How does MRNA turn into tRNA (4marks)
Answers
Answer:
Transfer RNA (tRNA) is a small RNA molecule that participates in protein synthesis. Each tRNA molecule has two important areas: a trinucleotide region called the anticodon and a region for attaching a specific amino acid. During translation, each time an amino acid is added to the growing chain, a tRNA molecule forms base pairs with its complementary sequence on the messenger RNA (mRNA) molecule, ensuring that the appropriate amino acid is inserted into the protein.

How might this change affect the structure and function of the protein?
Answers
Answer:
Explanation:
Three-dimensional folding of a protein is due to interactions among the R groups of the amino acids. Cysteine has a sulfhydryl group, which may form a disulfide bridge with another part of the polypeptide chain. Valine has no sulfhydryl group and is nonpolar, which will affect how the polypeptide will fold.

In what molecule does the energy from these high-energy electrons end up
Answers
The energy from these high-energy electrons ends up in ATP molecules.
What is the energy currency of the cell?The main molecule for storing and transferring energy in cells is adenosine 5'-triphosphate (ATP). It is frequently referred to as the cell's energy currency and is like the money that is kept in a bank. When the cell needs energy, ATP can be taken out and used to fuel processes or stored for use in later ones. Animals use ATP to retain the energy released during meal digestion.Plants use photosynthesis to absorb light energy, which they then store in ATP molecules. An adenine base is joined to a ribose sugar, which is joined to three phosphate groups, to form the nucleotide ATP. Two phospho-anhydride bonds, which have high energy, connect these three phosphate groups. Energy is released and ATP is changed into adenosine diphosphate when one phosphate group is removed by breaking a phosphoanhydride bond during a procedure known as hydrolysis (ADP).When phosphate is taken out of ADP to create adenosine monophosphate, energy is also released (AMP).In order to make unfavorable reactions in a cell favorable, this free energy can be transferred to other molecules. By creating fresh phosphoanhydride bonds, AMP can subsequently be converted back into ADP or ATP and used to store energy once more. As they take part in biological reactions, AMP, ADP, and ATP constantly undergo interconversion within the cell.To learn more about ATP molecules, refer to

Would DNA ligase inhibition affect the process of DNA synthesis?
a) Yes. Both leading and lagging strands would not be synthesized properly.
b) Yes. The lagging strand would not be synthesized properly.
c) No. Ligase is not necessary to bind Okazaki fragments together.
d) No. DNA polymerase can fix any mistakes caused by ligase inhibition.
Answers
Yes, DNA ligase inhibition would affect the process of DNA synthesis.
DNA ligase plays a crucial role in DNA replication by catalyzing the formation of phosphodiester bonds between adjacent nucleotides, sealing the gaps between Okazaki fragments on the lagging strand and joining the Okazaki fragments to form a continuous strand of DNA. Therefore, if DNA ligase is inhibited, the proper completion of DNA synthesis would be affected.
On the leading strand, DNA synthesis occurs continuously in the 5' to 3' direction, facilitated by DNA polymerase. While ligase is not directly involved in joining the newly synthesized leading strand, it is necessary for the final sealing of nicks in the DNA backbone, ensuring the integrity of the newly synthesized DNA.
On the lagging strand, DNA synthesis occurs in short fragments called Okazaki fragments, which are later joined together by DNA ligase. In the absence of ligase activity, the Okazaki fragments would remain unconnected, leading to gaps in the lagging strand.
Although DNA polymerase possesses proofreading and repair activities, it primarily functions in synthesizing new DNA strands rather than repairing the gaps left by ligase inhibition. Therefore, the absence of ligase would impede the proper completion of DNA synthesis.

how does the gamete intra faloppian tube transfer procedure differ from in vitro fertilization
Answers
The gamete intrafallopian tube transfer (GIFT) procedure differs from in vitro fertilization (IVF) in that fertilization occurs inside the woman's fallopian tubes instead of in a laboratory setting.
In the GIFT procedure, the woman's eggs are retrieved, along with the man's sperm, through a minor surgical procedure. The eggs and sperm are then immediately transferred to the woman's fallopian tubes using a laparoscopic technique. Fertilization takes place naturally within the fallopian tubes, and the resulting embryos travel to the uterus for implantation.
On the other hand, in vitro fertilization (IVF), the most commonly known assisted reproductive technology, involves the fertilization of eggs with sperm in a laboratory dish outside the woman's body. After fertilization, the resulting embryos are cultured in the laboratory for a few days. Then, one or more embryos are transferred to the woman's uterus for implantation.
Therefore, the key difference lies in the location of fertilization: GIFT allows fertilization to occur naturally inside the woman's fallopian tubes, while IVF involves fertilization taking place outside the body in a laboratory. Both procedures aim to assist individuals or couples in achieving pregnancy, but they employ different techniques for fertilization and embryo transfer.
