According to the information given, the missing mRNA sequence strand is the 4th from the given option which is AUG AAA CGU CCU. As the complementary of A in RNA is U, G is C and for T is A.

Ans.

Protein synthesis involves the process of transcription and translation. During transcription parent DNA molecule acts as template and makes mRNA, which is complementary to parent DNA molecule.

According to base pair rule, in RNA adenine (A) binds with uracil (U) and guanine (G) binds with cytosine (c). Therefore, the resulting mRNA sequence will be 'AUG AAA CGU CCU,' when parent DNA sequence is 'TAC TTT GCA GGA.'

The mRNA contains information for the particular amino acids in the form of triplet codons or genetic codes, made up of three nucleotide bases. The genetic codes for given amino acid sequence are:

MET- AUG; LYS-AAA; ARG-CGU; PRO-CCU.

Thus, the correct answer is 'option). AUG AAA CGU CCU.'

Gastrulation, when the cells organize themselves into an embryo occurs 2 weeks after conception. What do the 3 layers of cells g

Travka [436]

Answer:

Gastrulation is the process where the developing embryo forms the process of the 3 germ layers. These germ layers are formed due to the movement of the single-layered blastula. Gastrulation starts during the third week of the human embryo.

The three germ layers give rise to different organs of the fetus. The 3 layers are ectoderm or outer layer, mesoderm or middle layer, and endoderm or inner layer.

These 3 germ layers give rise to different organs of the human fetus. Ectoderm forms epidermis, skin, hair, olfactory organs, eye lense. glands like pituitary. Sensory nerves, skeleton, pigment cells are also formed from ectoderm.

Ectoderm also forms a neural tube that further divides to form the brain, spinal cord.

Mesoderm form the vertebral column, skeletal muscle, excretory organs, reproductive organs. It also forms blood cells, blood vessels, body cavity or coelom.

The inner layer endoderm gives rise to the lining of the digestive tract, liver, pancreas, bladder, etc.

How many adductor muscles exist within the body? List them here.

Vladimir79 [104]

Answer:

Explanation:

Adductor muscles are those muscles which pulls the body part away from the midline of the body. It draws the body part to the extremities. These are found in various parts of the body such as human thigh bones such as adductor longus, adductor mugnus and adductor brevis. These muscles in the thigh helps in providing the flexibility and rotation.

In the thumbs there is adductor pollicis. In the toes there is adductor hallucis.
