A single strand of DNA helix has the code CGCTAA. Which would be the complementary code on the other strand of the helix?

Yakvenalex [24]

The correct answer is option 4, that is, GCGATT.

Complementary strand refers to either of the two chains, which forms a double helix of DNA, with corresponding positions on the two chains comprising of a pair of complementary bases. It is a section of one nucleic acid, which is bonded to another by an alignment of base pairs.

In nature, complementarity refers to the base principle of DNA transcription and replication as it is a characteristic shared between the two RNA or DNA sequences, such that when they are arranged antiparallel to each other, the nucleotide bases at each position in the sequences will be complementary.

QUESTION 1 (5 marks) A molecule of messenger RNA (mRNA) has just been synthesized and processed in the nucleus of human cell wit

Dmitry [639]

1) DNA Template strand: TACAATCGACCCATC. 2) Anticodon: AAU. 3) mRNA carries genetic information to build the protein. 4) 5 amino acids. 5) Amino acids: Met, Leu, Ala, Gly, Tyr.

1)

<h3>What is the template strand?</h3>

When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments:

The coding strand that goes in 5' to 3' direction
The complementary strand -template strand- that grows in 3' to 5' direction .

The template strand is the one that is going to be complemented by the mRNA.

mRNA ⇒ AUGUUAGCUGGGUAG

DNA ⇒ TACAATCGACCCATC

Remember that pairs are as follows

T → A

A → U

G → C

<h3>What is an anticodon?</h3>

The anticodon is the sequence of three nucleotides that couples with the mRNA codon.

Each tRNA has two important sites. One of them is the anticodon that couples with the codon of the mRNA molecule. The other one carries the amino acid that is going to be addeded to the protein.

mRNA codons ⇒ AUG UUA GCU GGG UAG

tRNA anticodon ⇒ AAU

<h3>What is translation?</h3>

Translation is the stage of protein synthesis during which mRNA carries genetic information needed to synthesize the new protein in the cytoplasm.

Steps,

1- The formed mRNA moves to the cytoplasm through the nucleus membrane pores.

2- Once in the cytoplasm, mRNA meets a ribosome, the primary structure for protein synthesis.

3- Ribosomes are organelles composed of the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.

4- While the ribosome reads mRNA strain from its 5' extreme to 3', tRNA adds the correct amino acids to build the polypeptide.

The function of mRNA during translation is to take genetic information needed to build the protein.

4)

<h3>How many amino acids are determined per codon?</h3>

Each codon codes for only one amino acid.

There are cases in which different codons code for the same amino acid, but a single codon always codes for one amino acid.

mRNA codons ⇒ AUG UUA GCU GGG UAG

Amino acids ⇒ Met Leu Ala Gly Tyr

1 2 3 4 5

This mRNA segment represents 5 amino acids.

5)

Amino acids ⇒ Met Leu Ala Gly Tyr

What effect would fertilizers have if they entered the st.johns river ecosystem?

galben [10]

If fertilizers enter the St.Johns river they will result in nutrient overload, or eutrophication and harming the ecosystem of the river. The river will exceed its assimilative capacity for nitrogen and phosphorus. this will <span>deplete oxygen in the water needed by fish and reduce light that is essential to submerged vegetation. </span>

<h2>Simple contusion </h2>

Explanation:

Simple contusion in eye

Simple contusion is also known as bruise or commonly known as black eye which is used to describe the discoloration that occurs around an eye after a trauma to the eye or surrounding tissues
It is caused by broken blood vessels under the surface of the skin is typically accompanied by swelling
A serious condition that can accompany a black eye is bleeding inside the eye, in the space between the back side of the cornea and the front of the iris which is called hyphema

Scleral hemorrhage

Scleral hemorrhage also known as subconjunctival hemorrhage
When small and delicate blood vessels break beneath the tissue covering the white of the eye (conjunctiva), resulting eye redness then this condition is known as subconjunctival hemorrhage
A subconjunctival hemorrhage usually is benign, causing no vision problems or significant eye discomfort despite its conspicuous appearance
But eye redness also can be a sign of other types of potentially serious eye conditions
