wood produced during one growing season or year, as well as the effects of different environmental conditions on the
tree. The figure shows the growth rings for two different types of trees growing in the same forest area

Answers

Due to differences in age and growth rate of the trees, the growth rings for two different types of trees growing in the same forest area may vary.

What are annual growth rings?

Annual growth rings are rings of cells which form as trees grow over time and these rings represent the amount of wood produced during on growing season.

Annual growth rings provides estimates of the age of trees.

Distinct annual growth rings are formed in trees growing in temperate regions where there are sharp climatic variations.

The diameter and thickness of growth rings of different trees vary since trees grow and different rates.

Therefore, the growth rings for two different types of trees growing in the same forest area may vary due to differences in age and growth rate of the trees.

Answers

The idea it can describe is that it is the transfer of information from one neuron to another.

Transfer of information

The nervous system is part of the body systems that helps in the transfer of information from nerve to nerve and from nerve to muscle tissues.

The presynaptic nerve is the nerve that sends the information that is to be conveyed in form of action potential impulses.

The impulses led to the release of neurotransmitters from the terminal of the presynaptic nerve to the synapse. This binds to the receptor if the postsynaptic cell which receives the message.

Guinea pig 3. Long fur (FF)

Answers

The fur length of the guinea pig will depend on the alleles present in the offspring, whether they are dominant or recessive.

What are dominant and recessive traits?

Dominant traits are characters which are always expressed in an offspring wherever they occur.

Recessive traits on the other hand are expressed only if the dominant trait is absent in the offspring.

In the trait for fur length in guinea pig, there are two alleles for it.

F is for long fur and is dominant f is for short fur and is recessive.

Thus, the possible combination of the two alles will be:

FF for long furFf for long fur andff for short fur

Therefore, the fur length of the guinea pig depends on the alleles present in th offspring, either dominant or recessive.
